Ahybrid electric vehicle (HEV) is a type ofhybrid vehicle that couples a conventionalinternal combustion engine (ICE) with one or moreelectric engines into acombined propulsion system. The presence of the electricpowertrain, which has inherently betterenergy conversion efficiency, is intended to achieve either betterfuel economy or betteracceleration performance than aconventional vehicle. There is a variety of HEV types and the degree to which each functions as an electric vehicle (EV) also varies. The most common form of HEV is hybrid electricpassenger cars, although hybrid electrictrucks (pickups,tow trucks[2] andtractors),buses,motorboats,[3] andaircraft also exist.
Modern HEVs useenergy recovery technologies such asmotor–generator andregenerative braking to recycle the vehicle'skinetic energy toelectric energy via analternator, which isstored in abattery pack or asupercapacitor. Some varieties of HEV use an internal combustion engine to directly drive anelectrical generator, which either recharges the vehicle's batteries or directly powers the electrictraction motors; this combination is known as arange extender.[4] Many HEVsreduce idle emissions by temporarily shutting down the combustion engine atidle (such as when waiting at thetraffic light) and restarting it when needed; this is known as astart-stop system. A hybrid-electric system produces lesstailpipe emissions than a comparably sizedgasoline engine vehicle since the hybrid's gasoline engine usually has smallerdisplacement and thus lowerfuel consumption than that of a conventional gasoline-powered vehicle. If the engine is not used to drive the car directly, it can be geared to run at maximum efficiency, further improving fuel economy.
Ferdinand Porsche developed theLohner–Porsche in 1901.[3] But hybrid electric vehicles did not become widely available until the release of theToyota Prius inJapan in 1997, followed by theHonda Insight in 1999.[5] Initially, hybrid seemed unnecessary due to the low cost of gasoline. Worldwide increases in the price of petroleum caused many automakers to release hybrids in the late 2000s; they are now perceived as a core segment of the automotive market of the future.[6][7][better source needed]
As of April 2020[update], over 17 million hybrid electric vehicles have been sold worldwide since their inception in 1997.[8][9] Japan has the world's largest hybrid electric vehicle fleet with 7.5 million hybrids registered as of March 2018[update].[10] Japan also has the world's highest hybridmarket penetration with hybrids representing 19.0% of all passenger cars on the road as of March 2018[update], both figures excludingkei cars.[10][11] As of December 2020[update], the U.S. ranked second with cumulative sales of 5.8 million units since 1999,[12] and, as of July 2020[update], Europe listed third with 3.0 million cars delivered since 2000.[13]
Global sales are led by theToyota Motor Corporation with more than 15 millionLexus and Toyota hybrids sold as of January 2020[update],[8] followed byHonda Motor Co., Ltd. with cumulative global sales of more than 1.35 million hybrids as of June 2014[update];[14][15][16] As of September 2022[update], worldwide hybrid sales are led by the Toyota Prius liftback, with cumulative sales of 5 million units.[1] The Priusnameplate had sold more than 6 million hybrids up to January 2017.[17] Global Lexus hybrid sales achieved the 1 million unit milestone in March 2016.[18] As of January 2017[update], the conventional Prius is the all-time best-selling hybrid car in both Japan and the U.S., with sales of over 1.8 million in Japan and 1.75 million in the U.S.[17][9]
Hybrid electric vehicles can be classified according to the way in which power is supplied to the drivetrain:
In each of the hybrids above it is common to useregenerative braking to recharge the batteries.
Aplug-in hybrid electric vehicle (PHEV), also known as a plug-in hybrid, is a hybrid electric vehicle withrechargeable batteries that can be restored to full charge by connecting a plug to an externalelectric powersource. A PHEV shares the characteristics of both a conventional hybrid electric vehicle, having anelectric motor and aninternal combustion engine; and of anall-electric vehicle, also having aplug to connect to theelectrical grid. PHEVs have a much largerall-electric range as compared to conventional gasoline-electric hybrids, and also eliminate the "range anxiety" associated with all-electric vehicles, because the combustion engine works as a backup when the batteries are depleted.[21][23][24]
In December 2018,Toyota do Brasil announced the development of the world's first commercial hybrid electric car withflex-fuel engine capable of running with electricity and ethanol fuel or gasoline. The flexible fuel hybrid technology was developed in partnership with severalBrazilian federal universities, and a prototype was tested for six months using aToyota Prius asdevelopment mule.[25] Toyota announced plans to start series production of a flex hybrid electric car for the Brazilian market in the second half of 2019.[25][26]
Thetwelfth generation of the Corolla line-up was launched in Brazil in September 2019, which included an Altis trim with the first version of a flex-fuel hybrid powered by a 1.8-litreAtkinson engine.[27] By February 2020, sales of the Corolla Altis flex-fuel hybrid represented almost 25% of all Corolla sales in the country.[28]
To take advantage of the emission reduction potential of hybrid electric vehicles (HEVs), appropriate design of their energy management systems (EMSs) to control the power flow between the engine and the battery is essential.[29]
In a conventional (non-hybrid) vehicle, there is no need for an energy management strategy: the driver decides the instant power delivery using the brake and accelerator pedals and, in manual transmission vehicles, decides which gear is engaged at any time. In a hybrid vehicle, on the other hand, there is an additional decision that must be taken due to its ability to recover energy during braking or driving downhill: how much power is delivered by each of the energy sources on-board of the vehicle. The recovered energy can be stored in the battery and deployed at a later time to assist the prime mover to provide tractive power. This is why all hybrid vehicles include an energy management controller, interposed between the driver and the component controllers. As mentioned, the aim of the energy management system is to determine the optimal power split between the on-board energy sources. The decision regarding what to consider optimal depends on the specific application: in most cases, the strategies tend to minimize the fuel consumption, but optimization objectives could also include the minimization of pollutant emissions, maximization of battery life or—in general—a compromise among all the above goals.[30]
William H. Patton filed a patent application for a gasoline-electric hybrid rail-car propulsion system in early 1889, and for a similar hybrid boat propulsion system in mid-1889.[31][32] He went on to test and market the Patton Motor Car, a gas-electric hybrid system used to drivetram cars and smalllocomotives. A gasoline engine drove a generator that served to charge alead acid battery in parallel with the traction motors. A conventionalseries-parallel controller was used for thetraction motors. A prototype was built in 1889, an experimental tram car was run inPullman, Illinois, in 1891, and a production locomotive was sold to astreet railway company inCedar Falls, Iowa, in 1897.[33][34]
