TheToyota Prius (/ˈpriːəs/PREE-əss) (Japanese:トヨタ・プリウス,Hepburn:Toyota Puriusu) is acompact/small family liftback (supermini/subcompactsedan until 2003) produced byToyota. The Prius has ahybrid drivetrain, combined with aninternal combustion engine and anelectric motor. Initially offered as a four-doorsedan, it has been produced only as a five-doorliftback since 2003.
The Prius was developed by Toyota to be the "car for the 21st century";[1][2] it was the first mass-produced hybrid vehicle,[3] first going on sale in Japan in 1997 atall four Toyota Japan dealership chains,[3] and subsequently introduced worldwide in 2000.[4]
In 2011, Toyota expanded the Prius family to include thePrius v, anMPV, and thePrius c, a subcompact hatchback. The production version of thePrius plug-in hybrid was released in 2012. The second generation of the plug-in variant, the Prius Prime, was released in the U.S. in November 2016.[5] The Prius family totaled global cumulative sales of 6.1 million units in January 2017, representing 61% of the 10 million hybrids sold worldwide by Toyota since 1997.[6] Toyota sells the Prius in over 90 markets, with Japan and the United States being its largest markets.[7]
Prius is aLatin word meaning "first", "original", "superior" or "to go before".[8]
In February 2011, Toyota USA asked the US public to decide on what the most properplural form of Prius should be, with choices including Prien, Prii, Prium, Prius, or Priuses.[9][10] The company announced on 20 February that "Prii" was the most popular choice, and the new official plural designation in the US.[11]
In Latinprius is the neuter singular of the comparative form (prior,prior,prius) of an adjective with only comparative and superlative (the superlative beingprimus,prima,primum). As with all neuter words, theLatin plural ispriora, but that brand name was used by theLada Priora in 2007. Despite the "official" plural form used by Toyota USA, "Priuses" is widely used in English.[12]
Beginning in September 2011, Toyota USA began using the following names to differentiate the original Prius from some newer members of the Prius family: the standard Prius became the Prius Liftback, thePrius v (known as the Prius α in Japan, and Prius + in Europe), thePrius Plug-in Hybrid, and thePrius c (called Toyota Aqua in Japan).[13][14]

In 1995, Toyota debuted a hybrid concept car at theTokyo Motor Show, with testing following a year later.[15] The first Prius, model NHW10, went on sale on 10 December 1997.[16][17] The first-generation Prius (NHW10) was available only in Japan.[18]
The first-generation Prius, at its launch, became the world's first mass-produced gasoline-electric hybrid car. At its introduction in 1997, it won theCar of the Year Japan Award, and in 1998, it won theAutomotive Researchers' and Journalists' Conference Car of the Year award in Japan.
Production commenced in December 1997 at theTakaoka plant inToyota, Aichi, ending in February 2000 after cumulative production of 37,425 vehicles.[19]
The NHW10 Prius styling originated from California designers, who were selected over competing designs from other Toyota design studios.[17]
The Prius NHW11 (sometimes referred to as "Generation II"[18]) was the first Prius sold by Toyota outside of Japan, with sales in limited numbers beginning in the year 2000 in Asia, America, Europe and Australia.[18][20] In the United States, the Prius was marketed between the smallerCorolla and the largerCamry, with a published retail price ofUS$19,995 (equivalent to $36,500 in 2024).[21] European sales began in September 2000.[22] The official launch of the Prius in Australia occurred at the October 2001Sydney Motor Show,[23] although sales were slow until the NHW20 (XW20) model arrived. Toyota sold about 123,000 first-generation Priuses.[24]
Production of the NHW11 model commenced in May 2000 at theMotomachi plant inToyota, Aichi, and continued until June 2003 after 33,411 NHW11 vehicles had been produced.[25] The vehicle was the second mass-produced hybrid on the American market, after the two-seatHonda Insight.[26]
The NHW11 Prius became more powerful partly to satisfy the higher speeds and longer distances that Americans drive.[27]Electric power steering was standard equipment.[28] While the larger Prius could seat five, its battery pack restricted cargo space. The Prius was offered in the US in three trim packages: Standard, Base, and Touring. TheUS EPA (CARB) classified the car with an air pollution score of 3 out of 10 as anUltra Low Emission Vehicle (ULEV).[29] Prius owners were eligible for up to aUS$2,000 federal tax deduction from their gross income.[26] Toyota executives stated that with the Prius NHW10 model, the company had been losing money on each Prius sold, and with the NHW11 it was now breaking even.[26]
_liftback_(2012-06-24).jpg)
