Sedan, but its 4.3-inch shorter wheelbase and slightly wider rear track dimension add an extra measure of...

Although the suspension is tuned more for control than pure comfort, the 650i is still a first-rate cruiser. The silky 360-horsepower V8 takes it from zero to 60 mph in just about 5.5 seconds, regardless of whether it's backed by the conventional six-speed manual, BMW's six-speed SMG (Sequential Manual Gearbox) or the six-speed automatic with Steptronic shift control.