In 1896, the Armstrong Phaeton was developed by Harry E. Dey and built by theArmstrong Company of Bridgeport, CT for the Roger Mechanical Carriage Company. Though there were steam, electric, and internal combustion vehicles introduced in the early days, the Armstrong Phaeton was innovative with many firsts. Not only did it have a gasoline powered 6.5-liter, two-cylinder engine, but also a dynamo flywheel connected to an onboard battery. The dynamo and regenerative braking were used to charge the battery. Its electric starter was used 16 years before Cadillac's. The dynamo also provided ignition spark and powered the electric lamps. The Phaeton also had the first semi-automatic transmission (no manual clutch). The exhaust system was an integrated structural component of the vehicle. The Armstrong Phaeton's motor was too powerful; the torque damaged the carriage wheels repeatedly.[35]
In 1900, while employed at Lohner Coach Factory,Ferdinand Porsche developed theMixte,[3][36] a 4WD series-hybrid version of "System Lohner–Porsche" electric carriage that previously appeared in1900 Paris World Fair.[3][37] George Fischer sold hybrid buses to England in 1901; Knight Neftal produced a racing hybrid in 1902.[38]
In 1905,Henri Pieper of Germany/Belgium introduced ahybrid vehicle with an electric motor/generator, batteries, and a small gasoline engine. It used the electric motor to charge its batteries at cruise speed and used both motors to accelerate or climb a hill. The Pieper factory was taken over byImpéria, after Pieper died.[39] The 1915Dual Power, made by theWoods Motor Vehicle electric car maker, had a four-cylinderICE and an electric motor. Below 15 mph (24 km/h) the electric motor alone drove the vehicle, drawing power from a battery pack, and above this speed the "main" engine cut in to take the car up to its 35 mph (56 km/h) top speed. About 600 were made up to 1918.[40] The Woods hybrid was a commercial failure, proving to be too slow for its price, and too difficult to service. In England, the prototypeLanchester petrol-electric car was made in 1927. It was not a success, but the vehicle is on display inThinktank, Birmingham Science Museum.[41][42] TheUnited States Army's 1928Experimental Motorized Force tested a gasoline-electric bus in a truck convoy.[citation needed]
In 1931,Erich Gaichen invented and drove from Altenburg to Berlin a 1/2 horsepower electric car containing features later incorporated into hybrid cars. Its maximum speed was 25 miles per hour (40 km/h), but it was licensed by the Motor Transport Office, taxed by the German Revenue Department and patented by the German Reichs-Patent Amt. The car battery wasre-charged by the motor when the car went downhill. Additional power to charge the battery was provided by a cylinder of compressed air which was re-charged by small air pumps activated by vibrations of the chassis and the brakes and by igniting oxyhydrogen gas. No production beyond the prototype was reported.[citation needed]
During the Second World War, Ferdinand Porsche sought to use his firm's experience in hybrid drivetrain design for powering armored fighting vehicles for Nazi Germany. A series of designs, starting with theVK 3001 (P), the unsuccessfulVK 4501 (P) heavy tank prototype (which became theElefant tank destroyer) and concluding with the heaviest armored fighting vehicle ever prototyped, thePanzerkampfwagenMaus of nearly 190 tonnes in weight, were just two examples of a number of planned Wehrmacht "weapons systems" (includingthe highly-"electrified" subsystems on the Fw 191 bomber project), crippled in their development by the then-substandard supplies ofelectrical-grade copper, required for the electric final drives on Porsche's armored fighting vehicle powertrain designs.[citation needed]
Theregenerative braking system, a core design concept of most modern production HEVs, was developed in 1967 for theAmerican MotorsAmitron and calledEnergy Regeneration Brake by AMC.[43] This completelybattery powered urbanconcept car was recharged by braking, thus increasing the range of the automobile.[44] The AMC Amitron was first use of regenerative braking technology in the U.S.[45]
A more recent working prototype of the HEV was built byVictor Wouk (one of the scientists involved with theHenney Kilowatt, the first transistor-based electric car) and Dr. Charles L Rosen. Wouk's work with HEVs in the 1960s and 1970s earned him the title as the "Godfather of the Hybrid".[46] They installed a prototype hybrid drivetrain (with a 16-kilowatt (21 hp)electric motor) into a 1972Buick Skylark provided by GM for the 1970 Federal Clean Car Incentive Program, but the program was stopped by theUnited States Environmental Protection Agency (EPA) in 1976 while Eric Stork, the head of the EPA's vehicle emissions control program at the time, was accused of a prejudicialcoverup.[47]
In 1979 theFiat 131 Ibrido was presented in Detroit,[48][49] a marching prototype made by the CRF (Fiat Research Center). The engine compartment was composed by the 903cc borrowed from theFiat 127, set to output 33 hp only and coupled to a 20 kW electric motor. The scheme proposed byFiat is defined as "parallel hybrid": the petrol engine is connected to the differential with a 1:1 direct gear ratio, without gearbox, instead of the clutch there was an 8-inch torque converter followed by the transmission shaft on which the rotor of the electric motor is keyed, the latter powered by a 12-batteries pack.
The regenerative brake concept was further developed in the early 1980s by David Arthurs, anelectrical engineer, usingoff-the shelf components, military surplus, and anOpel GT.[50] Thevoltage controller to link the batteries, motor (a jet-engine starter motor), and DCgenerator was Arthurs'. The vehicle exhibited 75 miles per US gallon (3.1 L/100 km; 90 mpg‑imp)fuel efficiency, and plans for it were marketed byMother Earth News.[51]
In 1982,Fritz Karl Preikschat invented an electric propulsion and braking system for cars based on regenerative braking.[52] While clearly not the only patent relating to the hybrid electric vehicle, the patent was important based on 120+ subsequent patents directly citing it.[52] The patent was issued in the U.S. and the system was not prototyped or commercialized.
In 1988,Alfa Romeo built three prototypes of theAlfa 33 Hybrid,[53] equipped with the tried and testedAlfasudboxer engine (1,500cc, 95 HP) combined with a three-phase asynchronous electric motor (16 HP, 6.1 kgm of torque) supplied byAnsaldo ofGenoa. The design was realistic and already mass production-oriented, with minimal modifications to the standard body and a weight increase of only 150 kg (110 for the batteries, 20 for the electric engine and 10 for power electronics). The Alfa Romeo 33 Ibrida was able to travel up to 60 km/h in full electric mode, with a 5 km range, very good performance for the time.
