Mercedes Debuts Hot 2018 GLC63, Coupe AMG Variants in NY

Say hello to the new, most powerful SUV in the premium mid-size segment; the Mercedes-AMG GLC 63 and GLC 63 Coupe. Although, if you want the most powerful engine on offer, you're stuck with the coupe-like rear end.

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.

The GLC - which shares running gear with the Mercedes C-Class executive saloon - competes for sales with the Audi Q5, and neither that auto nor the BMW X3 offers a version as powerful as the AMG GLC 63. For the regular GLC63 and the Coupe, it will display 469 horsepower (350 kilowatts) and 479 pound-feet (649 Newton-meters) of torque and for the flagship GLC63 S Coupe it will churn out no less than 503 hp (375 kW) and 516 lb-ft (700 Newton-meters). 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. The vehicle, which during testing was benchmarked against a Lotus Evora 400, Mercedes-AMG A45 and a Porsche Cayman GT4, will only be available as a coupe, and this time around there's no manual transmission.


Power is directed through a four-wheel drive system with a mechanical limited-slip differential for the rear, or an electronic limited-slip differential for the S version. That would make the GLC63 S Coupe the current quickest in its class if it lives up to the manufacturer's claims. Both come with Mercedes' latest version of adaptive air and damper suspension.

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. These work in tandem with a new three-stage stability control system, offering On, Sport, and Off modes, all catering for various driving styles.

Announced ahead of its world debut at the New York Auto Show, the 2018 Mercedes-AMG GLC63 triplets literally have the heart of a sports vehicle, using the same turbocharged eight-cylinder engine offered in the AMG GT lineup to make more than 500 horsepower and zoom to 60 miles per hour in less than 4 seconds. Also, as with the C63 coupe and cabriolet, the GLC63 coupes (and SUV) get wide-body fenders, broad front aprons, and rear diffuser elements between their rectilinear quad exhaust tips.


Along with the Panamericana grille, the exterior of both models are further differentiated by more aggressive styling featuring a wide front bumper that Mercedes-AMG says is inspired by the design of a jet wing. S models have contrast topstitching as well as an AMG Performance steering wheel covered in black Nappa leather.

With leather front seats and a leather-wrapped instrument panel with aluminum trim, the interior is just as sporty as the outside.
