As per the C63 sedan and wagon, the coupe features a twin-turbo 4.0 litre V8 capable of either 350kW and 650Nm or a high output C63 S that musters 375kW and 700Nm.
Australian buyers will only be offered the high output C63 S, which also picks up an electronically actuated limited-slip differential, linked to the car’s ESP system. Standard C63 coupe’s come with a mechanical limited-slip diff instead.
Delivering that power to the rear axle is the same AMG Speedshift MCT (multi-clutch transmission) seven-speed auto, with a wet startup clutch in place of the usual 7G-tronic auto’s tourque converter. Gear shifts are faster than before, manual gear changes can be made via the steering-wheel paddles.
Four different driver-selectable transmission modes are avaialble, with C63 S models including a sharpened ‘Race’ setting.
The C63’s aggressive style comes courtesy of a set of unique front and rear bumpers, plus wider front and rear guards, giving the Mercedes-AMG a wider, more planted stance.
Already benefitting from the sleeker roofline, and longer bonnet of the C-Class coupe range, the only carry-over panels between the C63 coupe and the regular range are the roof, doors and boot lid.
Beneath the wider bodywork, the C63 S will sit on 19 x 9.0 inch front wheels shod with 255/35 R19 tyres, and huge 19 x 10.5 inch rear wheels wearing 285/30 R19 rubber.
Both front and rear track have also been widened, with the C63 coupe running an AMG-specific four-link front suspension and multi-link rear end.
The C63’s soundtrack is provided by a specially tuned exhaust, with an automatically controlled flap that matches engine noise to driving parameters. An optional performance exhaust is also available which allows exhaust noise to be controlled at the push of a button.
On the inside, the C63 coupe comes with a unique AMG instrument cluster, and sports seats trimmed in Artico and Dinamica man made leather. Optional performance seats are also available, which position occupants lower, and feature more contoured support.
The Mercedes-AMG with make its debut at the Frankfurt Motor Show. Australian deliveries are expected to begin around the middle of 2016.