In 1989,Audi produced its firstiteration of the Audi Duo (theAudi C3 100 Avant Duo) experimental vehicle, aplug-in parallel hybrid based on theAudi 100 Avantquattro. This car had a 9.4kilowatts (12.8 PS; 12.6 bhp)Siemenselectric motor which drove the rear roadwheels. Atrunk-mountednickel–cadmium battery suppliedenergy to the motor that drove the rear wheels. The vehicle's front roadwheels were powered by a2.3-litrefive-cylinderpetrol engine with an output of 100 kilowatts (136 PS; 134 bhp). The intent was to produce a vehicle which could operate on the engine in the country, and electric mode in the city. Mode of operation could be selected by the driver. Just ten vehicles are believed to have been made; onedrawback was that due to the extra weight of the electric drive, the vehicles were less efficient when running on their engines alone than standard Audi 100s with the same engine.[citation needed]
Two years later, Audi, unveiled the second duo generation, theAudi 100 Duo – likewise based on the Audi 100 Avant quattro. Once again, this featured an electric motor, a 21.3 kilowatts (29.0 PS; 28.6 bhp) three-phase machine, driving the rear roadwheels. This time, however, the rear wheels were additionally powered via theTorsen centredifferential from the main engine compartment, which housed a 2.0-litrefour-cylinder engine.[citation needed]
Research and Development was advancing in the 1990s with projects such as the earlyBMW 5 Series (E34) CVT hybrid-electric vehicle[54] In 1992,Volvo ECC was developed byVolvo. The Volvo ECC was built on theVolvo 850 platform. In contrast to most production hybrids, which use a gasoline piston engine to provide additional acceleration and to recharge the battery storage, the Volvo ECC used a gas turbine engine to drive the generator for recharging.
TheClinton administration initiated thePartnership for a New Generation of Vehicles (PNGV) program on 29 September 1993, that involvedChrysler,Ford,General Motors,USCAR, theDoE, and other various governmental agencies to engineer the next efficient and clean vehicle.[55] TheUnited States National Research Council (USNRC) citedautomakers' moves to produce HEVs as evidence that technologies developed under PNGV were being rapidly adopted onproduction lines, as called for under Goal 2. Based on information received from automakers, NRC reviewers questioned whether the "Big Three" would be able to move from the concept phase to cost effective, pre-productionprototype vehicles by 2004, as set out in Goal 3.[56] The program was replaced by the hydrogen-focusedFreedomCAR initiative by theGeorge W. Bush administration in 2001,[57] an initiative to fund research too risky for the private sector to engage in, with the long-term goal of developing effectively carbon emission- and petroleum-free vehicles.
1998 saw theEsparante GTR-Q9 became the first Petrol-Electric Hybrid to race at Le Mans, although the car failed to qualify for the main event. The car managed to finished second in class at Petit Le Mans the same year.

Automotive hybrid technology became widespread beginning in the late 1990s. The firstmass-produced hybrid vehicle was theToyota Prius, launched inJapan in 1997, and followed by theHonda Insight, launched in 1999 in theUnited States and Japan.[5] The Prius was launched inEurope,North America and the rest of the world in 2000.[59] Thefirst-generation Priussedan has an estimatedfuel economy of 52 miles per US gallon (4.5 L/100 km; 62 mpg‑imp) in the city and 45 miles per US gallon (5.2 L/100 km; 54 mpg‑imp) in highway driving. The two-doorfirst-generation Insight was estimated at 61 miles per US gallon (3.9 L/100 km; 73 mpg‑imp) in city driving and 68 miles per US gallon (3.5 L/100 km; 82 mpg‑imp) on the highway.[5]
The Toyota Prius sold 300 units in 1997 and 19,500 in 2000, and cumulative worldwide Prius sales reached the one million mark in April 2008.[59] By early 2010, the Prius global cumulative sales were estimated at 1.6 million units.[60][61] Toyota launched a second-generation Prius in 2004 and a third in 2009.[62] The 2010 Prius has an estimatedU.S. Environmental Protection Agency combined fuel economy cycle of 50 miles per US gallon (4.7 L/100 km; 60 mpg‑imp).[62][63]
TheAudi Duo III was introduced in 1997, based on theAudi B5 A4 Avant, and was the only Duo to ever make it into series production.[3] The Duo III used the 1.9-litreTurbocharged Direct Injection (TDI)diesel engine, which was coupled with a 21kilowatts (29 PS; 28 bhp) electric motor. Due to low demand for it because of its high price,[clarification needed] only about sixty Audi Duos were produced. Until the release of theAudi Q7 Hybrid in 2008, the Duo was the onlyEuropean hybrid ever put into production.[3][64]
TheHonda Civic Hybrid was introduced in February 2002 as a 2003 model, based on theseventh-generation Civic.[65] The 2003 Civic Hybrid appears identical to the non-hybrid version, but delivers 50 miles per US gallon (4.7 L/100 km; 60 mpg‑imp), a 40 percent increase compared to a conventional Civic LX sedan.[65] Along with the conventional Civic, it received a styling update for 2004. The redesigned 2004Toyota Prius (second generation) improved passenger room, cargo area, and power output, while increasingenergy efficiency and reducing emissions. The Honda Insight first generation stopped being produced after 2006 and has a devoted base of owners. A second-generation Insight was launched in 2010. In 2004, Honda also released a 6-cylinder hybrid version of theAccord but discontinued it in 2007, citing disappointing sales, although production of a 4-cylinder hybrid began in 2012.[66]
TheFord Escape Hybrid, the first hybrid electricsport utility vehicle (SUV), was released in 2005. Toyota and Ford entered into a licensing agreement in March 2004 allowing Ford to use 20 patents[citation needed] from Toyota related to hybrid technology, although Ford's engine was independently designed and built.[citation needed] In exchange for the hybrid licenses, Ford licensed patents involving their European diesel engines to Toyota.[citation needed] Toyota announced calendar year 2005 hybrid electric versions of theToyota Highlander Hybrid andLexus RX 400h with 4WD-i, which uses a rear electric motor to power the rear wheels, negating the need for a transfer case.
In 2006, General Motors Saturn Division began to market amildparallel hybrid, the 2007Saturn Vue Green Line, which utilized GM's BeltedAlternator/Starter (BAS Hybrid) system combined with a 2.4-litre L4 engine and an FWD automatic transmission. The same hybrid powertrain was also used to power the 2008Saturn Aura Green Line andMalibu Hybrid models. As of December 2009[update], only the BAS-equipped Malibu is still in (limited) production.
