AMG Mercedes

Just three years ago, Mercedes Benz CLS had amazed the market by its fashion runway of the world's first four-door coupe. And now, Mercedes has officially unveiled the changes to the 2009 CLS four-door coupe. Without a doubt, the CLS coupe had created an automotive industry trend toward more attention-grabbing, eye-catching four-door cars - vehicles that blur the line between sedan and coupe.

Lately, there has been so much talk in the internet chatrooms about whether the new AMG 6.2-liter naturally aspired V-8 engine is an innovation over the supercharged 5.4-liter that was an AMG staple - particularly, if the new model is slower or quicker off the mark. At least for now, the new CLS63 AMG, we can say that the answer is both yes and no. The 6.2-liter V-8 releases 507 horsepower in the CLS which is easily surpasses the 469 hp in the old CLS55 AMG. On the other hand, torque has decreased from 516 pound-feet to 465 lb-ft. Actually, more torque means faster mid-range and off-the-line acceleration, while more power results in better top-end performance.

Similar to what's mentioned above, the Mercedes Benz CLS63 AMG is powered by V-8, which is the most powerful naturally aspirated production as well as the first engine developed completely by AMG. This powerful feature is built almost completely from a high-strength silicon-aluminum alloy which makes AMG racing success spur high-power production.

One of the cosmetic changes is the sleek new nose of the CLS complemented by a more dramatic two-bar grill. Originally, the CLS had a four-bar grill and to add a little flavor, they have crafted it with a two-bar grill. What else is fairly noticeable is the new CLS features a built-in arrow-shaped turn signal on its large outside mirror. In addition, the new dual five-spoke 18-inch wheels make the car appear even more striking. A new rear bumper with trapezoidal dual exhaust pipes and arrow-shaped LED tailings gives the car a unique and fresh new look.

Amazingly, the CLS63 romps to 60 miles per hour from its initial point in a blistering 4.1 seconds which is a tenth quicker than the CLS55. And to make sure that it will stop as fast as it goes, it comes equipped with new, giant vented and perforated disc brakes with all around feature such as 14-inch discs and six piston calipers up front and 13-inch discs with four piston calipers at the rear attached. The AMG suspension is a recalibrated version of Mercedes' Airmatic air-spring setup, which works in conjunction with the so-called Adaptive Damping System. It has driver selectable settings just like the system in the E-class, none of which are perfect.

So what are the other benefits of the new engine of the CLS63? Besides the fact that it teases the 7200-rpm redline, it really does go past 180 miles per hour. Also, not to say that the old five-speeder was not good, its seven-speed automatic transmission is as smooth as a glass of fine aged wine from the cellar. The seven-speed AMG Speedshift automatic transmission can be shifted manually by either a conventional lever or by the Formula-1 style shift paddles on the back of the steering wheel - right for upshifts, left for down.

Other features included 19-inch alloy wheels, larger front discs, limited slip differential as well a leather and Alcantara-wrapped AMG sport steering wheel.
