Interior

The first generation of the BMW 1 Series consists of the BMW E81 (3-door hatchback), BMW E82 (coupe), BMW E87 (5-door hatchback) and BMW 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 the 3 Series Compact as the entry-level models of the BMW range.

The chassis has an aluminum multi-link suspension, and a rear-wheel drive layout with a longitudinally-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-cylinder naturally 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 the 1 Series M Coupé which was powered by the BMW 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 the BMW M2.

Following the introduction of the F20/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 the F22/F23 2 Series models.

Development and launch

[edit]

Initially, BMW considered adopting the Rover R30 design program into the upcoming 1 Series; however, it was eventually decided to develop the E8x alongside the E90 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 director Chris Bangle,[7] At the 2002 Geneva Motor Show, the CS1 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 the Paris 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 the on-board diagnostics (OBD) connection.[14][15] This security flaw was later patched, for both existing vehicles and new cars produced since.[16]

Model year changes

Pre-facelift E87
Post-facelift E87

2007

[edit]

In March 2007, the E87 five-door hatchback received a facelift (also called LCI).[17] Changes included the N43 four-cylinder engine replacing the N45 and N46 engines, various changes to improve fuel economy (marketed as EfficientDynamics), 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]

2010

[edit]

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, the N55 engine replaced the N54. 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]

5-door hatchback (E87)

[edit]

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]

3-door hatchback (E81)

[edit]

The E81 three-door hatchback models were produced from July 2007 until 2012.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]

2-door coupe (E82)

[edit]

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 the Frankfurt 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.

2-door convertible (E88)

[edit]

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 the E93 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 the N54 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 the N55 single-turbo 3.0-litre engine with a 6-speed manual or a 7-speed dual-clutch transmission.[51][52] The differential 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 litre BMW 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 the N52 3.0-litre naturally aspirated engine[56][57] and transmission choices were a 6-speed manual or a 6-speed automatic.[58][59]

Transmissions

[edit]

In early 2006, the 5-speed manual transmission was phased out in favour of the 6-speed Getrag GS6 gearbox.

Several 6-speed automatic transmissions were used- the ZF 6HP for the 135i, GM 6L50 for the 128i, and GM 6L45 for 116i.[60] A 7-speed Getrag dual-clutch transmission ("DCT") was available for the 135i model from 2010.[61]

BMW Performance upgrades

[edit]

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.

Special editions

[edit]

1 Series M Coupé

[edit]
1M Coupe

The BMW 1 Series M Coupé (often referred to as the "1M") is the high-performance model of the E82 coupe range, sold under the BMW M performance sub-brand. While BMW naming convention would have called the car the "M1", an alternate name was chosen to avoid confusion with the BMW M1 supercar from the 1970's.[63]

At the 2007 Tokyo Auto Show, BMW unveiled the 1 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 the S63 V8 which debuted in the X6M). The BMW N54 fitted to the 1M was originally being used in the E89 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 rear track 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 the Evo Magazine 2011 Car of the Year awards.[73] It also featured on Top Gear on 26 June 2011 and recorded a time of 1:25.0 around the Top Gear test track under damp conditions[74][75] and received "Richard Hammond's Car of the Year 2011" award in the Top Gear magazine.[76]

ActiveE electric car trial

[edit]
Main article: BMW ActiveE

The BMW ActiveE was an electric 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 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.

BMW 135is (United States and Canada)

[edit]

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 generation F20 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 the N55 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]

Production and sales

[edit]

The 1 Series was built in Regensburg and Leipzig, Germany.

The E8x accounted for nearly one-fifth of the total BMW sales in 2008.[85]

BMW 1 Series (E87)

View on Grokipedia
from Grokipedia
The BMW 1 Series (E87) is the designation for the first-generation BMW 1 Series, a line of subcompact executive hatchback automobiles introduced by the German automaker BMW in 2004 as its entry into the premium compact segment, featuring rear-wheel drive, a sporty chassis, and a range of inline-four and inline-six engines producing between 115 and 340 horsepower. The E87 specifically refers to the five-door hatchback body style, which debuted at the Paris Motor Show in September 2004 and entered production that autumn, marking BMW's first standalone model in the small car class after the 3 Series Compact. With a wheelbase of 2.66 meters for optimal weight distribution (50:50) and dimensions emphasizing agility—4.23 meters long and 1.75 meters wide—the E87 combined premium interior materials, advanced suspension (including an aluminum front axle and multi-link rear), and efficient engineering like a low drag coefficient of 0.29. Initial engine lineup included petrol variants such as the 116i with a 1.6-liter four-cylinder (115 hp, 150 Nm , 0-100 km/h in 10.8 seconds) and the 120i with a 2.0-liter four-cylinder (150 hp, 200 Nm, 0-100 km/h in 8.7 seconds), alongside diesels like the 118d (2.0-liter, 122 hp, 280 Nm, 50.4 combined) and 120d (163 hp, 340 Nm, 49.6 ), all paired with five- or six-speed manuals and optional automatics, while meeting Euro 4 emissions standards. Subsequent expansions added higher-output options, including the 130i with a 3.0-liter inline-six (265 hp) in 2005 and the performance-oriented 1 Series M Coupé (340 hp twin-turbo inline-six) in 2011, broadening the lineup to appeal to enthusiasts seeking dynamic driving in a compact package. The model range grew to include the three-door (E81) from 2007, two-door coupé (E82) and (E88) from 2008, all sharing the E87's platform and rear-drive architecture for superior handling compared to front-wheel-drive rivals. A mid-cycle facelift in March 2007 refreshed the E87 with updated styling—sharper headlights with daytime-running light rings, revised front/rear bumpers for a more aggressive look, and new wheel designs—alongside mechanical enhancements like Euro 5-compliant engines, the introduction of EfficientDynamics technologies (including auto start-stop and brake energy regeneration), and improved interior tech such as optional iDrive navigation. Production of the variants continued until 2011, with the coupé and extending to 2013, after which the 1 Series was partially succeeded by the 2 Series for two-door models; over its run, the E8x family emphasized BMW's core values of performance, premium quality, and innovative efficiency in the compact premium market.