In 2007,Lexus released a hybrid electric version of their GS sport sedan, theGS 450h, with a power output of 335 bhp.[67] The 2007Camry Hybrid became available in summer 2006 in the United States and Canada.Nissan launched theAltima Hybrid with technology licensed by Toyota in 2007.[68]
Commencing in fall 2007,General Motors began to market their 2008Two-Mode Hybrid models of theirGMT900-basedChevrolet Tahoe andGMC Yukon SUVs, closely followed by the 2009Cadillac Escalade Hybrid[69] version.[70] For the 2009 model year, General Motors released the same technology in their half-ton pickup truck models, the 2009Chevrolet Silverado[71] andGMC Sierra[72] Two-Mode Hybrid models.
TheFord Fusion Hybrid officially debuted at theGreater Los Angeles Auto Show in November 2008,[73] and was launched to the U.S. market in March 2009, together with the second-generationHonda Insight and theMercury Milan Hybrid.[58]

Japan has the largest hybrid electric vehicle fleet in the world, as of March 2018[update], a total of 7.51 million hybrids registered in the country, excludingkei cars.[10] By 2016 it represented around 45% of cumulative global hybrid sales since their inception in 1997.[9] After 18 years since their introduction in the Japanese market, annual hybrid sales surpassed the 1 million mark for the first time in 2014. With cumulative sales of over 4 million hybrids through December 2014, Japan surpassed the United States as the world's largest hybrid market.[9][116][117] It was also the first time that all eight major Japanese manufacturers offered hybrid vehicles in their lineup.[117]
Japan also has the world's highest hybridmarket penetration,[11] as of March 2018[update], hybrids represented 19.0% of all passenger cars on the road.[10] The hybridmarket share of new car sales began to increase significantly in 2009, when the government implemented aggressive fiscal incentives for fuel efficient vehicles and the third generation Prius was introduced. That year, the hybrid market share of new car sales in the country, including kei cars, jumped from less than 5% in 2008 to over 10% in 2009. If only conventional passenger cars are accounted for, the hybrid market share was about 15%. By 2013 the hybrid market share accounted for more than 30% of the 2.9 million standard passenger vehicles sold, and about 20% of the 4.5 million passenger vehicles including kei cars.[194] Sales of standard cars in 2016 totaled 1.49 million units, with the hybrid segment achieving a record 38% market share. Accounting for kei cars, hybrids achieved a market share of 25.7% of new passenger car sales, up from 22.3% in 2015.[11] In 2016 every one of the standard cars listed in the Japanese top-20 best-selling car ranking had a hybrid version on sale.[11] and the two top-selling standard cars were models available only as a hybrid, the Toyota Prius and the Toyota Aqua.[195]

Hybrid sales in Japan almost tripled in 2009 as compared to 2008 as a result of government incentives that included ascrappage program,tax breaks on hybrid vehicles and other low-emission cars and trucks, and a higher levy on gasoline that rose prices in the order of US$4.50.[60][190][201] New hybrid car sales jumped from 94,259 in 2008[146] to 334,000 in 2009,[150] and hybrid sales in 2009 represented around 10% of new vehicles sales in Japan. In contrast, the U.S. market share was 2.8% for the same year.[60] These record sales allowed Japan to surpass the U.S. in total new hybrid sales, with the Japanese market representing almost half (48%) of the worldwide hybrid sales in 2009 while the U.S. market represented 42% of global sales.[150] TheToyota Prius became the first hybrid to top annual new car sales in Japan with 208,876 units sold in 2009.[60][202] The Insight ranked fifth in overall sales in 2009 with 93,283 units sold.[60]

This figure includes sales of thePrius α, launched in May 2011, and theToyota Aqua, launched in December. Despite keeping to the top-selling spot, total Prius sales for 2011 were 20% lower than 2010 due partly to the disruptions caused by the March2011 Tōhoku earthquake and tsunami, and also because government incentives for hybrid cars were scaled back.[204][205] Nevertheless, during the 2011Japanese fiscal year (April 1, 2011 through March 31, 2012), hybrid vehicles accounted for 16% of all new car sales in the country.[206] In May 2012, hybrid sales reached a record market share of 19.7% of new car sales in the country, includingkei cars.

The Toyota Auris HSD was the top-selling hybrid with 3,644 units, followed by the Prius (2,378) and theYaris Hybrid (1,587 ).[176]
As of February 2020, Hybrid cars as a proportion of all cars for sale in Ireland was very small, which could be seen in a snapshot (7 February 2020) of four car sales websites (Autotrader.ie, Carsireland.ie, Carzone.ie, and Donedeal.ie) that showed that out of circa 38,000 to 70,000 cars listed for sale, only circa 3.7% to 4.7% were Hybrids (including a small proportion of electric plug-in hybrids (PHEV)), so in real terms only 1,844-2,640 hybrid cars were advertised for sale in the market.
This very low level of Hybrids compared poorly to the circa 25,338 to 46,940 diesel engine cars available for sale on the same date, representing a much larger, circa 64-67% of the market at that time.
The Irish Government (to January 2020) had stated an aim to ban the sale of petrol, diesel and hybrid new ('non-electric') cars from 2030 (compared to the proposed EU ban by 2040, and the UK's proposed ban on the sale of new petrol, diesel and hybrid cars from 2035 as announced in the first week of February, 2020), though car dealers were reported to consider the Irish Government's target for one million electric and plug-in hybrid cars to be in use by 2030, as far too ambitious (The Irish Times, 07/02/2020).
A compromise in terms of transition to Electric Vehicles (EVs), and a non-electric car ban implementation around 2030, maybe for acceptance of Hybrid cars with modest size petrol engines (regardless of whether 'Full' or 'Mild' hybrids), for example those at/ less than 1.6Litre (1600cc) engine capacity, and/ or at circa 100g/km CO2, or less in terms of emissions, or a fuel efficiency rating (L/100 km) for Highway/Extra Urban and 'Combined' journeys.
The varieties of hybrid electric designs can be differentiated by the structure of thehybrid vehicle drivetrain, the fuel type, and the mode of operation.
In 2007, several automobile manufacturers announced that future vehicles will use aspects of hybrid electric technology to reduce fuel consumption without the use of the hybrid drivetrain. Regenerative braking can be used to recapture energy and stored to power electrical accessories, such as air conditioning. Shutting down the engine at idle can also be used to reduce fuel consumption and reduce emissions without the addition of a hybrid drivetrain. In both cases, some of the advantages of hybrid electric technology are gained while additional cost and weight may be limited to the addition of larger batteries and starter motors. There is no standard terminology for such vehicles, although they may be termedmild hybrids.
