Mercedes-AMG unveils 469-horsepower GLC 63

While Mercedes would surely like to talk about the run-of-the-mill GLC Coupe, we're going to cut right to the good stuff and talk about the AMG models first.

As mentioned, the Mercedes-AMG GLC63 is powered by a twin-turbocharged 4.0-liter V8 which is capable of producing 469 horsepower and 479 pound-feet of torque. But there's nothing old-school about the way AMG has done it, first with the C-Class sedan and now in beetle-crusher format with the GLC 63.

A nine-speed automatic transmission comes as standard, and although so far Mercedes is keeping schtum on the exact performance figures each vehicle will easily hit its limited top speed of 155mph. All feature AMG's paddle-shifted nine-speed automatic and a performance-tweaked all-wheel-drive system that allows for full variability between rear- and all-wheel drive. All of this kit is good for acceleration from 0-60 miles per hour in 3.9 seconds in the standard GLC63 and GLC63 Coupe, and 3.7 seconds in the GLC63 S Coupe. The GLC63 models are scheduled to go on sale in the U.S.in early 2018. That would make the GLC63 S Coupe the current quickest in its class if it lives up to the manufacturer's claims.

The vehicles are also fitted with an ECO stop/start feature that is enabled in the Comfort mode, which also decouples the engine from the transmission when coasting between 37 and 99 miles per hour.

All GLC63 models are suspended on air springs with adaptive dampers, with standard GLC63 coupes riding on 19-inch wheels with 235/55 front and 255/50 rear tires. The GLC63 S Coupe, on the other hand, features an electronic rear limited-slip differential. These work in tandem with a new three-stage stability control system, offering On, Sport, and Off modes, all catering for various driving styles. There is also an exhaust system with flap technology for variable engine sound, with the flap controlled automatically depending on the AMG Dynamic Select drive program.

Mercedes-Benz has unveiled the most powerful and most extreme versions of the GLC premium SUV to date, the Mercedes-AMG GLC 63 and GLC 63 Coupe.

The new model is the last of the present range of Mercedes SUVs to be given the hot-rod treatment - there are already AMG versions of the GLS, GLE, and unmistakeable G-Class. Along with the new grille, you've got a more aggressive front bumper, wider wheel arch claddings, new side sills and a strong rear bumper with AMG's hallmark quad tailpipes. Upholstery choices include two-tone Red Pepper/Blackor Platinum White/Black Nappa leather. According to CNET, the AMG GLC63 also has a wet clutch that replaces the torque converter. Both the SUV and the Coupe variants can reach those figures while the upgraded GLC63 "S" Coupe version can reach 503 hp and 516 lb-ft of torque.
