The redesigned 6 Series is still a grand touring two-door coupe or convertible, based on the 5 Series. It is longer and wider than the old car, with a lower overall height. Power comes from a 315-hp turbocharged six-cylinder or a 4.4-liter, 400-hp V8 mated to either an eight-speed automatic or a six-speed manual. The optional Integral Active Steering turns the front and rear wheels. BMW claims that improves high-speed stability as well as low-speed parking lot maneuvers. All-wheel drive and a more powerful M version are available.