Presented at theApril 2003 New York International Auto Show, for the 2004 US model year, the NHW20 Prius was a complete redesign. It became a compact liftback, sized between theCorolla and theCamry, with redistributed mechanical and interior space significantly increasing rear-seat legroom and luggage room. The second-generation Prius is more environmentally friendly than the previous model (according to the EPA), and is 6 inches (150 mm) longer than the previous version.[30][31] Its more aerodynamicKammback body balances length and wind resistance, resulting in a drag coefficient of Cd=0.26.[32] The development effort, led by chief engineerShigeyuki Hori, led to 530 patents for the vehicle.[33]
Production commenced in August 2003 at theTsutsumi plant inToyota, Aichi,[34] supplemented in October 2004 with theFujimatsu plant atKariya, Aichi.[35]
The Prius uses an all-electric A/C compressor for cooling, an industry first.[36] Combined with a smaller and lighterNiMH battery, the XW20 is more powerful and more efficient than the XW10.[37] In the US, the battery pack of 2004 and later models is warrantied for 150,000 miles (240,000 km) or 10 years in states that have adopted the stricterCalifornia emissions control standards, and 100,000 miles (160,000 km) or 8 years elsewhere.[38][39] The warranty for hybrid components is 100,000 miles (160,000 km) or 8 years.[40]
It is classified as aSULEV (Super Ultra Low Emissions Vehicle) and is certified byCalifornia Air Resources Board as an "Advanced Technology Partial Zero Emission Vehicle" (AT-PZEV).[41] In 2007, theUnited States Environmental Protection Agency (EPA) andCalifornia Air Resources Board (CARB) rated the Prius as among the cleanest vehicles sold in the United States on the basis of smog-forming emissions.[42]
From 2005 to 2009, the second-generation Prius had been built byFAW Toyota in the city of Changchun for the Chinese market.[43] It was reported that a total of 2,152 Priuses were sold in 2006 and 414 in 2007. The relatively low sales were blamed on a high price, aboutUS$15,000 higher than in Japan or the US, caused by high duties on imported parts.[44]In an attempt to stem the drop in sales, Toyota cut the price of Prius by up to eight percent in March 2008.[45] Toyota sold about 1,192,000-second-generation Priuses worldwide.[24]
Toyota debuted the new Prius (2010 US model year) at theJanuary 2009 North American International Auto Show,[46] and sales began in Japan on 18 May 2009.[47] Toyota cut the price of the Prius from¥2.331 million to¥2.05 million to better compete with theHonda Insight,[48] leading some to wonder whether increased sales of the Prius might come at the expense of sales of other vehicles with higher margins. Competition from lower priced hybrids, such as the Honda Insight, also made it difficult for Toyota to capitalize on the Prius's success.[49] As of June 2013[update], Toyota has sold about 1,688,000 third-generation Priuses worldwide.[24]
Among the new standard features of the Prius, Toyota introduced three user-selectable driving modes: EV mode for electric-only low-speed operation, Eco mode for bestfuel efficiency, and Power mode for better performance. Optional features included the solar-PV roof panels to help cool the cabin interior in summer heat, Intelligent Parking Assist, Lane Keep Assist, and Dynamic Radar Cruise Control.[50][51]
Its new body design features a reduced drag coefficient of Cd=0.25. This figure was disputed byGeneral Motors which found the value for the model with 17-inch wheels to be around 0.30 based on tests in GM, Ford, and Chrysler wind tunnels.[52]Car & Driver measured the third-generation Prius at 0.26 in a privately arranged five-way wind-tunnel test of comparable cars.[53] An underbody rear fin helps stabilize the vehicle at higher speeds.
A new front-drive platform underpinned the car, although the wheelbase remained unchanged and overall length grew by a lone centimetre. Aluminium was employed in the hood, rear hatch, front axle and brake calipers (disc brakes were finally assigned to all four wheels).[54]
The Prius uses a range of plant-derived ecologicalbioplastics, using wood or grass-derived cellulose instead of petroleum. The two principal crops used arekenaf andramie. Kenaf is a member of thehibiscus family, a relative to cotton and okra; ramie, commonly known as China grass, is a member of thenettle family and one of the strongest natural fibres, with a density and absorbency comparable toflax. Toyota said this was a timely breakthrough for plant-based eco-plastics because 2009 was the United Nations' International Year of Natural Fibres, which spotlights kenaf and ramie among others.[55]
At its introduction in 2009, it won theCar of the Year Japan Award for the second time. In December 2013,Consumer Reports named the Prius as the "Best Value", for the second year in a row.[56]
A 2019 iSeeCars study ranked the Prius as the second longest-kept vehicle among U.S. drivers.[57]
The fourth-generation Prius was first shown during September 2015 in Las Vegas,[58] and was released for retail customers in Japan on 9 December 2015. The launch in the North American market occurred in January 2016, and February in Europe & Middle East.
