The BMW E81/E82/E87/E88 is the first generation of the BMW 1 Series range of small hatchback, coupe and convertible cars, which were produced from 2004 to 2013. It replaced the 3 Series Compact as the smallest and least expensive vehicle in the BMW range. The body styles of the range are:
The engines available were four-cylinder diesel and four- and six-cylinder petrol, in both naturally aspirated and turbocharged forms. Unlike most hatchback competitors, the E81/E82/E87/E88 uses rear-wheel drive (instead of front-wheel drive).
The 1 Series accounted for nearly one-fifth of the total BMW sales in 2008.
Initially, BMW considered adopting the Rover R30 design program into the upcoming 1 Series, however it was eventually decided to develop the 1 Series alongside the E90 3 Series. The E81/E82/E87/E88 shares approximately 60% of components with the E90, including front and rear suspension, structure, chassis, powertrain, hardware and electronic elements.
The 1 Series was launched globally in September 2004 as the E87 five-door hatchback.
The E81 three-door hatchback models were produced from July 2007 until 2012.
As per the five-door body style, the model range consisted of the 116i, 116d, 118i, 118d, 120i, 120d, 123d and 130i. The overall length is the same as the five-door models, and the kerb weight is 10 kg (22 lb) lighter.
The model range consisted of the 118d, 118i, 120i, 120d, 123d, 125i, 128i, 135i and the 1 Series M Coupé. In North America, the E82 went on sale in October 2007 with the 128i and the 135i models. 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 and 135i.
The E88 uses a fabric roof (unlike the E93 3 Series convertible, which uses a folding metal roof).
In early 2006, the 5-speed manual transmission was phased out in favour of the 6-speed gearbox.

In most countries, the 135i is the top model of the coupe and convertible range (excluding the limited production 1M Coupe). 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. From 2010, the 135i engine was upgraded to the N55 single-turbo 3.0 litre engine with a 6-speed manual or a 7-speed dual-clutch transmission. 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. The 135i brakes are 6-piston front calipers and 2-piston rear calipers, with disk sizes of 338 mm and 324 mm respectively.
The 135is coupe and convertible model was sold from 2013 in the United States and Canada (in other markets, the next generation F20 1 Series had replaced the E82/E88 by this stage). It is powered by an upgraded version of the N55 engine which produces 322 bhp (240 kW) and 317 lb⋅ft (430 N⋅m). Other upgrades include sports suspension, an M Sport body kit, and 18-inch wheels. Transmission options were - as per the 135i - a 6-speed manual of a 7-speed dual-clutch transmission.
The 130i is the top model of the E81/E87 hatchback range and was released in September 2004. It is powered by the N52 3.0 litre naturally aspirated engine and transmission choices were a 6-speed manual or a 6-speed automatic.

The BMW 1 Series M Coupe ("1M Coupe") is a high-performance version of the BMW 1 Series Coupe, developed by BMW's motorsport branch BMW M. While BMW naming convention would have called the car the "M1", the name "BMW 1 Series M" was used instead, to avoid confusion with the original BMW M1.
At the 2007 Tokyo Auto Show, BMW unveiled the "BMW 1 Series tii Concept", which was thought to be a preview of the M version of the 1 Series. However, the eventual M model appeared four years later and with significant differences, such as a six-cylinders instead of four. BMW officially announced the making of the M variant of the BMW 1-Series Coupé in December 2010.
The 1M coupe was BMW M's second turbocharged engine (after the S63 V8 which debuted in the X6M). Since the 1M Coupe's N54 engine was also used in the E89 BMW Z4 sDrive35is, the 1M Coupe is only the second M model, after the Z8 and E39 M5's shared S62, to use an engine shared with non-M models. The outputs for this engine are 250 kW (335 bhp) at 5900 rpm and 450 N⋅m (332 lb⋅ft) from 1,500 to 4,500 rpm. An additional 50 N⋅m (37 lb⋅ft) is produced during overboost taking overall peak torque to 500 N⋅m (369 lb⋅ft). The only available drivetrain is a six-speed manual gearbox with an M limited slip differential.
The 1M Coupe placed third in Evo Magazine's 2011 Car of the Year (eCOTY) awards. 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. and received "Richard Hammond's Car of the Year 2011" award in the Top Gear magazine.
In 2012, 1 Series vehicles were stolen by programming a blank key fob to start the car through the on-board diagnostics (OBD) connection. The primary causes of this vulnerability lie in the lack of appropriate authentication and authorization in the OBD specifications, which rely largely on security through obscurity. BMW offered all owners a free fix through a software update, and all newer vehicles have upgraded software that fixed this vulnerability.
The BMW ActiveE is a demonstration electric car based on the E82 coupe. It is the second vehicle after the Mini E to be developed under BMW Group's Project i. The electric drive system is the latest addition to BMW's EfficientDynamics program. The US Environmental Protection Agency official range is 151 kilometres (94 mi), with an energy consumption of 33 kW·h/100 miles, and the agency rated the ActiveE's combined fuel economy at 2.3L/100 km (102 miles per gallon gasoline equivalent).
Deliveries of the ActiveE for field testing in the U.S. began in January 2012, after the Mini E trial ended. A total of 1,100 vehicles were produced participate in the program worldwide, with 700 allocated for the U.S. trial and 35 for a trial in China.
In March 2007, the E87 five-door hatchback received a facelift (also called LCI). 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.
In May 2007, the E81 three-door hatchback models were released.
In 2011, 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. For the 135i model, the N55 engine replaced the N54. Even though many engines are 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.
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. In the United States, the 1 Series Coupé was marketed as a successor to the BMW 2002.
In 2006, a BMW 120d modified with a BMW customer racing kit entered by "Schubert Motors" placed 5th at the Nurburgring 24 Hours in a field of 220 cars.
