The motor is expected to appear in the 2007 BMW 335i and 2007 BMW 335ci (coupe). The engine has an output of 306 horsepower and maximum torque of 295 lbs.-ft (400 Nm). BMW said it has already tested a 3-Series sedan with the engine, and achieved a 0-62mph time of 5.7 seconds. BMW said the engine is relatively lightweight — about 70kg less than its 4.0-liter V8 engine. According to the automaker, the 3.0-liter engine has little or no turbo lag, thanks to two small turbos instead of one large one. Maximum torque is achieved between 1500 and 5800 rpm