In August 2013, Toyota Managing Officer Satoshi Ogiso, who was chief engineer for the Prius line, announced some of the improvements and key features of the next generation Prius.[59][60] This was the first generation of the Prius to use theToyota New Global Architecture (TNGA) modular platform, which provides a lowercenter of gravity and increased structural rigidity. Ogiso also explained that the next-generation Prius plug-in hybrid, the Prius Prime, was developed in parallel with the standard Prius model.[61][62]
The 2018model year Prius Eco ranked as the second-most-fuel-efficient gasoline-powered car withoutplug-in capability available in the US that year, following theHyundai Ioniq Blue hybrid.[63][64]

In late November 2018, for the 2019 model year, the U.S. market Prius lineup introduced anall-wheel drive model featuring Toyota'sE-Four system. This has been available for theJapanese market Prius since 2015 and the hybrid versions of theRAV4 andLexus NX.[65] Also, the Prius received a facelift with redesigned headlights and tail lights, which was released in Japan on 17 December 2018.[66]
In 2021, for the 2022 model year, Toyota released the Nightshade Edition in the US. Like other Nightshade models, it added black paint to exterior trim pieces. It was available in FWD or AWD-e powertrain and in three exterior colours.[67]

The fifth-generation Prius was presented on 16 November 2022,[70] with two powertrain options announced for the Japanese market. The first uses Toyota'sSeries Parallel Hybrid System, available in 1.8-litre (2ZR-FXE) and 2.0-litre (M20A-FXS) variants and producing up to 103 kW (138 hp; 140 PS) and 144 or 146 kW (193 or 196 hp; 196 or 199 PS) respectively. This model is also available withE-Four all-wheel drive system. The second, aplug-in hybrid, combines a 2.0-litreM20A-FXS engine, anelectric motor andlithium-ion batteries to produce a combined output of 164 kW (220 hp; 223 PS).[71]
The new design has a higher drag coefficient of Cd=0.27 but it has a lower frontal area, and a smaller cargo volume than before.[72]
In Europe, deliveries will begin in the first quarter of 2023,[73] with only the plug-in hybrid model being available.[74]
Unlike previous generations, this generation will not be sold in Australia due to sluggish sales with the previous generation. It will be replaced by a shorter Corolla Hatchback Hybrid.[75] Toyota New Zealand also decided not to offer the new generation Prius initially, but have resumed sales in 2024 under their Signature Class imported vehicle program.[citation needed]
In October 2023, Toyota reversed its initial decision not to sell the fifth-generation Prius in the UK.[76]
In 2024, for the 2025 model year, the Prime model was renamed to Plug-in Hybrid for the North American market.[77]

In April 2024, Toyota issued a recall affecting 211,000 2023 and 2024 model year Prius and Prius Prime units worldwide where the rear doors can open unexpectedly if not locked due to a short circuit on the electronic rear door latches when the car is moving or involved in a collision.[98] The issue was that water could possibly short circuit the door lock. The issue has now been resolved, remaining vehicles that do not have new switches are replaced at US port of entry for vehicles shipped overseas.[citation needed]
ThePrius Plug-in Hybrid (ZVW35) is based on the conventionalthird generation (ZVW30) with a 4.4 kWhlithium-ion battery that allows anall-electric range of 18 km (11 miles).[99] A global demonstration program involving 600pre-production test cars began in late 2009 and took place in Japan, Europe, Canada, China, Australia, New Zealand and the United States.[100][101][102]
The production version was unveiled at theSeptember 2011 Frankfurt Motor Show.[103] Deliveries began in Japan in late January 2012,[104] followed by a limited roll-out in the U.S. in late February.[105] Deliveries began in Europe in June 2012 and in the UK in August 2012.[106][107]
The second generation of the plug-in hybrid version of the Prius, calledToyota Prius Prime in the U.S. and Prius PHV in Japan,[108] was developed in parallel with the standard fourth generation Prius model (XW50) released in December 2015.[109] The model was released to retail customers in the U.S. in November 2016,[5] followed by Japan in February 2017.[110] In the American market, unlike the first generation model, the Prius Prime is available in all 50 states.[109][111]
At theJanuary 2011 North American International Auto Show, Toyota revealed the 2012 model yearPriusv, an MPV, which is derived from the third-generation Prius and features over 50 per cent more interior cargo space than the original Prius design.