Overview

Introduction

The BMW 1 Series (E87) represents the first generation of BMW's subcompact lineup, introduced in 2004 as a compact model emphasizing rear-wheel-drive dynamics and sporty performance in an accessible package. Production of the variants spanned 2004 to 2011, while the coupé and convertible models extended until 2013, making the overall run from 2004 to 2013. This generation succeeded the (E46) and introduced a dedicated 1 Series badge to the brand's portfolio. Available in multiple body styles, the lineup included the E81 3-door , E87 5-door , E82 2-door coupé, and E88 , all built on a front-engine, rear-wheel-drive platform that delivered near-perfect 50:50 weight distribution for balanced handling. The design prioritized driving engagement in the compact executive segment, sharing key platform components with the contemporaneous E90 3 Series. Key dimensions included a of 2,660 mm, overall lengths varying from 4,227 mm (pre-facelift hatchbacks) to 4,360 mm (coupé and ), with post-facelift hatchbacks at 4,239 mm, and curb weights ranging from 1,245 kg to 1,540 kg depending on configuration and engine. The hatchback models were succeeded by the F20 and F21 generations, while the coupé and gave way to the F22 and F23.

Platform and design

The BMW 1 Series (E87) utilized a dedicated compact platform derived from the architecture of the contemporaneous E90 3 Series, incorporating significant shared components such as the front suspension, rear multi-link setup, and elements of the to leverage while adapting for a smaller . This engineering approach allowed for a steel monocoque chassis construction that emphasized structural rigidity and handling precision, with the longitudinally mounted positioned far back to achieve a near-perfect 50:50 in four-cylinder variants, enhancing balance and dynamic .

Adult occupant protection showed good results in side impacts where the structure provided maximum protection to the head, chest, and abdomen. The frontal offset test initially showed high chest loads for the driver, but a retest following refinements achieved adequate protection overall, aided by a stable passenger compartment with minimal distortion. In parallel, the Australasian ANCAP rating for the 2004 116i five-door hatch also awarded , with an overall score of 33.37 out of 37 points. Frontal offset protection reached 13.77 out of 16, while side impact performance was excellent at 15.60 out of 16, including full points in the pole test. The rear-wheel-drive layout contributed to superior side impact absorption through balanced 50:50 , though it presented challenges in managing energy deformation during frontal offset tests due to the longitudinally mounted . Standard safety equipment across models included six airbags—dual front, front side, and curtain airbags covering front and rear—as well as (ABS), and (ESC). The reinforced passenger cell featured a high-strength safety cage designed to maintain integrity during collisions, complemented by belt pretensioners and load limiters. Criticisms centered on pedestrian protection, which scored poorly in both tests: poor in ANCAP and just 2 points in , described as extremely poor due to the stiff bonnet leading edge and lack of energy-absorbing features. No significant updates were implemented for the facelift, which focused primarily on styling and efficiency enhancements rather than structural or active revisions.

Emissions and efficiency

The BMW 1 Series (E87) featured a range of petrol and diesel engines with varying fuel economy and CO2 emissions, reflecting the era's standards under the New European Driving Cycle (NEDC). Petrol variants generally achieved combined fuel consumption between 6.0 and 9.5 L/100 km, with CO2 outputs ranging from 143 to 225 g/km. For instance, the high-performance 130i model emitted 199 g/km of CO2 in its post-facelift configuration. Although official NEDC combined figures for petrol models typically ranged from 7 to 8 L/100 km, real-world fuel consumption reported by owners was generally higher due to factors such as traffic conditions, driving style, and vehicle load. For the post-facelift 118i (143 hp), user-reported averages included approximately 8.3 L/100 km from Fuelly data and 8.7 L/100 km from Honest John, with mixed driving often in the 8-9 L/100 km range. The 116i tended to achieve slightly lower figures of 7-9 L/100 km. City driving frequently exceeded 10 L/100 km, while highway consumption could be as low as 6-7 L/100 km. Diesel engines in the E87 lineup offered superior , with combined consumption typically from 4.6 to 5.7 L/100 km and CO2 emissions between 119 and 152 g/km. The post-facelift 120d, equipped with a 2.0-liter producing 177 hp, achieved 5.0 L/100 km and 125 g/km CO2, benefiting from refined turbocharging and lower-friction components. BMW introduced its EfficientDynamics package on the E87 with the 2007 facelift, incorporating technologies like brake energy regeneration and optimized aerodynamics to reduce fuel use and emissions across the lineup. A key feature was the optional from late 2007, which shut off the engine during idle to cut urban fuel consumption by up to 5%; this evolved into fully automatic operation by the 2011 model year update. Diesel models further benefited from BluePerformance enhancements, including particulate filters and precursors that lowered emissions while maintaining efficiency. The E87 also served as the basis for the ActiveE electric prototype in 2009, a demonstration vehicle with a 170 hp and pack that delivered zero tailpipe emissions during its field trials, providing key insights into battery integration and that shaped BMW's subsequent development.

