BMW 6-series

 The 6-series is the BMW’s most exclusive coupe and convertible offering, and enters the 2014 model year with minor refinements. The 6-series is available with either a 3.0-liter inline-six (640i) or 4.4-liter V-8 (650i). The 640i has a single turbo while the 650i has two; both engines mate to an eight-speed automatic. Rear-wheel drive is standard, while all-wheel drive is offered on both. There is also an M Sport package with even more upscale interior and exterior accents for extra bling.