In May 2011, Toyota introduced the Prius α (alpha) in Japan, which is available in a five-seat, two-row model and a seven-seat, three-row model, the latter's third row enabled by a space-saving lithium-ion drive battery in the center console. The five-seat model uses a NiMH battery pack.[112][113] The Alpha is the basis for the five-seat Priusv launched in North America in October 2011 with anickel-metal hydride battery pack similar to the 2010model year Prius, and with two rows of seats to accommodate five passengers. The European and Japanese versions are offered with alithium-ion battery, with three rows of seats with accommodations for seven passengers. The seven passenger seating on the Prius v is not available on North American Prius v models.[114] The European version, named Prius+ (plus), began deliveries in June 2012.[106][112] US sales ended in 2017. Japanese production ended in March 2021.[115]
_i-Tech_hatchback_(2015-06-15)_01.jpg)
Toyota unveiled thePrius c concept at theJanuary 2011 North American International Auto Show. The Prius c has a lowerlist price and is smaller than the previous Prius liftback. The production version was unveiled at the2011 Tokyo Motor Show as the Toyota Aqua, and was launched in Japan in December 2011.[116] ThePrius c was released in the US and Canada in March 2012,[117][118] and in April 2012 in Australia and New Zealand.[119][120] The Prius c is not available in Europe, where instead, Toyota is selling theToyota Yaris Hybrid since June 2012.[121] The Prius c and the Yaris Hybrid share the same powertrain.[122]

Global cumulative Priusliftback sales reached the 1 million vehicle mark in May 2008.[123] Sales of one million were achieved in the U.S. by April 2011,[124] and Japan in August 2011.[125] As of September 2022[update], the Prius ranked as the world's top selling hybrid car with 5 million units sold.[70]
As of January 2017[update], the Prius is sold in over 90 countries and regions.[6] Worldwide cumulative sales[126] exceeded 2 million units in September 2010,[127] and reached 3 million in June 2013.[24] As of January 2017[update], global sales of thePrius family totaled almost 6.1 million units representing 61% of the 10 million hybrids delivered byToyota Motor Company (TMC) worldwide, including the Lexus brand.[6] Sales of the Prius family are led by the Prius liftback, with 4 million units, followed by the Aqua/Prius c with 1.4 million, the Prius +/v/α with, 615 thousand and the Prius Plug-in Hybrid with 79 thousand units.[6]
As of April 2011[update], the US accounted for almost half of Prius liftback global sales, with 1 million Priuses sold since 2000.[124] The Prius experienced two consecutive years of sales decreases from its peak in 2007, falling to 139,682 units in 2009[128] before rebounding to 140,928 units in 2010.[129][125] As of January 2017[update], sales of the Prius liftback totaled over 1.8 million units in Japan and 1.8 million in the US, and ranked as the all-time best-selling hybrid car in both countries.[6][130]
Cumulative Prius sales in Europe reached 200,000 units by mid-2010, after 10 years in that market. The UK is one of the leading European markets for Prius, accounting for 20% of Priuses sold in Europe.[131] Toyota Prius became Japan's best selling vehicle in 2009 for the first time since its debut in 1997 as its sales almost tripled to 208,876 in 2009.[132] In that year it overtook theHonda Fit, which was Japan's best-selling car in 2008 excludingKei cars.
