Will eventually go up against the BMW X3 M.
It was less than two weeks ago when our spies caught on camera a partially camouflaged prototype of the Mercedes-AMG GLC 63 Coupe and now the crossover has been spotted in its regular body style. Compared to our first batch of spy shots from May with the GLC 63, the latest images are a tad more interesting because the prototype appears to be wearing most of the production bits.
Not only does it have the final exhaust system with the ‘63’-specific tips, but there’s also something going with the roof-mounted rear spoiler. It appears to have an add-on component the older prototype lacked, which is a sign the range-topping GLC will be more than a V8-engined version as it will also host an assortment of aerodynamic tweaks. It remains to be seen whether it’s going to get an integrated active rear spoiler like the 2018 Porsche Cayenne or it will be a fixed part sitting above the spoiler, although we doubt that.
Since we’ve mentioned the V8, it’s obviously Mercedes-AMG’s familiar biturbo 4.0-liter available in a multitude of power stages. The strongest iteration of the eight-cylinder generates a monstrous 603 horsepower (450 kilowatts) and 627 pound-feet (850 Newton-meters) of torque in the E63 S, but it’s highly unlikely the GLC 63 will match or even get close to that. A more realistic expectation would be 503 bhp (375 kW) and 516 lb-ft (698 Nm) as in the C63 S, or slightly more than that.
Regardless of how much power it will get, the first-ever GLC 63 will come as standard with an all-paw 4Matic setup. It will be interesting to see whether the power transfer will be done via the usual seven-speed automatic or the 9G-Tronic implemented in the aforementioned E63.
As far as outright performance is concerned, the GLC 63 should cover the 0-62 mph (0-100 kph) in about 4.0-4.1 seconds taking into account the warm GLC 43 needs 4.9 seconds to complete the task. As usual, top speed will be electronically capped at 155 mph (250 kph), but there might be an optional AMG Driver’s Package featuring a less restrictive limiter.
Sitting above the V6-powered GLC 43, the 63-badged model will be introduced sometime next year and it is going to be followed shortly by the equivalent GLC 63 Coupe.
