The Mercedes GLC rolled onto the scene for the 2016 model year as a replacement for the aging GLK-Class. It took a good year, but Mercedes-AMG finally brought the GLC43, which was followed by the model you see here – the GLC63. Carrying the same general silhouette, the GLC63 brings its own unique styling cues that include the AMG grille, a more aggressive fascia, upgraded wheels and brakes, and an overall sportier appearance. But, it’s about a lot more than looks with AMG models, and that’s why the GLC63 comes with a 4.0-liter Biturbo V-8 crammed under the hood that’s good for 476 horsepower. But, if you step up to the GLC63 S you can have as much as 510 horsepower – that’s some serious power for a midsized SUV. This is the same engine that’s used in the AMG GT series and is backed by the 4MATIC+ AWD system, a limited-slip differential in the rear, air spring suspension, and adjustable dampers to help keep things from getting squirrely under the gun.