Gasoline engines are used in most hybrid electric designs and will likely remain dominant for the foreseeable future.[citation needed] Whilepetroleum-derived gasoline is the primary fuel, it is possible to mix in varying levels of ethanol created fromrenewable energy sources. Like most modernICE powered vehicles, HEVs can typically use up to about 15%bioethanol. Manufacturers may move toflexible fuel engines, which would increase allowable ratios, but no plans are in place at present.
The most prominent example of a full hybrid diesel system is theHYbrid4 by PSA Peugeot-Citroën. It was discontinued in 2016, following the decline in diesel popularity following the VWDieselgate scandal.Diesel-electric HEVs use adiesel engine for power generation. Diesels have advantages when delivering constant power for long periods of time, suffering less wear while operating at higher efficiency.[citation needed] The diesel engine's high torque, combined with hybrid technology, may offer substantially improved mileage. Most diesel vehicles can use 100% purebiofuels (biodiesel), so they can use but do not needpetroleum at all for fuel (although mixes of biofuel and petroleum are more common).[citation needed] If diesel-electric HEVs were in use, this benefit would likely also apply. Diesel-electric hybrid drivetrains have begun to appear in commercial vehicles (particularly buses); as of 2007[update], no light duty diesel-electric hybrid passenger cars are widelyavailable, although prototypes exist. Peugeot was expected to produce a diesel-electric hybrid version of its 308 in late 2008 for the European market.[242]
PSA Peugeot Citroën has unveiled two demonstrator vehicles featuring a diesel-electric hybrid drivetrain: thePeugeot 307,Citroën C4 Hybride HDi andCitroën C-Cactus.[243]Volkswagen made aprototype diesel-electric hybrid car that achieved 2 L/100 km (140 mpg‑imp; 120 mpg‑US) fuel economy, but has yet to sell a hybrid vehicle.General Motors has been testing theOpel Astra Diesel Hybrid. There have been no concrete dates suggested for these vehicles, but press statements have suggested production vehicles would not appear before 2009.
At the Frankfurt Motor Show in September 2009 both Mercedes and BMW displayed diesel-electric hybrids.[244]
Robert Bosch GmbH is supplying hybrid diesel-electric technology to diverse automakers and models, including thePeugeot 308.[245]
So far, production diesel-electric engines have mostly[vague] appeared inmass transit buses.[citation needed]
FedEx, along withEaton Corp. in the US andIveco in Europe, has begun deploying a small fleet of Hybrid diesel electric delivery trucks.[246]As of October 2007, Fedex operates more than 100 diesel electric hybrids in North America, Asia and Europe.[247]
There are bicycles that consist of an electric motor fitted turned by a generator powered from pedals almost similar to but different from pedal only bicycles. It also combines anElectric battery to store surplus power which can be charged fromregenerative braking, from battery chargers like aBattery electric vehicle orPlug-in hybrid and also from the pedal powered generator just like in aninternal combustion engine vehicle that uses theengine to charge the battery. It is quite likely that such vehicles are considered hybrids since power to the electric motor is coming from two sources (i.e. pedal power via a generator and battery power)).
Hyundai introduced in 2009 theHyundai Elantra LPI Hybrid, which is the firstmass production hybrid electric vehicle to run onliquefied petroleum gas (LPG).[75]
Hydrogen can be used in cars in two ways: a source of combustible heat, or a source of electrons for an electric motor. The burning of hydrogen is not being developed in practical terms; it is the hydrogen fuel-cell electric vehicle (HFEV) which is garnering all the attention.Hydrogen fuel cells create electricity fed into an electric motor to drives the wheels. Hydrogen is not burned, but it is consumed. This means molecular hydrogen, H2, is combined with oxygen to form water. 2H2 (4e−) + O2 --> 2H2O (4e−). The molecular hydrogen and oxygen's mutual affinity drives the fuel cell to separate the electrons from the hydrogen, to use them to power the electric motor, and to return them to the ionized water molecules that were formed when the electron-depleted hydrogen combined with the oxygen in the fuel cell. Recalling that a hydrogen atom is nothing more than a proton and an electron; in essence, the motor is driven by the proton's atomic attraction to the oxygen nucleus, and the electron's attraction to the ionized water molecule.
An HFEV is an all-electric car featuring an open-source battery in the form of a hydrogen tank and the atmosphere. HFEVs may also comprise closed-cell batteries for the purpose of power storage from regenerative braking, but this does not change the source of the motivation. It implies the HFEV is an electric car with two types of batteries. Since HFEVs are purely electric, and do not contain any type of heat engine, they are not hybrids.
Some vehicles like mostly cars and occasionally other vehicles combine the solarphotovoltaic cell propulsion system with anelectric battery that is charged by the solar panel or sometimes likeplug-in hybrid vehicles can also be charged from the power grid. These types of vehicles are technically hybrids, although they consist of two types of cells, since both of them use different fuels. The advantage of combining the two systems is that the vehicle can function with the battery if there is no sunlight and also reduces the risk of getting stuck on the road in case of a battery depletion since the solar panels charge the battery simultaneously.
Hybrid vehicles might use aninternal combustion engine running onbiofuels, such as aflexible-fuel engine running onethanol or engines running onbiodiesel. In 2007Ford produced 20 demonstrationEscape Hybrid E85s for real-world testing in fleets in the U.S.[248][249] Also as a demonstration project, Ford delivered in 2008 the first flexible-fuelplug-in hybridSUV to theU.S. Department of Energy (DOE), aFord Escape Plug-in Hybrid, capable of running on gasoline or E85.[250]
TheChevrolet Voltplug-in hybrid electric vehicle would be the first commercially available flex-fuel plug-in hybrid capable of adapting the propulsion to the biofuels used in several world markets such as the ethanol blendE85 in the U.S., orE100 inBrazil, or biodiesel inSweden.[251][252] The Volt will beE85flex-fuel capable about a year after its introduction.[253][254]
In some cases, manufacturers are producing HEVs that use the added energy provided by the hybrid systems to give vehicles a power boost, rather than significantly improved fuel efficiency compared to their traditional counterparts.[255] The trade-off between added performance and improved fuel efficiency is partly controlled by the software within the hybrid system and partly the result of the engine, battery and motor size. In the future, manufacturers may provide HEV owners with the ability to partially control this balance (fuel efficiency vs. added performance) as they wish, through a user-controlled setting.[256] Toyota announced in January, 2006 that it was considering a "high-efficiency" button.[citation needed]
One can buy a stock hybrid or convert a stock petroleum car to a hybrid electric vehicle using anaftermarket hybrid kit.[257]
Electric hybrids reduce petroleum consumption under certain circumstances, compared to otherwise similar conventional vehicles, primarily by using three mechanisms:[258]
Any combination of these three primary hybrid advantages may be used in different vehicles to realize different fuel usage, power, emissions, weight and cost profiles. TheICE in an HEV can be smaller, lighter, and more efficient than the one in a conventional vehicle, because the combustion engine can be sized for slightly aboveaverage power demand rather thanpeak power demand. The drive system in a vehicle is required to operate over a range of speed and power, but an ICE's highest efficiency is in a narrow range of operation, making conventional vehicles inefficient. On the contrary, in most HEV designs, the ICE operates closer to its range of highest efficiency more frequently. The power curve of electric motors is better suited to variable speeds and can provide substantially greater torque at low speeds compared with internal-combustion engines. The greaterfuel economy of HEVs has implication for reduced petroleum consumption andvehicle air pollution emissions worldwide[259]
Many hybrids use theAtkinson cycle, which gives greater efficiency, but less power for the size of engine.
