2013 BMW 6 Series 650i

The 6 Series is BMW's grand touring coupe, convertible, and four-door Gran Coupe, aimed at buyers who want luxury and style over pure practicality. It's a car that feels at home on long highways, with a hushed cabin and a ride that soaks up miles effortlessly. Despite its size, the 6 Series corners with surprising composure, though the steering can feel a bit numb at times. Inside, you get a beautifully crafted cabin with high-quality materials and comfortable seats, but rear legroom is tight in the coupe and convertible. The 650i sits above the 640i in the 6 Series lineup, swapping the inline-six for a V8 and adding more standard equipment. Its 4.4L V8 makes 445 horsepower and 480 lb-ft of torque, routed through a eight-speed automatic to the rear-wheel drive, which gives it effortless highway passing power. EPA estimates 19 mpg combined for this coupe, which is reasonable given the V8's performance.
