Matching super luxury with supercar character, the 2012 Mercedes-Benz CLS63 AMG made its world debut at the LA Auto Show. On sale next summer, this ultra-sleek sedan builds on the riveting visual presence of the all-new 2012 CLS-Class with a full measure of added style and scintillating performance served up in true AMG fashion -- including its all-new biturbo V8 that boasts even more power with up to 33 percent better fuel economy.
Making extensive use of lightweight aluminum body panels -- including its doors, uniquely contoured hood and wider fenders -- the 2012 Mercedes-Benz CLS63 AMG asserts its aggressive character with a bold front fascia treatment that teams a grille treatment similar to the SLS AMG gullwing coupe with a deeper lower skirt. Out back, the CLS63 AMG gets a unique rear diffuser insert and tasteful decklid spoiler lip set off by dual-paired chrome-tipped exhaust finishers. To ensure that its driver can see as well as be seen, the new CLS63 AMG will be available with the world's first corner-following "active" LED headlamps that consist of 71 individual LED elements and also incorporate M-B's Adaptive Highbeam Assist function.
Inside, the CLS63 AMG receives a similar load of tasteful enthusiast-grade enhancements to its lavishly appointed cabin, starting with super-supportive AMG sport seats in premium hand-fitted leather, a unique AMG performance steering wheel with aluminum paddle shift levers and the choice of burl walnut trim or optional piano-black lacquer or carbon fiber accents.
Heart of the 2012 CLS63 AMG is a new 5.5-liter twin-turbocharged V8 incorporates direct injection and variable camshaft timing and air-to-water intercooling with efficiency enhancing start/stop technology. This all-alloy stunner makes 518 horsepower and 516 lb-ft of torque -- 11 and 51 units of output, respectively, above the 6.3-liter V8 used previously. Backed by the stunningly quick AMG Speedshift MCT7 seven-speed/multi-mode sport transmission, it can send this primo Mercedes streaking from 0-60 mph in 4.4 seconds and take it to 155 mph while still managing to return 16 mpg in the city and 21 mpg on the highway. That's nearly one-third better overall economy than its predecessor and best among its key rivals. Mercedes also will offer the car with an AMG Performance Package that bumps the maximum turbo boost from 14.5 to 18.8 psi, a change that nets 550 horses, 590 units of twist, trims a tenth of a second from the 0-60 mph sprint interval and raises its top end to 186 mph.
As in any AMG variant, the transition includes a comprehensive chassis revamp to make the best use of its added power. Here, it brings a purpose-tuned AMG Adaptive Suspension package with driver-selectable Comfort/Sport/Sport plus settings, a special three-stage ESP stability system, AMG-spec electro-hydraulic power steering and wider track dimensions. To optimize grip, the 2012 Mercedes-Benz CLS63 AMG wears sticky 255/35 front/285/30 rear performance tires on 19-inch AMG alloy wheels while massive anti-lock brakes with vented/cross-drilled rotors deliver serious stopping power. Joining the comprehensive suite of safety features in the new CLS63 AMG are two new optional driver aids: Active Blind Spot Assist and Active Lane Keeping Assist, which for the first time gets linked with the existing ESP package. Both in included in the Driver Assistance Package.
Although no formal pricing announcement was made at the LA Auto Show, Mercedes did reveal that it's preparing a distinctive 2012 CLS63 AMG Launch Edition that pairs special matte-finish Manganit Gray Magno paint with metallic-look "Corteccia Pearl" designo leather interior trim which will be accented by anthracite Alcantara, carbon-fiber and piano-black lacquer accent and other AMG trim elements.