Reduced noise emissions resulting from substantial use of the electric motor at idling and low speeds, leading toroadwaynoise reduction,[260] in comparison to conventional gasoline or diesel powered engine vehicles, resulting in beneficialnoise health effects (although road noise from tires and wind, the loudest noises at highway speeds from the interior of most vehicles, are not affected by the hybrid design alone). Reduced noise may not be beneficial for all road users, as blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets and feel quiet hybrids could pose an unexpected hazard.[261] Tests have shown that vehicles operating in electric mode can be particularly hard to hear below 20 mph (32 km/h).[262][263]
A 2009 study conducted by the NHTSA found that crashes involving pedestrian and bicyclist have higher incidence rates for hybrids thaninternal combustion engine vehicles in certain vehicle maneuvers. These accidents commonly occurred on in zones with low speed limits, during daytime and in clear weather.[264]
In January 2010 theJapanese Ministry of Land, Infrastructure, Transport and Tourism issued guidelines for hybrid and other near-silent vehicles.[265] The Pedestrian Safety Enhancement Act of 2010 was approved by theU.S. Congress in December 2010,[266][267][268] and the bill was signed into law by PresidentBarack Obama on January 4, 2011.[269] A proposed rule was published for comment by theNational Highway Traffic Safety Administration (NHTSA) in January, 2013. It would require hybrids and electric vehicles traveling at less than 18.6 mph (30 km/h) to emit warning sounds that pedestrians must be able to hear over background noises.[270][271] The rules are scheduled to go into effect in September 2014.[271][272] In April 2014 the European Parliament approved legislation that requires the mandatory use of Acoustic Vehicle Alerting Systems (AVAS) for all new electric and hybrid electric vehicles, and car manufacturers have to comply within five years.[273]
As of mid-2010, and in advance of upcoming legislation, some carmakers announced their decision to address this safety issue shared by regular hybrids and all types ofplug-in electric vehicles, and as a result, theNissan Leaf andChevrolet Volt, both launched in late 2010, and theNissan Fuga hybrid and theFisker Karmaplug-in hybrid, both launched in 2011, include synthesized sounds to alert pedestrians, the blind and others to their presence.[274][275][276][277] Toyota introduced itsVehicle Proximity Notification System (VPNS) in the United States in all 2012model year Prius family vehicles, including thePrius v,Prius Plug-in Hybrid and the standard Prius.[278][279]
There is alsoaftermarket technology available inCalifornia to make hybrids sound more like conventionalcombustion engine cars when the vehicle goes into the silentelectric mode (EV mode).[280] In August 2010 Toyota began sales in Japan of an onboard device designed to automatically emit a synthesized sound of an electric motor when thePrius is operating as anelectric vehicle at speeds up to approximately 25 kilometres per hour (16 mph). Toyota plans to use other versions of the device for use in gasoline-electric hybrids, plug-in hybrids,electric vehicles as well asfuel-cell hybrid vehicles planned formass production.[265]
The following table shows the fuel economy ratings and pollution indicators for the top ten most fuel efficient hybrids rated by theU.S. Environmental Protection Agency as of June 2016[update], formodel year 2015 and 2016 available in the American market.

Companies such asZero Motorcycles[283] andVectrix have market-readyall-electric motorcycles available now, but the pairing of electrical components and aninternal combustion engine (ICE) has made packagingcumbersome, especially for niche brands.[284]
Also, eCycle Inc produces seriesdiesel-electric motorcycles, with a top speed of 80 mph (130 km/h) and a target retail price of $5500.[285][286]
Peugeot HYmotion3 compressor,[287][288] a hybridscooter is a three-wheeler that uses two separate power sources to power the front and back wheels. The back wheel is powered by a single cylinder 125 cc, 20 bhp (15 kW) single cylinder motor while the front wheels are each driven by their ownelectric motor. When the bike is moving up to 10 km/h only the electric motors are used on astop-start basis reducing the amount of carbon emissions.[289]
SEMA has announced thatYamaha is going to launch one in 2010, withHonda following a year later, fueling a competition to reign in new customers and set new standards for mobility. Each company hopes to provide the capability to reach 60 miles (97 km) per charge by adopting advancedlithium-ion batteries to accomplish their claims. These proposed hybrid motorcycles could incorporate components from the upcomingHonda Insight car and its hybrid powertrain. The ability to mass-produce these items helps to overcome the investment hurdles faced bystart-up brands and bring new engineering concepts into mainstream markets.[284]
As emissions regulations become tougher for manufacturers to adhere to, a new generation of high-performance cars will be powered by hybrid technology (for example the Porsche GT3 hybrid racing car). Aside from the emissions benefits of a hybrid system, the immediately available torque which is produced from electric motor(s) can lead to performance benefits by addressing the power curve weaknesses of a traditional combustion engine.[290] Hybrid racecars have been very successful, as is shown by theAudi R18 andPorsche 919, which have won the24 hours of Le Mans using hybrid technology.[citation needed]
Since2014,Formula One cars have used 1.6 L turbocharged V6 engines, limited to 15,000 rpm. These engines allow Formula One cars to reach speeds of 372 km/h (231 mph),[291] as recorded byValtteri Bottas at the2016 Mexican Grand Prix.