Production and sales

Manufacturing

The BMW 1 Series (E87) hatchback models, including the 5-door (E87) and 3-door (E81) variants, were produced at the BMW Group Plant Leipzig in Germany from 2004 to 2011. The coupe (E82) and convertible (E88) body styles were manufactured at the BMW Group Plant Regensburg in Germany starting in 2007 and continuing until 2013. Production at Leipzig utilized modular assembly lines shared with the contemporaneous E90 3 Series, enabling efficient and flexible body style integration on the same infrastructure. The plant achieved a peak daily output of up to 700 units during the E87 era, supporting high-volume manufacturing while maintaining quality standards for rear-wheel-drive compact cars. By April 2010, cumulative production across and had exceeded 1 million units for the 1 Series lineup, with Leipzig contributing over 662,000 vehicles since its 2005 launch. The Leipzig facility's advanced flexible production capabilities allowed for a seamless transition to the successor F20-generation 1 Series in 2011, with minimal downtime as lines were reconfigured to accommodate the new model without halting overall operations. Total output for the E8x generation across all body variants reached approximately 1.1 million units by the end of production in 2013.

Sales figures

The BMW 1 Series (E87) recorded its initial sales in 2004, with 39,247 units sold globally following its launch. grew rapidly in subsequent years, reaching a peak of 225,095 units in 2008, which represented nearly one-fifth (approximately 18.7%) of BMW's total global vehicle that year. By 2012, sales had climbed to another high of 226,829 units, reflecting strong demand before the model's production transition. Note that figures from 2011 onward include sales of the successor F20 model.

Europe dominated regional sales, accounting for over 80% of global volume in peak years like , with 187,691 units sold there compared to much smaller figures elsewhere. In the United States, where the model was offered primarily as and convertibles (E82/E88) from onward, approximately 60,000 units were sold between and 2013, bolstered by variants like the 135i. Diesel engines drove much of the European success, particularly in markets favoring efficient powertrains, while coupe sales received a significant lift from the high-performance 135i trim. Following the end of new production in 2013, official sales data became limited, but the E87 maintained a robust legacy in the used vehicle market, especially in , where demand for well-preserved examples persisted into the 2020s.

Market reception

The BMW 1 Series (E87) received widespread praise from automotive critics for its exceptional handling and engaging driving dynamics, particularly in its rear-wheel-drive layout that delivered precise and balanced responses in the compact segment. In a 2005 review, Top Gear highlighted the model's nimble cornering and driver-focused character, dubbing it a standout "driver's car" despite its practicality. However, reviewers frequently criticized the E87 for its firm ride quality, which could feel harsh over uneven surfaces due to stiff suspension and run-flat tires, as well as limited rear passenger space that made it less family-friendly than rivals like the . The model garnered notable recognition early in its lifecycle, finishing as a finalist in the 2005 World Car of the Year awards with strong scores in merit (7.2) and safety/significance (7.4), though it was ultimately outpaced by the Audi A6. The high-performance 1M Coupé variant, introduced in 2011, was particularly lauded for delivering M3-like acceleration and handling in a more compact package, with its inline-six engine providing real-world speed advantages over the E90 M3 through superior delivery and a squat, agile chassis. The E87's legacy endures as a pivotal model in BMW's strategy for compact rear-wheel-drive vehicles, marking the brand's first foray into premium hot hatches and influencing subsequent generations with its emphasis on driving purity over outright space efficiency. A unique cultural touchstone came from a 2005 German advertising campaign featuring , which humorously showcased the car's "joy" of driving and became an iconic promotion for the lineup. As of 2025, the E87's reputation for reliability—bolstered by durable engines like the N52 inline-six—has helped maintain used values at 40–60% of original MSRP (around $25,000–$30,000 when new), with average market prices hovering near $10,000–$15,000 for well-kept examples. This positions it as the symbolic endpoint of BMW's internal-combustion-engine compact rear-drive era, just as the brand shifts toward front-wheel-drive and electric platforms in later 1 Series iterations. Sales peaked in around 2008, underscoring its commercial success amid these transitions.
