Starting with March 2010, the BMW 135i Coupe and Convertible models will be powered for the first time by the inline six cylinder gasoline engine combining TwinPower Turbo with High Precision Injection and Valvetronic.
The new engine, codename N55, made its debut in the BMW 535i GT and it will be seen across the BMW line-up, starting with the facelifted 3 Series Coupe and Convertible. The engine comes matted to the new seven gear double clutch transmission with sports automatic.
The Twin-Scroll engine continues to produce 306 horsepower and takes the Coupe from 0 to 62 mph in 5.2 seconds and the convertible in 5.5 seconds. These performance figures are not, however, taking a toll on the fuel consumption and the official numbers show 8.5 liter per 100 km respectively 8.6 liter per 100 km.
Inside, a new gear selector is featured for seven gear double clutch transmission with sports automatic.
This is most likely the latest update to the current 1 Series line-up, as we approach the launch of a new, redesigned model at the end 2011. But, before new models enter the market, BMW will send off the current design with a BMW M1 version based on the Coupe platform.
More on that, later this year.
