BMW 6 Series 
The 6 Series defines what grand touring is for BMW. This majestic two- or four-door coupe benefits from xDrive all-wheel traction. However, the sporty M6 sends all of its 560 horses to the rear wheels via a six-speed manual or seven-speed automatic. The 640i (315-hp six-cylinder) and 650i (455-hp V8) versions share an eight-speed automatic, along with the exclusive B6 Alpina Gran Coupe (540-hp V8), the most opulent and grand 6 Series.