_Hybrid_liftback%2c_SMRT_taxis_(2017-11-29).jpg)
In 2000,North America's first hybrid electric taxi was put into service inVancouver, British Columbia, operating a 2001Toyota Prius which traveled over 332,000 km (206,000 mi) before being retired.[292][293] In 2015, a taxi driver inAustria claimed to have covered 1,000,000 km (620,000 mi) in his Toyota Prius with the original battery pack.[294]
Many of the major cities in the world are adding hybrid taxis to their taxicab fleets, led bySan Francisco andNew York City.[295] By 2009 15% of New York's 13,237 taxis in service are hybrids, the most in any city in North America, and also began retiring its original hybrid fleet after 300,000 and 350,000 miles (480,000 and 560,000 km) per vehicle.[295][296] Other cities where taxi service is available with hybrid vehicles includeTokyo,London,Sydney,Melbourne, andRome.[297]
Hybrid technology for buses has seen increased attention since recent battery developments decreased battery weight significantly. Drivetrains consist of conventional diesel engines and gas turbines. Some designs concentrate on using car engines, recent designs have focused on using conventional diesel engines already used in bus designs, to save on engineering and training costs. As of 2007[update], several manufacturers were working on new hybrid designs, or hybrid drivetrains that fit into existing chassis offerings without major re-design. A challenge to hybrid buses may still come from cheaper lightweight imports from the former Eastern bloc countries or China, where national operators are looking at fuel consumption issues surrounding the weight of the bus, which has increased with recent bus technology innovations such as glazing, air conditioning and electrical systems. A hybrid bus can also deliver fuel economy though through the hybrid drivetrain. Hybrid technology is also being promoted by environmentally concerned transit authorities.
In 2003,GM introduced a hybriddiesel-electric military (light) truck, equipped with a diesel electric and a fuel cell auxiliary power unit. Hybrid electric light trucks were introduced in 2004 byMercedes-Benz (Sprinter) andMicro-Vett SPA (Daily Bimodale).International Truck and Engine Corp. andEaton Corp. have been selected to manufacture diesel-electric hybrid trucks for a US pilot program serving the utility industry in 2004. In mid-2005Isuzu introduced the Elf Diesel Hybrid Truck on the Japanese Market. They claim that approximately 300 vehicles, mostly route buses are using Hinos HIMR (Hybrid Inverter Controlled Motor & Retarder) system. In 2007, high petroleum price means a hard sell for hybrid trucks[298] and appears the first U.S. production hybrid truck (International DuraStar Hybrid).[299]
Other vehicles are:
Other hybrid petroleum-electric truck makers areDAF Trucks,MAN withMAN TGL Series,Nissan Motors andRenault Trucks withRenault Puncher.
Hybrid electric truck technology andpowertrain maker:ZF Friedrichshafen,EPower Engine Systems.
By avoice vote, theUnited States House of Representatives approved theHeavy Duty Hybrid Vehicle Research, Development, and Demonstration Act of 2009 ( forheavy dutyplug-in hybrid vehicles) authored by representativeJames Sensenbrenner.
Some 70 years after Porsche's pioneering efforts in hybrid-drivetrain armored fighting vehicles in World War II, theUnited States Army's manned ground vehicles of theFuture Combat System all use a hybrid electric drive consisting of a diesel engine to generate electrical power for mobility and all other vehicle subsystems. However, all FCS land vehicles were put on hold in the 2010DOD budget. Other military hybrid prototypes include theMillenworks Light Utility Vehicle, theInternational FTTS,HEMTT model A3, and theShadow RST-V.
In May 2003,JR East started test runs with the so-called NE (new energy) train and validated the system's functionality (series hybrid withlithium-ion battery) in cold regions. In 2004,Railpower Technologies had been running pilots in the US with the so-called Green Goats,[302] which led to orders by theUnion Pacific[303] andCanadian Pacific[304] Railways starting in early 2005.
Railpower offers hybrid electric roadswitchers,[305] as does GE.[306]Diesel-electric locomotives may not always be considered HEVs, not having energy storage on board, unless they are fed with electricity via a collector for short distances (for example, in tunnels with emission limits), in which case they are better classified asdual-mode vehicles.
For large boats that are already diesel-electric, the upgrade to hybrid can be as straightforward as adding a large battery bank and control equipment; this configuration can provide fuel saving for the operators as well as being more environmentally sensitive.[307][308]
Producers of marine hybrid propulsion include:
Ahybrid electric aircraft is anaircraft with an hybrid electric powertrain, as theenergy density oflithium-ion batteries is much lower thanaviation fuel, it effectively increase the range compared to pureelectric aircraft.By May 2018, there were over 30 projects, andshort-haul hybrid-electric airliners are envisioned by 2032.The most advanced are theZunum Aero 10-seater, theAirbus E-Fan X demonstrator, theVoltAero Cassio, theUTC modifiedBombardier Dash 8, and theAmpaire Electric EEL.
| Vehicle type | Fuel used |
|---|---|
| Combustion-only vehicle (ICE) | Exclusively usespetroleum or other fuel. |
| Micro hybrid electric vehicle (μHEV) | Exclusively uses petroleum or other fuel, but can shut off engine to consume less. |
| Mild hybrid electric vehicle (MHEV, BAHV) | Exclusively uses petroleum or other fuel, but has electric battery to consume less. |
| Plug-in hybrid vehicle (PHEV) | Uses mixture of petroleum or other fuel and electricity frompower grid. |
| All-electric vehicle (BEV, AEV) | Exclusively uses electricity from power grid. |
| Fuel cell vehicle (FCV, FCEV) | Exclusively useshydrogen or other fuel to generate electricity. |
HEVs can be initially more expensive (the so-called "hybrid premium") than purefossil-fuel-basedICE vehicles, due to extra batteries, more electronics and in some cases other design considerations (althoughbattery renting can be used to reach the cost parity). Thetrade-off between higher initial cost (also called showroom costs) and lower fuel costs (difference often referred to as thepayback period) is dependent on usage – miles traveled, or hours of operation, fuel costs, and in some cases, government subsidies. Traditional economy vehicles may result in a lower direct cost for many users (before consideration of anyexternality).
Consumer Reports ran an article in April 2006 stating that HEVs would not pay for themselves over five years of ownership. However, this included an error with charging the "hybrid premium" twice.[310] When corrected, theHonda Civic Hybrid andToyota Prius did have a payback period of slightly less than five years.[311] This includes conservative estimates with depreciation (seen as more depreciation than a conventional vehicle, although that is not the prevailing norm) and with progressively higher gas prices. In particular, the Consumer Reports article assumed $2/U.S. gallon for three years, $3/U.S. gallon for one year and $4/U.S. gallon the last year. As recent events have shown, this is a volatile market and hard to predict. For 2006, gas prices ranged from low $2 to low $3, averaging about $2.60/U.S. gallon.
