GSC Stealth Mercedes-Benz CLS63 AMG [w/ Video]

GSC Mercedes-Benz CLS63 AMG Stealth front 3/4 view

The Mercedes-Benz CLS63 AMG is a four-door tour de force right off the showroom floor. The 5.5L twin-turbo V8 kicks out 518hp and 516 lb.-ft of torque (or 550hp and 590 lb.-ft if you order the AMG Performance Package) and blasts it to 60 mph in a claimed 4.4 seconds. And thanks to the combination of the low, coupe-like roofline and the AMG styling bits, this musclebound Mercedes looks as fast as it is. What’s not to like about that?

Well, one possible qualm would be that there isn’t much AMG will do to differentiate one CLS63 AMG from another, other than colors and wheel styles, of course. So what’s the individualist buyer to do? Talk to the aftermarket, of course! And the latest tuner to give the new hot CLS its special touch is German Special Customs, or GSC for short.

If you look past the matte gray (with smatterings of black on the wheels, decklid, grille and other trim bits) that gives it its name (Stealth), you’ll notice the much deeper front bumper with big, gaping openings, bulging front fenders and rear fender flares, rocker panel extensions, rear bumper with integral diffuser, and a hood with rear-facing extractor scoop and SL-style cowl vents. You’ll also notice the Mercedes-Benz star badges have been replaced with emblems featuring GSC’s intricate coat-of-arms-esque logo.

So you’re probably thinking GSC has added some extra muscle under that new hood to back up those more muscular looks, right? Well, in a word, no. There’s no word of any drivetrain, suspension or brake upgrades being added to make the Stealth perform even slightly closer to its warbird namesakes. Then again, with up to 550hp and 0-60 sprints that take less than four-and-a-half ticks of the watch, you couldn’t really add much more mojo before you start overwhelming the tires anyway (at least in the lower gears of the 7-speed automatic transmission).

GSC is also keeping the prices for the parts required to turn a CLS63 AMG into a Stealth close to its Brust. We’re guessing the total price for the package and the donor car will be comfortably below $150,000 if you don’t go totally bat-scat with the options (starting MSRP for a new CLS63 AMG is $94,900). That’s a lot of dough, but you do end up with a car that’s less common and, if you ask us, better looking than a Porsche Panamera Turbo. Of course, the Hunchback of Zuffenhausen is a bit faster. Decisions, decisions…