Rising oil prices caused by theArab Spring led to increased sales in Q1 2011, but the2011 Tōhoku earthquake and tsunami led to a production stoppage. Production restarted, but output was hindered due to shortages from parts suppliers.[133] Nevertheless, during the 2011Japanese fiscal year, the Prius family sold 310,484 units, including sales of thePrius α, launched in May 2011, and theToyota Aqua, launched in December, allowing the Prius brand to become the best-selling vehicle in Japan for the third consecutive year.[134]
Until September 2012, the Prius liftback was the top selling new car in Japan for 16 months in a row, until surpassed by the Toyota Aqua in October, which kept the lead through December 2012.[135][136] The Prius liftback, with 317,675 units sold in 2012, was the best selling car in Japan during 2012 for the fourth consecutive year. The Aqua ranked as the second best selling car with 266,567 units sold in 2012.[135][137] Nevertheless, when sales of the two Prius models are broken down, the Toyota Aqua ranked as the top selling model in Japan in 2012, includingkei cars, leading sales since February through December 2012.[138][139] The Aqua was the top selling new car in Japan in 2013,[140] and again in 2014.[141] Global Prius sales peaked in 2010 with over 500 thousand units sold, and since 2011 sales of the liftback version have declined in most markets through December 2015, and in the US and Canada since 2013.[7]
High gasoline prices in the US, approachingUS$4 a gallon by March 2012, contributed to record monthly sales of Prius family vehicles. A total of 28,711 units were sold in the US during March 2012, becoming the one-month record for Prius sales ever. The third-generation Prius liftback accounted for 18,008 units (63%); thePrius v accounted for 4,937 units (17%); thePrius c, for 4,875 units (17%); and thePrius Plug-in Hybrid, for 891 units (3%).[142][143] Another record was set during the Q1 2012, with Prius family sales of 60,859 units, it became the best selling quarter ever.[144] Sales of Toyota Prius family vehicles in California represented 26% of all Prius purchases in the US during 2012. With 60,688 units sold during this year, the Prius became the best selling vehicle in California, ahead of theHonda Civic (57,124 units) andToyota Camry (50,250 units).[145] The Priusnameplate was again in 2013 the best selling vehicle in California with 69,728 units sold in the state, ahead of the Honda Civic (66,982) and theHonda Accord (63,194).[146][147]
Toyota sold 223,905 Priuses among the various HEV family members in the US in 2012, representing together amarket share of 51% of all hybrid sold in the country that year.[148] A total of 12,750 Prius PHVs were sold in 2012, allowing the plug-in hybrid to rank as the second top sellingplug-in electric car in the US after theChevrolet Volt, and surpassing theNissan Leaf.[149] The Toyota Prius liftback, with 147,503 units sold, was the best selling hybrid in 2012, thePrius v ranked third with 40,669 units, and thePrius c was fourth with 35,733 units.[148] Toyota USA estimated that sales of its hybrids models in 2012 would represent 14% of total Toyota sales in the country.[150] Since their inception in 1999, a total of 1.5 million Prius family members have been sold in the US by mid October 2013,[151] representing a 50.1% market share of total hybrid sales in the country. Of these, 1,356,318 are conventional Prius liftbacks sold through September 2013.[148][129][152][153]
Prius family sales also set a record in Japan in March 2012. Accounting for the conventional Prius and Prius α sales, a total of 45,496 units were sold in March 2012, becoming the highest monthly sales ever for any model in Japan since 1997, and representing a market share of 9% of all new car registrations excluding kei cars. The Toyota Aqua sold 29,156 units, ranking as the third top selling car that month. Together, all Prius family vehicles sold 74,652 units, representing 15% of monthly new car sales in March 2012.[154] With a total of 247,230 vehicles sold during the first quarter of 2012, the Toyota Prius family became the third top sellingnameplate in the world in terms of total global sales, after theToyota Corolla (300,800 units) and theFord Focus (277,000 units).[155][156]
US Prius sales have declined every year since their peak in 2012, due to competition from other manufacturers.[157]

The Prius is apower-split or series-parallel (full) hybrid, sometimes referred to as a combined hybrid, a vehicle that can be propelled by gasoline or electric power or both. Wind resistance is reduced by a drag coefficient of Cd=0.25 (0.29 for 2000 model) with aKammback design to reduce air resistance. Lower rolling-resistance tires are used to reduce road friction. An electric water pump eliminatesserpentine belts.[191] In the US and Canada, avacuum flask is used to store hotcoolant when the vehicle is powered off for reuse so as to reduce warm-up time. The Prius engine makes use of theAtkinson cycle.[192]
When the vehicle is turned on with the "Power" button, it is ready to drive immediately with the electric motor. In the North American second generation Prius, electric pumps warm the engine by pumping previously saved hot engine coolant from a coolant thermos[193] before the internal combustion engine is started. The delay between powering the car on and starting the internal combustion engine is a few seconds.[194] The third generation Prius does not have a coolant thermos. Instead, the engine is heated by recapturing exhaust heat. A button labelled "EV" maintains Electric Vehicle mode after being powered on and under most low-load conditions at less than 25 mph (40 km/h).[195] This permits driving with low noise and no fuel consumption for journeys under 0.5 miles (0.80 km),[196][197][198][199] Longer journeys are possible as long as the speed is kept below 25 mph (40 km/h), acceleration is kept low and the battery has enough charge. The engine starts automatically when the battery starts to run low. Prior to the 2010 model, the North American model did not have the "EV" button, although one can be added to enable the "EV" mode supported internally by the Prius Hybrid Vehicle management computer.[200][201] For the North American market, the third generation can remain in EV mode until 70 km/h (43 mph) depending on throttle and road gradient.[citation needed]
There are two batteries: the high voltage (HV) battery pack, also known as the traction battery, and a 12-volt battery known as the low voltage (LV) battery. The traction battery of the first generation Prius update (2000 onwards) was asealed 38-modulenickel metal hydride (NiMH)battery pack with a capacity of 1.78 kWh at a voltage of 273.6 V, and weighing 53.3 kg (118 lb)[202] and is supplied by Japan'sPanasonic EV Energy Co. They are normally charged between 40 and 60% of maximum capacity to prolong battery life as well as allow headroom forregenerative braking. Each battery pack uses 10–15 kg (22–33 lb) oflanthanum, and each Prius electric motor contains 1 kg (2 lb) ofneodymium; production of the car has been described as "the biggest user ofrare earths of any object in the world."[203] The LV battery provides power to the computer and various accessories such as wiper motors, headlights etc.
