The new Mercedes-Benz C63 AMG – or Mercedes-AMG C63 as it is now known – has been unveiled for the first time in both saloon and estate form.

Both are powered by a new 4.0-litre biturbo V8 that produces 476 hp at 5,500–6,250 rpm and 650 Nm of torque from 1,750–4,500 rpm.  In C63 S form, it develops 510 hp and 700 Nm of torque.

That kind of power is enough to propel the C63 S from 0-62mph in 4.0 seconds dead, with an electronically-limited top speed of 155mph.

It’s not all about power, however, with the company stating that the new C63 is up to a third more efficient than the outgoing model, recording CO2 emissions of 192 g/km.

Power is directed to the rear wheels by a revised version of the AMG Speedshift 7-speed transmission with quicker shift times, where it meets the tarmac through 245/40 R18 front and 265/40 R18 rear tyres.  The S model gains larger 245/35 R19 front and 265/35 R19 tyres.

Both models feature a new braking system with 390mm front discs and 360mm rear, with the option of ceramic discs.

Mercedes is keen to point out that weight has been firmly kept in check, with the saloon weighing in at 1,715kg and the estate at 1,785kg including fuel and driver.

The C63 uses a unique suspension set-up with a four-link system at the front, using independent steering knuckles and a wider track for increased stability, while the rear uses a multi-link system with increased negative camber.  Both make use of AMG’s Ride Control system with three-stage dampers, a mechanical locking rear differential for the C63 and an electronic version for the C63 S.

For the exterior, Mercedes gave the C63 new front bumpers with wide air intakes for the intercoolers, plus a new bonnet with subtle power bulges.  The front wings are wider, side sill extensions have been added, and the rear bumper has been redesigned to house the quad-pipe exhaust system.  The saloon gains a small lip spoiler on the boot lid, while the estate wears a subtle roof spoiler.

Inside, the C63 gains chunky sports seats, an AMG steering wheel and revised instruments, with options for AMG sport seats and a range of trim finishes.

The Mercedes-AMG C63 will be available to order next month, with prices and exact specifications to be announced shortly.  First deliveries are expected in spring 2015.
