Mercedes-Benz CLS 63 AMG

Mercedes-Benz CLS 63 AMG


After making its fashion runway debut only three years ago as the world's first four-door coupe, the highly successful Mercedes-Benz CLS-Class is getting a facelift for the 2009 model year. An instant style icon from day one, the CLS coupe has spurred an automotive industry trend toward more eye-catching four-door cars - vehicles that blur the line between coupe and sedan.

The sleek new nose of the CLS is complemented by a more dramatic two-bar grill (replacing the original four-bar grill), with upper and lower mesh now finished in Atlas Grey. Larger outside mirrors now feature built-in arrow-shaped turn signals, and new dual-five-spoke 18-inch wheels make the car even more striking. A new rear bumper with trapezoidal dual exhaust pipes and arrow-shaped LED taillights complete the fresh look of the new model.

Opening the driver's door reveals a sportier three-spoke steering wheel and new gauges in white with silver backgrounds. And, a new COMAND display in the center console now incorporates Bluetooth for hands-free cell phone operation, a six-CD "stacker" unit and voice control of audio and phone.

Two Sleek Models for 2009

For the 2009 model year, the CLS line will include the CLS550, powered by a DOHC four-valve-per-cylinder V8 engine that produces 382-horsepower and 391 pound-feet of torque, and the high-performance CLS 63 AMG, fitted with a AMG-designed 6.2-liter V8 that produces 507 bhp and 465 lb-ft of torque.

A handsome, coupe-like car that boasts the comfort and convenience of four doors, the CLS line features sleek, sensuous exterior lines. Its large rear doors and spacious rear seats also represent tangible added value.

Those stylish contours continue throughout the interior, which is complemented by an abundance of leather and wood. Its three chronometer-type gauges and two LCD bar graphs in the instrument cluster are accented by chrome rings and more wood trim. Four-zone climate control regulates temperature separately for each front and rear seat. The rear passengers even have their own digital control panel for setting a desired temperature and adjusting airflow.

The COMAND color display screen uses one set of easy-to-use controls for the audio system (includes AM/FM/ weatherband and CD), standard satellite radio and optional features such as GPS satellite navigation. The system includes a full array of mobile communications functions when combined with the optional phone.

A standard harman/kardon Logic 7 digital surround sound system provides a luxurious listening experience.

AMG Racing Success Spawns High-Power Production Engine

The Mercedes-Benz CLS63 AMG is powered by one of the most powerful naturally aspirated production V8s ever, also the first engine developed entirely by AMG. Built almost completely from a high-strength silicon-aluminum alloy, the 6.3-liter features four valves per cylinder, double overhead camshafts with variable valve timing, bucket tappets (rather than rocker arms), an 11.3-to 1 compression ratio and a variable intake manifold.

Power is transmitted to the rear wheels of the CLS63 AMG via a seven-speed AMG Speedshift automatic transmission that can be shifted manually by either a conventional lever or Formula-1 style shift paddles on the AMG sport steering wheel. AMG Speedshift electronic control provides 35% faster gear shifts, and to give performance-minded drivers total control of shifting, the manual mode of AMG Speedshift doesn't make any automatic upshifts or downshifts - even at max engine speed or full load.

To make sure the CLS63 AMG stops as fast as it goes, giant vented and perforated disc brakes all around feature 14-inch discs and six-piston calipers up front and 13-inch discs with four-piston calipers at the rear. Staggered 19-inch wheels with 8 1 and 9 1 inch widths carry 255 / 35 tires in front and 285 / 30 at the rear.

A 186-MPH Option

The CLS63 AMG can be ordered with the optional performance package that allows a 186-mph top speed instead of the usual 155-mph speed limiter. Other features in the package include AMG Airmatic sport suspension, 19-inch alloy wheels, larger front discs (15.4- inch diameter), a limited-slip differential and a leather and Alcantara-wrapped AMG sport steering wheel.