The Second Generation Prius contains a 1.310 kWh battery, composed of 28 modules. Each battery module is made of six individual 1.2 V 6.5 Ah Prismatic NiMH cells in series forming a 7.2 V 6.5 Ah module with 46 Wh/kg energy density and 1.3 kW/kg output power density.[204] Each module contains an integrated charge controller and relay. These modules are connected 28 in series to form a 201.6 V 6.5 Ah battery (traction battery), also known as the energy storage system. The computer-controlled charge controller and battery management computer systems keep this battery between 38% and 82% state of charge, with a tendency to keep the average state of charge around 60%. By shallow cycling the battery, only a small portion of its net available energy storage capacity is available for use (approximately 400 Wh) by the hybrid drive system, but the shallow computer-controlled cycling dramatically improves the cycle life, thermal management control, and net long term calendar life of the battery. Active cooling of this battery is achieved by a blower motor and air ducting, while passive thermal management was accomplished through the metal case design.[citation needed]
As the Prius reached ten years of being available in the US market, in February 2011Consumer Reports examined the lifetime and replacement cost of the Prius battery. The magazine tested a 2002 Toyota Prius with over 320,000 km (200,000 miles) on it and compared the results to the nearly identical 2001 Prius with 3,200 km (2,000 miles) tested byConsumer Reports 10 years before. The comparison showed little difference in performance when tested for fuel economy and acceleration. Overallfuel economy of the 2001 model was 40.6 miles per US gallon (5.79 L/100 km; 48.8 mpg‑imp) while the 2002 Prius with high mileage delivered 40.4 miles per US gallon (5.82 L/100 km; 48.5 mpg‑imp). The magazine concluded that the effectiveness of the battery has not degraded over the long run.[205] The cost of replacing the first generation battery varies betweenUS$2,200 andUS$2,600 from a Toyota dealer, but low-use units from salvage yards are available for aroundUS$500.[205] One study indicates it may be worthwhile to rebuild batteries using good blades from defective used batteries.[206]
TheHVAC system uses an ACinduction motor to drive a sealed-systemscroll compressor, a design principle not usually used in automotive applications. Using a scroll compressor increases the efficiency of the system while driving it with an AC induction motor makes the system more flexible, so theAC can run while the engine is off. Because the oil used with the refrigerant gas also flows in the area of the high-voltage motor-windings, the fluid must be electrically insulating to avoid transmitting electric current to exposed metal parts of the system. Therefore, Toyota specifies that apolyolester (POE) oil (designated ND11)[207] is required for repairs. The system cannot be serviced with equipment normally employed for regular cars, which typically use polyalkylene glycol (PAG) oil, as the equipment would contaminate the ND11 oil with PAG oil. According to SAE J2843, the oil provided from maintenance equipment must contain less than 0.1% PAG when filling. One percent PAG oil may result in an electrical resistance drop by a factor of about 10.[208]
Since its introduction, the Toyota Prius has been among the best fuel economy vehicles available in the United States, and for themodel year 2012, the Prius family has three models among the 10 most fuel-efficient cars sold in the country as rated byUS Environmental Protection Agency (EPA).[209] After theHonda Insight first generation was discontinued in September 2006, the Prius liftback became the most fuel-efficient car sold in the American market,[209][210][211] until it was topped by theChevrolet Volt in December 2010, as theplug-in hybrid was rated by EPA with an overall combined city/highway gasoline-electricity fuel economy of 60 mpg‑US (3.9 L/100 km; 72 mpg‑imp).[212] According to the EPA, for the model year 2012, and when only gasoline-powered vehicles are considered (excludingall-electric cars), the Prius c ranks as the most fuel-efficientcompact car, the Prius liftback as the most fuel-efficientmid-size car, and the Prius v as the most fuel-efficient mid-sizestation wagon.[213]
More fossil fuel is needed to build hybrid vehicles than conventional cars but reduced emissions when running the vehicle more than outweigh this.[214]

In 2008, the British government and British media requested that Toyota release detailed figures for the energy use and CO2 emissions resulting from the building and disposal of the Prius. Toyota has not supplied the requested data to address statements that the lifetime energy usage of the Prius (including the increased environmental cost of manufacture and disposal of the nickel-metal hydride battery) is outweighed by lower lifetime fuel consumption.[224] Toyota states that lifetime CO2 saving is 43 percent.[225] As of 2010[update], theUK Government Car Service operated over 100 Priuses (the largest part of its fleet) and lists the Prius as having the lowest CO2 emissions among its fleet.[226]
