:buttsex: BMW’s Heralded 4.4-liter V8 Offers Performance That Matches Its Style The 4.4-liter V8 engine already well known from the BMW 745i ensures optimal power and torque over the entire engine speed range. Featuring fully variable VALVETRONIC valve control, the engine develops 325-horsepower and 330 lb-ft of powerful torque at 3,600 rpm. This enables the new 6 Series Coupe to effortlessly reach its top speed of 149 mph(electronically limited). Acceleration is equally good, with the BMW 645Ci covering the sprint from 0-60 mph in well under six seconds. To convey this refined power to the rear wheels, BMW offers the driving enthusiast the widest range of possibilities—three different six-speed transmissions: -*Six-speed manual -*Six-speed STEPTRONIC automatic -*Six-speed Sequential Manual Gearbox (SMG) featuring both a gearshift lever and shift paddles on the steering wheel, like in Formula One race cars The new 6 Series Coupe comes standard with BMW Driving Dynamic Control (DDC). First seen on the Z4 Roadster, this feature gives the engine an even more spontaneous reaction to the gas pedal, influences steering in relation to road speed, allows the automatic or SMG transmission to hold gears longer, and provides faster SMG shifts - all at the touch of a button.
