| Successor | E81/E87:1 Series (F20/F21) E82/E88:2 Series (F22/F23) |
The first generation of theBMW 1 Series consists of theBMW E81 (3-door hatchback),BMW E82 (coupe),BMW E87 (5-door hatchback) andBMW E88 (convertible)compact cars. The E81/E82/E87/E88 generation was produced from 2004 until 2013 and is sometimes collectively referred to as the E8x. The E8x replaced the3 Series Compact as the entry-level models of the BMW range.
The chassis has an aluminummulti-link suspension, and arear-wheel drive layout with alongitudinally-mounted engine giving 50:50 weight balance, which was a rare configuration for a hatchback as most cars in this market segment use front-wheel drive. The engines available were four-cylinder turbo-diesel, four-cylindernaturally aspirated petrol, six-cylinder naturally aspirated petrol and six-cylinder turbocharged petrol (the latter only available on coupe and convertible models).[4]
The highest performance trim is the1 Series M Coupé which was powered by theBMW N54 turbocharged inline-six engine mated to a six-speed manual transmission. It was produced in only the coupe body style and is considered the predecessor to theBMW M2.
Following the introduction of theF20/F21 1 Series in 2011, the E81/E87 hatchback models began to be phased out, while the E82/E88 coupes and convertibles remained in production until 2013, when they were replaced by theF22/F23 2 Series models.
Initially, BMW considered adopting theRoverR30 design program into the upcoming 1 Series; however, it was eventually decided to develop the E8x alongside theE90 3 Series.[5] The E8x shares approximately 60% of components with the E90,[6] including front and rear suspension, structure, chassis, engines, drivetrain, hardware and electronic elements.
The 1 Series was developed under design directorChris Bangle,[7] At the 2002 Geneva Motor Show, theCS1 Concept previewed the 1 Series design.[8][9][10] with Christopher Chapman leading the exterior design for the hatchback models.[11]
The first 1 Series production models – in the E87 five-door hatchback body style – were launched at theParis Motor Show in September 2004.[12]
In May 2005, in a commercial for the 1 Series Hatchback,Kermit the Frog was shown driving a BMW 1 Series around in a desert making figure-eights, showcasing the car's agility.[13]
In 2012, a number of 1 Series vehicles were stolen in the United Kingdom, due to thieves programming a blank key fob to start the car through theon-board diagnostics (OBD) connection.[14][15] This security flaw was later patched, for both existing vehicles and new cars produced since.[16]

In March 2007, the E87 five-door hatchback received afacelift (also called LCI).[17] Changes included theN43 four-cylinder engine replacing theN45 andN46 engines, various changes to improve fuel economy (marketed asEfficientDynamics),electric power steering replacing the traditional hydraulic power steering, revised bumpers and interior changes.[18][19]
In May 2007, the E81 three-door hatchback models were released.
In November 2007, the E82 coupe models were released, followed by the E88 convertible models soon after.[20][21]
In 2010 (2011 Model Year), the E82 coupé and E88 convertible models received a facelift. Changes included headlights and taillight revisions, new front/rear bumpers and minor revisions to the interior.[22][23] For the 135i model, theN55 engine replaced theN54. Even though many engines are the same, the facelifted 1 Series fuel consumption is slightly higher in some models such as the 123d, and slightly lower in some models such as the 120i.[24]

Reviews of the 1 Series' exterior styling were mixed, with the unusual proportions of the hatchback model often receiving criticism.[25][26][27][28][29]
The 1 Series was launched globally in September 2004 as the E87 five-door hatchback.
The E87 was produced from 2004 until 2011,[30] with the model range consisting of the 116i, 116d, 118i, 118d, 120i, 120d, 123d and 130i. Kerb Weight: 1340 kg (2954 lbs.).[31][32]
The E81 three-door hatchback models were produced from July 2007 until 2012. It was designed before the 5 door hatchback, coupé and convertible versions (hence its lower e-number), but its introduction was delayed until 2007 when it was unveiled at the Frankfurt Motor Show.
As per the five-door body style, the model range consisted of the 116i, 116d, 118i, 118d, 120i, 120d, 123d and 130i.[33] The overall length is the same as the five-door models, and the kerb weight is 10 kg (22 lb) lighter.[34][35]
The 1 Series Coupé (E82) was designed before the 5 door hatchback and convertible versions (hence its lower e-number), but, like the 3-door hatchback, its introduction was delayed until 2007 when it was unveiled at theFrankfurt Motor Show[36][37] and went on sale on 24 November 2007.
The model range consisted of the 118d, 118i, 120i, 120d, 123d, 125i, 125se, 128i, 135i, 135is, and the M Coupé.[38] In North America, the E82 went on sale in October 2007 with the 128i and the 135i models.[39] The E82 was produced until August 2013.
The E88 convertible models were produced from 2007 until June 2013. The model range consisted of the 118d, 118i, 120i, 120d, 123d, 125i, 128i, 135i, and 135is.[40]
The E88 uses a fabric roof (unlike theE93 3 Series convertible, which uses a folding metal roof).

