Technical Data and Figures: 1 Series : 3 Series : 5 Series : 6 Series : 7 Series : 8 Series : Z1 : Z3 : Z4 : Z8

The engines available for BMW E81 and BMW E87 are basically the same as found in the E90 / E91, with exception for the 3.0 L inline-6, which is slightly modified to produce more power. For the 2008 model year, the 135i is powered by a twin-turbocharged 3.0-litre inline six-cylinder engine that produces 300 brake horsepower (BHP) and 300 ft·lbf of torque from 1,400 rpm. For the 135i Coupé, acceleration from 0–62 mph (0–100 km/h) is 5.4 seconds, and top speed is electronically limited to 155 mph. Fuel efficiency is increased to 30.7 mpg, an improvement of 18% compared to its predecessor.

Petrol Engines

Diesel Engines

The flagship of the 1-series range is the 135i with a 3-litre twin-turbo petrol engine, generating 302 bhp with its six cylinders. This model also comes with a modified M sports package as standard. The 135i comes with the world's first differential with double-helical ball bearings which have the advantage of running at an even lower operating temperature reached more quickly than before thanks to the reduction of fluid required in the differential. The 123d pumping 201 bhp heads up the range of diesels and is the first ever 4-cylinder diesel engine to come with sequential twin-turbo technology.
