2013 Mercedes-Benz CLS63 AMG

The CLS63 AMG uses a seven-speed transmission that transfers power to the rear wheels, and 60 mph arrives in just under 4.5 seconds. The engine is relatively efficient for its size and power, achieving 16 mpg city and 25 mpg highway. (Expect less from cars with the Performance package.) Triple-spoke nineteen inch wheels come as standard; an optional five-spoke wheel can be had for an additional $1,790.

A sharply-appointed interior features leather seats, brushed aluminum trim, a Harmon/Kardon 14-speaker sound system and a hands-free Bluetooth interface as standard equipment. For an additional cost, Mercedes also offers a multicontour driver's seat with extra power controls for the lumbar, shoulder and side bolsters, as well as a massage feature. Sleek exterior styling with sweeping lines embody the "four-door coupe" look for which the CLS is famous—but, while attractive, the roofline's extreme rake does limit rear headroom.
