The ludicrously fast Mercedes-AMG GLC63 has been given a mid-life makeover, including a load of new driving modes to sharpen up its on-track handling.
Mercedes calls the system AMG Dynamics. There’s a choice of modes ranging through Slippery, Comfort, Sport, Sport+, Individual and, in the GLC63 S, Race. Each mode varies the level of assistance from the traction and stability control so that the GLC63 is just at home pootling around town as hammering round a race track. We’re not sure how many owners of high-riding SUVs – even ones as fast as this – actually go on track days. But the GLC63’s record-breaking lap time around the Nurburgring Nordschleife (7 minutes 49.369 seconds) is a pretty good indication that it won’t topple over if you need to swap lanes on the motorway in a hurry.
Elsewhere, the facelifted GLC63 get new headlights, tail lamps and a 90mm tailpipe outside, and a new steering and a voice- and gesture-controlled MBUX infotainment system inside. A 12.3-inch TFT sits in front of the driver, with a 10.25-inch screen in the middle of the dashboard. There are various new wheel, paint and upholstery options, as well. Underneath, as well as the AMG Dynamics system, there’s now a standard locking differential. Curiously, it also comes with Trailer Manoeuvring Assist – does Mercedes think caravanners buy this sort of car?
All the changes apply to both the regular GLC estate and the GLC coupe.
Under the bonnet you’ll find AMG’s prolific 4.0-litre, twin-turbo V8 engine producing 476hp and 479lb/ft in the GLC63, and 510hp and 516lb/ft in the GLC63 S. Either way, the engine send the power through a nine-speed, dual-clutch MCT-9 gearbox to 4Matic+ four-wheel-drive.
The GLC63 is good for 0-62mph in four seconds flat and a limited top speed of 155mph. The GLC63 S is 0.2 seconds quicker to 62mph and runs on to 175mph. Again, those numbers apply to both estate and coupe.
Fuel economy, if it matters, is in the low-20’s, with Co2 emissions of around 280g/km.
Mercedes hasn’t mentioned prices. But, as a guide, the current GLC63 costs around £70,000 and the GLC63 S weighs in at £76,000.
