Along with the introduction of a restyled CLS four-door coupe, Mercedes-Benz also updated its top performance CLS 63 AMG version, making it look fiercer and react even better to the driver’s inputs.
The most noticeable changes can be seen at the front of the car, where it got redesigned LED headlights with new eyebrow-shaped daytime running light strips, a twin-bade radiator grille as well as a gaping lower grille split by an A-styled winglet. The rear section comes with a black diffuser insert with pronounced fins, more vents and new exhaust tips, while the sides are adorned with new side skirts and 19-inch black wheels.

On the inside, the CLS 63 AMG boasts with a new steering wheel with paddle shifters and a lower metal insert as well as a new free-standing color display on top of the central console powered by an all-new multimedia infotainment software, Alcantara trimmings and different other color/material combinations.

Mechanically, the performance four-door coupe comes with an improved MCT 7-speed automatic transmission that is said to respond faster than its predecessor.

Shortly after Mercedes Benz presented their brand new CLS model at the 2010 Paris Auto Show, their performance arm AMG did the exact same thing in updating the CLS 63 AMG.
Following the tradition of AMG-spec cars, the new CLS 63 AMG contains only slight visual changes as compared to the CLS, among those being a more aggressive front fascia, side skirts and prominent quad exhaust outlets. Safety-wise, the new CLS 63 AMG comes packed with roadside assistance, adaptive dual stage front airbags, driver knee airbag, side and full-length curtain airbags and active head restraints.

Slightly different form the earlier version, the latest facelifted CLS 63 AMG brings little new to the line-up except some minor restyling and interior enhancements.
Powered by the AMG-built V8 unit, the new CLS delivers the same unearthly +500 hp power channeled to the wide rear wheels through a Mercedes signature automatic 7-speed G-Tronic transmission with manual mode. This almost-magical gearbox complements the smart-chassis through its choice of three driving settings (comfort, dynamic and sport). The torque converter provides max reliability and a smooth ride with no lag between gear shifts.

The CLS was the car that brought the “4-door coupe” name on the market when it was introduced in 2004.
Two years later, after a huge success on the market, it received the CLS 63 AMG version.

The CLS exceeded the brand’s expectations when it was introduced in 2004 and, in the following year, its sales went over 20.000 units. And it did that again in 2006. For the German car-maker it was clear that the buyers want something more. And that “more” was translated in more power and more opulence. The CLS 63 AMG was the right answer and it was introduced as a replacement for the CLS 55 AMG.

In the front, there was a new front bumper with an integrated spoiler that was inspired by the F1 race-car. The big central air-intake was accompanied on the sides by the other two air-dams for the big disc-brakes. On the front fenders, the manufactured installed a chromed “6.3 AMG” badge. A discrete lip on the trunk lid was added for an additional visual effect.

Inside, the CLS 63 AMG featured sport-bucket seats with high bolstering for the torso, but not too much for the base. The interior of the car featured wood grains and leather, despite the car’s performances. The instrument featured a TFT display in the middle of the speedometer.

The CLS 63 AMG was not as powerful as the most powerful 55 AMG engine. It offered 507 hp (the 2006 SL 55 AMG had 510 horses). The 6.3-liter engine was limited in its power and torque to be fitted with the newly developed AMG Speedshift Plus 7G-Tronic which could not handle the same amount of grunt as the older 5G-Tronic gearbox.

When Mercedes-Benz introduced the CLS at the 2004 New York International Auto Show, the world stood still.
It was the first new-age, four-door coupe on the market. This kind of bodywork was long-forgotten and only a big brand such as Mercedes-Benz could revive it and receive applause. In the autumn of same year, the carmaker introduced the CLS 55 AMG at the Paris Motor Show. It was the fast coupe with four doors.

The exterior look was drastically enhanced compared with such as CLS500 or the CLS320 CDI versions. Its big, 18” wheels (19” as an option) had a special design. The car was lowered by 10 mm (0.4”) than the rest of the CLS range The Airmatic suspension was standard and the entire setup was stiffer, for better handling. But some people still didn’t like the dropped back of the car.

Inside, the CLS 55 AMG featured a combination of sporty styling and high-quality materials. The new AMG sports seats shows special AMG perforations, double stitching and Alcantara panels. It also includes nappa leather in three colors variants.

The supercharged 5.4-liter V8 engine offers 476 hp and 700 Nm (516 lb-ft) of torque. It was mated to a 5-speed automatic gearbox. The result is a spectacular 4.7 seconds for a 0-100 kph (0-62 mph) sprint and a limited top speed of 250 kph (155 mph).