CNW Marketing Research initially published a study[227] in which they estimated that the total lifetime energy cost of a 2005 Prius was greater than that of aHummer H2. The study has been widely debunked: see for example, "Hummer versus Prius: 'Dust to Dust' Report Misleads the Media and Public with Bad Science".[228]
The Prius uses electric motors in the hybrid propulsion systems, powered by a high voltage battery in the rear of the car. There has been some public concern over whether the levels ofelectromagnetic field exposure within the cabin are higher than comparable cars, and what health effects those fields may present, popularized by a 2008The New York Times article.[229] Toyota[229] and several independent studies[230][231] have indicated that aside from a brief spike when accelerating, the electromagnetic fields within the Prius are no different from those of a conventional car and do not exceed theICNIRP[232] exposure guidelines.
A 2013 study by theMayo Clinic found that patients with implanted cardiac devices such aspacemakers anddefibrillators can safely drive or ride in hybrids orplug-in electric cars without risk ofelectromagnetic interference (EMI). The research was conducted using implantable devices from the three major manufacturers and a 2012 Toyota Prius hybrid. The study used 30 participants with implanted devices and measured electric and magnetic fields in six positions inside and outside the Prius, and each position was evaluated at different speeds.[233]
The Wall Street Journal reported in February 2007 on concerns that quiet cars like the Prius may pose a safety risk to pedestrians who rely on engine noise to sense the presence or location of moving vehicles.[234] Blind pedestrians are a primary concern, and theNational Federation of the Blind advocates audio emitters on hybrid vehicles,[235] but it has been argued that increased risks may also affect sighted pedestrians or bicyclists who are accustomed to aural cues from vehicles. However, silent vehicles are already relatively common, and there is also a lack of aural cues from vehicles that have a conventional internal combustion engine where engine noise has been reduced by noise-absorbing materials in the engine bay and noise-cancelling muffler systems. In July 2007, a spokesman for Toyota said the company is aware of the issue and is studying options.[236]
In 2010, Toyota released a device for the third-generation Prius meant to alert pedestrians of its proximity.[237] Japan issued guidelines for such warning devices in January 2010 and the US approved legislation in December 2010.[238][239] Models equipped withautomatically activated systems include all 2012 and latermodel year Prius family vehicles that have been introduced in the United States, including thestandard Prius, thePrius v, thePrius c and theToyota Prius Plug-in Hybrid.[240][241] The warning sound is activated when the car is traveling at less than 15 mph (24 km/h) and cannot be manually turned off.[242]
In the UK, theAdvertising Standards Authority, an independent body charged with policing the rules of the advertising industry, ruled that a television advert for the Toyota Prius should not be broadcast again in the same form, having breached rules concerning misleading advertising. The advertisement stated that the Prius "emits up to one tonne less CO2 per year", while on-screen text included "1 tonne of CO2 less than an equivalent family vehicle with a diesel engine. Average calculated on 20,000 km a year." Points of contention were the vehicles chosen for comparison, whether "'up to' one tonne less" adequately communicated that reductions could be lower, and whether the distance used was appropriate: 20,000 km (12,000 miles) per year is around a US car's average annual driving distance, while a UK car's is 13,440 km (8,350 miles).[243]
The large number of Prius-owning progressive celebrities in 2002 promptedThe Washington Post to dub hybrids "Hollywood's latest politically correct status symbol".[244] Conservatives called "Prius Patriots" also drive the cars because they want to contribute to reducing US dependence on foreign oil.[245] A 2007San Francisco Chronicle article said "Prius Progressives" were becoming an archetype, with American conservative commentatorRush Limbaugh opining that "these liberals think they're ahead of the game on these things, and they're just suckers".[246]