A January 2007 analysis by Intellichoice.com shows that all 22 available HEVs will save their owners money over a five-year period. The most savings is for the Toyota Prius, which has a five-year cost of ownership 40.3% lower than the cost of comparable non-hybrid vehicles.[312]
A report in theGreeley Tribune says that over the five years it would typically take for a new car owner to pay off the vehicle cost differential, a hybridCamry driver could save up toUS$6,700 in gasoline at June 2007 gasoline prices, with hybrid tax incentives as an additional saving.[313]
In countries with incentives to fight againstglobal warming andcontamination and promote vehiclefuel efficiency, thepay-back period can be immediate, and all-combustion-engine vehicles can cost more than hybrids because they generate more pollution.
Toyota and Honda have already said they've halved the incremental cost of electric hybrids and see cost parity in the future (even without incentives).[314]

Therare-earth elementdysprosium is required to fabricate many of the advancedelectric motors and battery systems in hybrid propulsion systems.[315][316]
However, nearly all therare-earth elements in the world come fromChina,[317] and in 2008 one analyst estimated that an overall increase in Chinese electronics manufacturing may consume this entire supply by 2012.[316] In addition, export quotas on Chinese rare-earth exports have resulted in a generally shaky supply of those metals.[315][318]
A few non-Chinese sources such as the advancedHoidas Lake project in northernCanada andMt Weld inAustralia were under development,[318] however it is not known if these sources will be developed before a shortage hits.
In order to encourage the purchase of HEVs, several countries have introduced legislation forincentives andecotaxes.
Residents of Ontario and Quebec in Canada can claim a rebate on the Provincial Retail Sales Tax of up to Can$2,000 on the purchase or lease of a hybrid electric vehicle.[319] Ontario has a green license plate for hybrid car users and was to announce a slew of benefits to go along with it in 2008.[320] Residents in British Columbia are eligible for a 100% reduction of sales tax up to a maximum of $2,000 if the hybrid electric vehicle is purchased or leased before April 1, 2011 (extended in 2007/2008 budget from March 31, 2008, and expanded from a maximum of only $1,000 from April 1, 2008, to March 31, 2009, at which point the concession was scheduled to expire).[321] Prince Edward Island residents can claim rebates on the Provincial Sales Tax of up to Can$3,000 on the purchase or lease of any hybrid vehicles since March 30, 2004.[322]
InHaifa, hybrid vehicles are entitled to a free parking in city's parking lots for domestic citizens. Other cities, such as Petah-Tikva, have quickly adopted similar free parking for hybrid cars.

In 2009 the Japanese government implemented a set of policies and incentives that included ascrappage program, tax breaks on hybrid vehicles and other low emission cars and trucks, and a higher levy on gasoline that raised prices in the order of US$4.50 per gallon. New hybrid car sales for 2009 were almost triple those for 2008.[60][201]
InJordan, customs and sales tax reduced for all hybrid vehicles from 55% to 25% of the vehicle list price, 12.5% customs fees and sales tax, if the new hybrid is a replacement for an old car (more than 10 years age). However, in March 2018, the government resorted to imposing the 55% customs and sales tax back again in its efforts to increase revenue.
InMalaysia, since mid 2014 all (CBU) fully imported hybrid and EV cars sold inMalaysia significantly increased in price after the CBU hybrid and EV incentive package that expired on December 31, 2013. The affected cars areToyota Prius,Toyota Prius c,Honda Civic Hybrid,Honda Insight,Honda CR-Z,Lexus CT200h,Audi A6 Hybrid,Mitsubishi i-MiEV andNissan Leaf. However the exemption of excise duties and import taxes for hybrids and EV will be extended for models that are (CKD) assembled in Malaysia. The exemption will be extended until December 31, 2015, for hybrids and December 31, 2017, for EVs. Only the locally assembledHonda Jazz Hybrid,Mercedes-Benz S400 L Hybrid,Toyota Camry Hybrid and the facelifted Nissan Serena S-Hybrid are entitled for hybrid inducements.
In theNetherlands, the vehicle registration tax (VRT), payable when a car is sold to its first buyer, can earn the owner of an HEV a discount up to€6,000.
InChristchurch, hybrid vehicles are entitled to an hour free parking in city council parking buildings. Where those buildings already provide an hour free, hybrid vehicles are entitled to an extra hour free.
In theRepublic of Ireland, a discount of up to €1500 onVRT for hybrids, and up to €2500 for plugin hybrids was available until 31 December 2012.[323] Previously there was a potential reduction of 50% of VRT applicable before July 2008, when VRT rates were based on engine size, rather than the CO2 emissions system.[324] Some concerns were raised regarding the loss of VRT revenue due to the high number of expensive, luxury SUV hybrids imported, and also noting their large engine size, that in highway/extra-urban, and combined driving conditions may have negated much of the Hybrid engine arrangement emissions benefits (The Irish Times 11/11/2006).
InSweden there is an "Eco car" subsidy of SEK 10,000 (~ US$1,600) cash payout to private car owners. For fringe benefit cars there is a reduction of the benefit tax of 40% for EVs and HEVs and 20% for other "Eco cars".[325]
Drivers of HEVs in theUnited Kingdom benefit from the lowest band of vehicle excise duty (car tax), which is based oncarbon dioxide emissions. In centralLondon, these vehicles are also exempt from the £11.5 dailyLondon congestion charge.[326] Due to their low levels of regulated emissions, the greenest cars are eligible for 100% discount under the incentive system. To be eligible the car had to be on the Power Shift Register.[327] As of 2007[update], these included the cleanestLPG andnatural gas cars and most hybrid-, battery- and fuel cell-electric vehicles.
Through to December 31, 2010, the IRS permitted the purchaser of a hybrid electric car a federal incometax credit up to $3,400.[328] Thetax credit was to be phased out two calendar quarters after the manufacturer reached 60,000 new cars sold in the following manner: it was reduced to 50% if delivered in either the third or fourth quarter after the threshold was reached, to 25% in the fifth and sixth quarters, and 0% thereafter.[329]
As of April 2010, three auto manufactures reached the 60,000 cap;Toyota Motor Company reached it in 2007,Honda in 2008, and as of April 1, 2010, noFord Motor Company hybrid vehicles remained eligible for this tax credit.[330] Vehicles purchased after December 31, 2010, are not eligible for this credit, as this benefit will expire on this date.[328][330]
This latest milestone of 10 million units was achieved just nine months after total sales reached 9 million units at the end of April 2016.
