BMW E87 / E81 / E82 / E88 (1 Series – 1st generation)



BMW E87 is the first-generation BMW 1 Series is a compact executive car produced by the German automaker BMW since 2004, when it replaced the BMW 3 Series Compact as the smallest and least expensive vehicle in the BMW range. The 3-door and 5-door hatchbacks were replaced by the F20 and F21 models in 2012, while the E82 coupé and E88 convertible variants were replaced by the 2 Series F22 and F23 in 2013.

Available in 3-door hatchback (model code E81), 5-door hatchback (E87), coupe (E82) and 2-door convertible (E88) body styles, the 1 Series features a rear-wheel drive chassis, 50:50 weight balance, longitudinally-mounted engine and aluminum multilink suspension as well as a range of petrol and diesel engines. The 1 Series accounted for nearly one-fifth of the total BMW sales in 2008.

BMW E87 History:

BMW E87 1 Series was developed alongside the E90 3 Series. Design work was done by Christopher Chapman in 2001, which was frozen for series production at the end of 2001. The 2002 CS1 Concept previewed the 1-Series design elements at the 2002 Geneva Motor Show.



BMW E87 1 Series was launched globally in Autumn 2004 and shares many structural, chassis, powertrain, hardware and electronic elements with the larger E90 3-Series. The model was started to provide a lower point of entry into the BMW range as the 3 Series moved gradually up-market. Initially launched as a five-door hatchback, a three-door version was also launched in July 2007.

The 1 Series Coupé (E82) was unveiled in Internationale Automobil-Ausstellung (IAA) 2007, which went on sale on 24 November 2007.

The 1 Series coupe (E82) and convertible (E88) went on sale in the United States and Canada for the 2008 model year was the 128i and the 135i in June 2007. Other countries received the 120i and 125i in both platforms. The convertible, unlike the 3 Series convertible, uses a soft-top instead of a folding hardtop.

The North American introduction of the coupe and cabriolet was during the second quarter of 2008, which was credited for helping BMW overtake Lexus as the top luxury brand.

The first-generation 1 series shares over 60% of components with the E90 3-Series including front and rear suspension.




In 2007 the 1 Series lineup expanded considerably with the introduction of a three-door hatchback, coupe and convertible body styles. There was also a mid-generational refresh as engines were upgraded and more fuel efficient, along with new bumpers and other exterior and interior updates.

In 2011, the coupé and cabriolet bodies gained a facelift. Exterior changes to the model were minor headlight and taillight revisions, new front/rear bumpers and minor revisions to the interior. The only new engine was the N55 which replaced the N54 twin-turbo, with power and torque output remaining the same. 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.


The 1 Series Coupé was marketed in the US as a successor to the BMW 2002, a two-door from the 1970s known for its light weight and relative high performance at the time and its long bonnet, slim cabin and short rear.



In the 1-series hatchback commercial, Kermit the Frog was shown driving a BMW 1 Series around in a desert making figure eights, showcasing the car’s agility.

Jeremy Clarkson and other journalists raised aesthetic complaints about the 1-series, adding at the end of his review for the Sunday Times ‘The 1-series is crap.’

Critical response has changed in recent years with the introduction of the Coupé, and convertible model – which have been described as ‘returning BMW to its roots’, and the 135i has been described as the successor of the original E30 M3 of the 1990. Clarkson himself awarded the 2008 model five stars, and had the following to say: ‘The 135 coupé is the best car BMW makes.’

The BMW 118d (not sold in North America) won the ‘World Green Car Award’ in 2008 as a performance-oriented car with CO2 emissions and fuel consumption comparable to Toyota Prius.


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, including the more powerful Porsche 911 GT3BMW M3 and Lamborghini Gallardo.


  • 116i: Four-cylinder petrol, available in 3-door hatchback and 5-door hatchback body styles. In early 2006 the 5-speed manual transmission was phased out in favor of the 6-speed gearbox available across the rest of the range.

  • 128i: 3.0L, six-cylinder petrol engine (N52: 230 HP), available in coupe and convertible body styles, limited to the North American market.
  • 130i: 3.0L, six-cylinder petrol engine (N52: 265 HP), available in 3-door hatchback and 5-door hatchback body styles.
  • 135i: BMW 135i in Alpine White with BMW Performance upgrades:

Six-cylinder turbocharged petrol, available in coupe and convertible body styles. According to the BMW website the 135i Coupé produces 302 hp (225 kW), and accelerates from 0–100 km/h (62 mph) in 5.3 seconds, however Car and Driver magazine recorded 4.7 seconds for 0-60 mph acceleration, and a quarter mile time of 13.3 seconds at 106 mph (171 km/h). Top speed is electronically limited to 250 km/h (155.3 mph). Fuel efficiency is increased to 30.7 mpg-US (7.7 L/100 km; 36.9 mpg-imp), an improvement of 18% compared to its predecessor.

2007-10 model year BMW 135i coupe/cabriolet models were equipped with the N54 biturbo inline-6 engine, mated to a six-speed manual or optional six-speed “Steptronic” automatic transmission. For the 2011 model year onwards, the powertrain was changed to the N55 single (twin-scroll) turbo inline-6(making the same horsepower and torque output, but with lower fuel consumption and quicker turbo responsiveness), paired to a six-speed manual or optional 7-speed dual-clutch transmission. The short-lived 1 Series M Coupe retained the N54 biturbo inline-6, albeit in a higher state of tune.

The differential fitted to the 135i is the first in the world to use double-helical ball bearings. These bearings operate at a lower operating temperature(which can be reached more quickly), due to the reduction of fluid required in the differential.

Special standard features of the 135i included adaptive xenon headlights, sport suspension settings, 18″ wheels, high-performance brake system (6 piston front calipers with 338mm discs, and 2 piston rear calipers with 324mm discs), and a new DSC program that improves acceleration out of corners.

  • 135is Coupé and Cabriolet: The BMW 135is was a tuned version of 135i’s:

N55 twin-scroll turbo straight six making 320 hp and 317 lb-ft of torque, increases of 20 and 17 versus a standard 135i. The 135is also receives an upgraded cooling system with a more-powerful radiator fan and an auxiliary radiator, plus a M Sport Body. The performance of the 135is is close to that of the limited-production 2011 BMW 1 Series M.

The BMW 135is (E82) coupe/cabriolet was sold only in Canada and the United States, as the European market received the next-generation 1 Series, the 2013 BMW M135i (F20) 3-door and 5-door hatchback. Despite the differences in chassis, both the 135is and M135i share the same engine, however for their optional automated transmissions the 135is has a 7-speed dual-clutch gearbox while the M135i has an 8-speed automatic.

Honest John reports on his website: “Coil and injector problems on later 4-cylinder petrol engines. Timing chain failures on N47 diesel engines becoming very common.” The latter complaint was the subject of a BBC ‘Watchdog’ Consumer program in June 2013. The cost of repair was then a little over £4,000. BMW responded by saying that it would consider claims involving cars older than 3 years where a full BMW service history was available.
