Mercedes is aiming to outgun BMW’s M3 coupé and the Audi RS5 with this hardcore AMG version of its recently launched two-door C-class.
The C63 AMG coupé produces up to 480bhp from its normally aspirated V8 motor, putting it well clear of its two German rivals and giving the model raw acceleration that wouldn’t disgrace a mid-engined supercar.
Unlike the recent CLS AMG, the C-class coupé from Mercedes’ in-house tuning division sticks with the familiar 6.2-litre, normally aspirated V8 engine. In the latest spec, the unit produces 451bhp and 443lb ft, more power and considerably more torque than the BMW (295lb ft) or the Audi (317lb ft). That’s enough to take the C-class from 0-62mph in 4.5sec, with a limited top speed of 155mph.
However, Mercedes will also offer an AMG Performance Package for the car, swapping the front brakes for composite items, adding interior flourishes and adopting the pistons, connecting rods and crankshaft from the version of the engine used in the gullwing SLS AMG supercar. The tweaks increase power to 480bhp (torque stays the same), cutting a further 0.1sec from the 0-62mph time.
Just one transmission is available: AMG’s seven-speed Speedshift automatic. It offers a number of modes, accessed via a rotary controller (another SLS AMG carryover), that cut shift times to as little as 100ms. There’s also launch control.
The C63 AMG coupé gets a different chassis set-up from the regular two-doors, with three-link front suspension, multi-link rear suspension and wider track at both ends. There’s also more negative camber, thicker anti-roll bars and revised spring and damper rates.
