As we've seen just a couple of weeks ago with the regular Mercedes-Benz GLC models, it would only be a matter of time before the facelift treatment was extended to the range-topping AMG 63 and 63S variants. Yes, these are the biturbo V8 models with 476 hp and 510 hp respectively, as well as 650 Nm of torque and 700 Nm of torque respectively as well. The mechanicals in that sense are unchanged, as power is still sent to all four wheels via the 4MATIC+ system and the AMG Speedshift MCT 9G automatic transmission.
So what has changed? As usual, we'll highlight the fact that the ageing entertainment system has finally been upgraded to MBUX, but in a more sedate version without the huge dual screen display that quite nearly defines the system with its introduction in the A Class. MBUX offers better connectivity as well as easier operation, and in the last year or so has become the industry standard by which we measure other entertainment systems.
There's a new headlamp and tail lamp design, which loosely mirrors that of the regular GLC models. New massive 21-inch alloy wheels are also available as an option, over the already massive 20-inch alloy wheels it comes with from factory. The exhaust tips are a little darker though not all-too-different from the model it replaces, which helps to make the GLC 63 a little stealthier. There's also a new graphite grey metallic paint option - although this isn't particularly exciting as Mercedes-AMG has always had a huge range of colour options.
On the inside, it's the usual changes with a better AMG steering wheel and more buttons to push - an item that's seemingly optional on the non 'S' models - as well as magma grey and black upholstery with contrast yellow stitching. On the whole it's these minor touches that help the GLC63 and GLC63S models to stay relevant, regardless of whether you opt for the SUV or Coupe body styles.
The AMG Dynamic Select drive program gets a couple of updates, with dynamic handling control options in addition to the regular mode settings which adjust the steering, throttle response, and suspension stiffness. There's a new "Slippery" mode, which is for - you guessed it - slippery conditions. There are also electronically controlled locking differentials as standard across all the models, which should help with putting power down predictably.
And that's all there really is to it. It's a model we absolutely love, and Mercedes-AMG has wisely avoided deviating a great deal from a winning formula. The GLC platform is one that follows the traditional SUV form to a T, and shoving one of the most powerful Mercedes-AMG powertrains in there instantly provides it with a Jekyll-and-Hyde dichotomy.
