At the Detroit Auto Show 2010, BMW brought out an existing upgraded model, destined for the enthusiasts in the BMW community. The 2010 BMW 135i Coupe makes a transition from the several times award winning N54 six-cylinder twin-turbo engine to the newer, more efficient and equally powerful, N55.

The N55 powerplant uses the the innovation of twin-scroll technology and the integration of VALVETRONIC throttle-less intake technology.

This new engine promises even better throttle response and even more fuel efficiency. Thanks to VALVETRONIC, VANOS, and the twin-scroll turbocharger housing, peak torque is reached 100rpm earlier than with the previous engine, and engine boost response is improved across the entire engine speed range.


N55 develops maximum output of 300 hp at 5,800 rpm, with peak torque of 300 lb-ft available all the way from 1,200–5,000 rpm. The exciting part comes with the 7-speed Double-Clutch Transmission (DCT), the first time an option for the 1 Series Coupe and Convertible.

As we mentioned last week, the old school M3 shifting paddles make a comeback. The shift paddles now feature dedicated paddles for upshifting and down shifting. The driver now pulls the right paddle for upshifts and the left for down shifts.

A more detailed article on the N55 will follow in the next days. Enjoy our amazing photo gallery!
