The Mercedes-Benz CLK-Class is the exciting lineup of coupes and convertibles from Mercedes-Benz, embracing a racy style and free spirit. First introduced in 1997, its subsequent redesigns included the first production of a V-6 engine, aggressive styling cues from the E-Class, and chassis components from the C-Class. For 2008, the CLK 350 comes standard with a sport suspension and 18-inch wheels, while the CLK 550 remains unchanged. A CLK 63 AMG - the Black Series - is available as a coupe. The CLK 63 benefits from extensive re-engineering, including modified suspension components, lightweight 19-inch wheels, and 14.2-inch brake discs clamped by multipiston AMG calipers.

The Mercedes-Benz CLK 350 coupe and convertible are equipped with a 268-horsepower, 3.5-liter, V-6 engine. A 382-horsepower, 5.5-liter V-8 powers the CLK 550 models. The CLK 63 AMG convertible has a V-8 producing 475 horsepower and 465 pound-feet of torque. The CLK 63 Black Series coupe receives AMG's prolific 6.2-liter, V-8 engine producing 500 horsepower. This coupe takes an estimated 4.1 seconds to go from zero to 60 mph. All models are coupled with a seven-speed automatic transmission with touch shift manual options. Fuel economy is 17/25 mpg (city/highway) on the CLK 350 coupe; 15/22 mpg on the CLK 550 coupe; 17/25 mpg on the CLK 350 convertible; and 15/21 mpg on the CLK 550 convertible. The CLK-Class offers confident and stable handling. The CLK 550 powered by the robust V-8 engine is a good blend of performance and sophistication. The CLK 63 has amazing capabilities but its supercar personality is marred by lackluster steering when compared to other cars of its class.

Coupe or convertible, the Mercedes-Benz CLK 350 has a sweeping beltline that gives the car its sleek and elegant profile. The CLK 550 coupe is sporty and pillar-less; the streamlined design hints at the powerful performance; rear windows recede fully, adding to the open-air feeling. The CLK 63 AMG features a distinctive front air dam and side skirts, different from the standard CLK. The CLK 63 AMG has a low stance and large fenders, inspired by Mercedes-Benz's race cars. The CLK models come fully loaded with luxurious, well-equipped cabins that seat four passengers; seats come with premium leather upholstery; the rear seat splits and folds, making it easier to load cargo into the trunk. The convertible features large side windows and a slim roof design that is easily lowered or raised at the press of a button. Standard amenities include a Harman Kardon Logic 7 system, tele aid emergency assistance system, dual-zone air conditioning with sun sensor, 10-way power front seats and rain-sensing wipers. The interior is spacious, sumptuous and elegant. Most control systems are easy and convenient for usage, but the center stack's Comand (cockpit management and data) interface remains a challenge and may take some time getting used to.

Standard safety features include driver and passenger front-impact air bags; door-mounted driver air bags; passenger side-impact air bags; curtain overhead air bags; seatbelt pretensioners; side-impact bars; panic alarm; and power adjustable head restraints. Mercedes's electronic stability program, anti-lock brakes with brake assist technology, daytime running lights and driveline traction control further enhance driving stability and safety.
