The C63 saloon and two-door models both share a twin-turbocharged 4.0-litre V8 engine. The unit currently outputs 469bhp in its entry form, but a small increase may be offered with the facelift.
The current S model is good for 503bhp but other cars in the AMG range far exceed that, such as the 563bhp E63, illustrating the breadth of performance the unit can offer.
Minor changes are due for both models' exteriors, with refreshed bumper designs featuring different intakes and a new grille the clearest differences. There will also be adjustments to the car's day running lights - as shown by the camouflage.
