Spy shots of the new BMW 3-Series Coupe are popping up all over the place, and now Autoweek is providing us with several interesting details in advance of next week's Geneva launch. The new Coupe, built on the sedan platform, replaces the previous Coupe after a seven year run.

The car is larger than before but to keep weight down, aluminum is used in the front and rear suspension. It will be one of the first BMWs to use an advanced twin-turbo 3.0-liter inline six. To be introduced in a range-topping 335Ci model, it gets new direct injection technology, bettering today's naturally aspirated 3.0-liter inline six by 41 hp at 306 hp.

Inside, the cabin adheres closely to the 3 Series sedan's, with what one high-ranking BMW insider described to Autoweek as "a modern furniture look." The double binnacle dashboard housing the instruments is accompanied by a color monitor that works in tandem with iDrive.
