What Changed

The second-generation 6-series has grown appreciably longer and wider. The 650i convertible retains its soft-top convertible and four-passenger seating. Power is provided by either a 3.0L inline 6 (640i) or a 4.4l V8 (650i) rated at 400-bhp. An eight-speed automatic is standard on the 640i. The 650i offers a six-speed manual in addition to the automatic. The 6-Series range now includes an all-wheel-drive model (650i xDrive). The new interior features a standard 10.2-inch center screen designed to minimize glare.