In July 2007,The New York Times published an article using data from CNW Marketing Research finding that 57% of Prius buyers said their main reason for buying was that "it makes a statement about me", while just 37% cited fuel economy as a prime motivator.[247] Shortly afterwardsWashington Post columnistRobert Samuelson coined the term "Prius politics" to describe a situation where the driver's desire to "show off" is a stronger motivator than the desire to curbgreenhouse gas emissions.[248] Some conservatives promote the use of the Toyota Prius and other hybrid cars. For example, Jim Road fromWhat Would Jesus Drive? encouraged people to drive hybrid cars because of the damage that large SUVs and faster cars can do to others.[249]
FormerCentral Intelligence Agency (CIA) chiefR. James Woolsey, Jr. drives a Prius because of its low fuel consumption. Woolsey noted the volatility of the Middle East, coupled with anti-US sentiment in much of the region. Noting that the high percentage of oil drilled in the Middle East gives vast profits to Middle Eastern regimes, Woolsey believes that it is a patriotic obligation to drive more efficient vehicles. In aMotor Trend magazine article, Woolsey stated that those oil profits find their way to terrorist groups likeal-Qaeda, meaning that Americans who buy inefficient vehicles would, in effect, be indirectly funding terrorism. "We're paying for both sides in this war, and that's not a good long-term strategy," said Woolsey. "I have a bumper sticker on the back of my Prius that reads, 'Bin Laden hates this car.'"[250]
Adriverless version of the Prius was one of six cars to finish the 2007DARPA Urban Challenge.[251]
A racing version of the Prius was unveiled by Toyota in 2013. This racing Prius replaces the 1.8-litre Atkinson-cycle engine with a 3.4-litre V8 RV8KLM engine which is mid-mounted in the car. The hybrid drivetrain of the car's production Hybrid Synergy Drive is retained but with a larger lithium-ion battery.[252] The RV8KLM is in fact the same engine featured in multiple Le Mans Prototypes such as theLola B12/60 andRebellion R-One. The car took classpole position[253] and finished sixth at the2012 Fuji GT 500km.[254]
For 2019 a new version of the Prius was unveiled. Based on the Prius PHV GR Sport, this version of the Prius was powered by a 5.4L2UR-GSE V8 mounted in the front of the car. The hybrid system was retained for this version of the car but only on the #31 car. The Prius was retired from Super GT competition after the2022 Super GT Series.[255]
There have been a number of governments with incentives intended to encourage hybrid car sales. In some countries, including the US and Canada, some rebate incentives have been exhausted, while other countries such as the United Kingdom, Sweden, Belgium, and the Netherlands have various or alternative incentives to purchasing a hybrid vehicle.
Several US companies offer employees incentives.Bank of America will reimburseUS$3,000 on the purchase of new hybrid vehicles to full- and part-time associates working more than 20 hours per week.[256]Google,[257] software companyHyperion Solutions,[258] and organic food and drink producerClif Bar & Co[256] offer employees aUS$5,000 credit toward their purchase of certain hybrid vehicles including the Prius. Integrated Archive Systems, a Palo Alto IT company, offers aUS$10,000 subsidy toward the purchase of hybrid vehicles to full-time employees employed more than one year.[256]
Travelers Companies, a large insurance company, offers hybrid owners a 10% discount on auto insurance in most US states.[259] TheFarmers Insurance Group offers a similar discount of up to 10% in most US states.[256]
In June 2015, the Prius started use as a general purpose patrol car of theNational Police of Ukraine. In return for Ukrainian emissions permits under theKyoto Protocol, 1,568 cars were supplied by Japan.[260]
ThePhilippine National Police is one of the agency beneficiaries of the Toyota Prius (2017 model) hybrid cars donated by the Department of Energy (DOE) through the Japan’s Non-Project Grant Aid (NPGA) as part of the DOE’s campaign to promote energy efficiency and clean air across the country. Forty-five units of the vehicle will be given to Police Regional Office 8 particularly the areas which were affected byTyphoon Yolanda in 2013 to support the socio-economic recovery of the communities and provide additional police mobility. The official turnover of donation led by Ambassador Kazuhide Ishikawa, Embassy of Japan to the Philippines, and Department of Energy Secretary Alfonso Cusi was held on 19 May 2017 at the DOE Sunken Garden in Taguig where representatives of the agency beneficiaries received the key replicas.[261]
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.The Prius family accounts for 61% of Toyota's total global cumulative hybrid car sales: 6.115 million units, consisting of Prius liftback: 3.9846 million; Aqua, Prius c: 1.3801 million; Prius α, Prius v, Prius +: 614,700; and Prius PHV: 79,300.
