2020 Mercedes-AMG GLC 63 drive review: Scaring the neighbors

Just how much performance does the GLC 63 offer over the run-of-the-mill GLC-Class?
Short answer: a lot. The twin-turbocharged 4.0-liter V8 that’s been spreading through the AMG lineup churns out 469 hp and 479 lb-ft of torque, sent to all four wheels via a nine-speed automatic transmission. Mercedes’ 4Matic all-wheel-drive system is the only option with this model, even if it never snows in your area. The SUV version makes the sprint from 0-60 mph in 3.8 seconds — a tad slower than the GLC 63 S coupe mode. But the fact that it’s below 4.0 seconds is what counts because it’s very impressive for something with so much heft and so much metal and leather on board — these were supercar figures a decade ago, lest we forget — but the 503 hp and 516 lb-ft of torque of the S coupe only allow you to shave off 0.2 seconds off of that sprint time.
Aside from its 3.8-second-to-60 time, the GLC 63 has other charms. For one thing, it looks like a GLC-Class SUV and offers the versatility of the tall wagon body style, which is handy for hauling all the gear that one’s overscheduled scions need during the course of a single day. There is plenty of new tech inside, courtesy of the update the GLC-Class has received for 2020. This means the latest MBUX with voice commands, an AMG Sport suspension system based on Air Body Control and plenty of driving modes. The interior is different as well, with seats built to cope with the g forces of being late to piano practice, and an AMG Performance steering wheel for taking corners a little too close in an attempt to not be late to piano practice.
How will you communicate to the outside world (aside from the badge) that you’re driving a GLC 63 and not one of the run-of-the-mill GLC 300s? Well, for starters, there’s the AMG 20-inch wheels, as well as the AMG Performance Exhaust System. On the inside, the GLC 63 AMG model also offers AMG logos on most, if not all surfaces, including the doorsills, so that your guests (who own something else) know that they’re not entering just another GLC 300 4Matic. If the illuminated doorsills don’t get the AMG-ness of this model across when your in-laws are in town and you have to pick them up in the airport, the 64 colors of the ambient lighting will give them a little hint that this particular GLC is something special.
