CARS.COM — With the introduction of the 500-plus-horsepower 2018 Mercedes-AMG GLC63 S at the 2017 New York International Auto Show, Mercedes is continuing its path to hot-rodding everything by taking massively powerful engines and putting them in places they don’t normally belong, like a wagon and now a compact SUV. The GLC-Class is the former GLK-Class SUV and has a similar place in Mercedes’ SUV lineup as the C-Class does in its sedan lineup.

Now that the formalities are out of the way, Mercedes previewed a white GLC63 and matte charcoal GLC63 S coupe Tuesday night before the auto show’s start. There was no mistaking the rowdy crackle of the twin-turbocharged 4.0-liter V-8 — it’s that raucous V-8 rumble you don’t get with anything fewer than eight cylinders — as it lit up offstage before being corralled in front of the audience. The 4.0-liter makes 469 horsepower in the GLC63 and 503 hp in the GLC63 S. Mercedes says the engine is closely related to the V-8 in its AMG GT sports coupe — good news, everyone.