In most countries, the 135i is the top model of the E82/E88 coupe/convertible range (excluding the limited production 1M Coupe).[48] From 2007 to 2010, the 135i was powered by theN54 twin-turbo 3.0-litre engine with a 6-speed manual or a 6-speed automatic transmission.[49][50] From 2010, the 135i was upgraded to theN55 single-turbo 3.0-litre engine with a 6-speed manual or a 7-speeddual-clutch transmission.[51][52] Thedifferential fitted to the 135i uses double-helical ball bearings, which operate at a lower temperature and reach operating temperature quicker, due to a reduction of fluid required in the differential.[53] The 135i brakes are 6-piston front calipers and 2-piston rear calipers, with disk sizes of 338 mm and 324 mm respectively.[54]
Another E82/E88 coupe/convertible trim sold only in the United States and Canada was the 128i, which was powered by a 170 kW (228 hp) version of the 3.0 litreBMW N52 inline-6 engine.
The 130i is the top model of the E81/E87 hatchback range and was released in September 2004.[55] It is powered by theN52 3.0-litre naturally aspirated engine[56][57] and transmission choices were a 6-speed manual or a 6-speed automatic.[58][59]

In early 2006, the 5-speedmanual transmission was phased out in favour of the 6-speed Getrag GS6 gearbox.
Several 6-speed automatic transmissions were used- theZF 6HP for the 135i,GM 6L50 for the 128i, andGM 6L45 for 116i.[60] A 7-speed Getragdual-clutch transmission ("DCT") was available for the 135i model from 2010.[61]
BMW offered a "performance power kit" in two stages for the N55 engine. Stage 1 included an ECU remap with a power boost from 225 kW to 240 kW and 30Nm of extra torque – now peaking at 430Nm. If installed in an automatic 335i or 135i the torque peak is bumped up by another 20Nm to 450Nm.[62]Stage 2 added some additional engine cooling through an additional supplementary radiator and larger cooling fan.Other upgrade options included a modified rear bumper and performance rear muffler. These options were all included as standard on the US spec 135iS.

TheBMW 1 Series M Coupé (often referred to as the "1M") is the high-performance model of the E82 coupe range, sold under theBMW M performance sub-brand. While BMW naming convention would have called the car the "M1", an alternate name was chosen to avoid confusion with theBMW M1 supercar from the 1970's.[63]
At the2007 Tokyo Auto Show, BMW unveiled the1 Series tii Concept, which was thought to be a preview of the M version of the 1 Series.[64][65] However, the eventual 1M model appeared four years later and with significant differences, such as an engine with six-cylinders instead of four.[66]
The 1M was BMW M's second turbocharged engine (after theS63 V8 which debuted in the X6M). TheBMW N54 fitted to the 1M was originally being used in theE89 Z4 sDrive35is and has rated outputs of 250 kW (335 bhp) at 5,900 rpm and 450 N⋅m (332 lb⋅ft) from 1,500 to 4,500 rpm.[67] An additional 50 N⋅m (37 lb⋅ft) is produced during overboost taking overall peak torque to 500 N⋅m (369 lb⋅ft).[68] The sole transmission available was a six-speed manual.
The front and reartrack widths were widened by 74 mm (2.9 in) and 46 mm (1.8 in) respectively and a limited-slip differential was used.[69] As a result, the overall width is 1,803 mm (71.0 in).[68] The curb weight is 3,296 lb (1,495 kg).[70]
Initial plans were to limit production of the 1M Coupe to 2,700 units, but the final production total was 6,309.[71][72]
The 1M Coupe placed third in theEvo Magazine 2011 Car of the Year awards.[73] It also featured onTop Gear on 26 June 2011 and recorded a time of 1:25.0 around theTop Gear test track under damp conditions[74][75] and received "Richard Hammond's Car of the Year 2011" award in theTop Gear magazine.[76]
TheBMW ActiveE was anelectric car based on the E82 coupe that was produced in small quantities for demonstration and testing purposes.[77] The U.S. Environmental Protection Agency rated the range as 151 km (94 mi) and the energy consumption as 33 kW·h per 161 km (100 mi).[78] The cars were leased to customers for two years, following which they were taken off the road. A total of 1,100 vehicles were produced, with 700 of these being delivered to U.S. customers beginning in January 2012.[79][80]
In 2006, a BMW 120d modified with a BMW customer racing kit[81] entered by "Schubert Motors" placed 5th at the Nurburgring 24 Hours in a field of 220 cars.
Beric Lynton won the2014 Australian Production Car Championship driving a BMW 1M.
In 2019, the UK based 750 Motor Club introduced a one make mini endurance series using the 2004-2006 116i car. Modified from factory production specifications with a coil over suspension kit, reworked motorsport exhaust and re-programmed ECU the cars race in a 90-minute multiple driver format. For 2020, the series attracted regular grids of over 25 cars with more than 50 cars having been built by both privateers and professional teams.
The 135is coupe and convertible model was sold only for the 2013 model year in the United States and Canada. In other markets, the next generationF20 1 Series had replaced the E82/E88 by this stage, with the top-of-the-line M135i sharing the same engine as the 135is.[82]
The 135is is powered by an upgraded version of theN55 engine which produces 240 kW (322 hp) and 430 N⋅m (317 lb⋅ft), an additional 20 hp and 17 lb-ft of torque over the 135i. Other upgrades include sports suspension, an M Sport body kit, and 18-inch wheels.[83][84]
The 1 Series was built inRegensburg andLeipzig, Germany.
The E8x accounted for nearly one-fifth of the total BMW sales in 2008.[85]
