Available in both 2-door coupe and convertible versions, both with 2+2 seating, BMW’s 6 Series is powered by a 4.8-liter, 360 horsepower V-8 mated to a new 6-speed sport automatic transmission. The high-performance M6 combines a 500 horsepower V-10 and a 7-speed sequential manual gearbox. 0 to 60 mph acceleration takes just 4.6 seconds and top speed is electronically limited to 155 mph. High-tech options include BMW night vision thermal imaging and a head-up display projecting information on to the windscreen.
