Following the introduction of its sedan counterpart last year, Mercedes-Benz has unveiled the fastest and most exclusive version of its new flagship – the S 63 AMG Coupe ahead of its official debut at the New York Auto Show next month.

AMG lightweight performance

Under the hood of the new S63 AMG Coupe is a twin-turbo V8 5.5-litre engine delivering 430 kW and 900 Nm of torque to all four wheels which makes it 30 kW and 100 Nm more powerful than the outgoing CL 63 AMG.

The two-door coupe accelerates from 0-100 km/h in 4.3 seconds and reaches an electronically-limited top speed of 250 km/h. All this power is managed by the company’s seven-speed AMG Speedshift automatic transmission with three modes: “C” (Controlled Efficiency), “S” (Sport) and “M” (Manual).

The power also runs to the ground through an AMG-tuned 4Matic all-wheel-drive system, with a standard 33/67-percent split torque. Stop/start is also standard. The 4MATIC variant can sprint from 0-100 km/h in 3.9 seconds.

Curve titling function – a world first

There is also a world first for series-produced cars in the shape of the curve tilting function. This function allows the S 63 AMG Coupe to lean into bends in a manner similar to a motorcyclist or skier.

The lateral acceleration acting upon occupants is reduced in a way akin to when driving in a steep curve, and passengers sit more firmly. The curve tilting function can be selected as one of three drive modes using the ABC switch; it is active in the speed range from 30 to 180 km/h.

Additionally, the S63 Coupe features the full air-suspension system AIRMATIC with the adaptive damping system ADS PLUS. Specific front axle kinematics – including higher camber, a larger anti-roll bar and a stiffer subframe carrier on the rear axle – have been developed exclusively for the S63 AMG 4MATIC Coupe.

Sporty looks and design features

The Coupe can further be configured with ceramic composite brakes as well as 20-inch ten-spoke AMG Performance Studio wheels, while on the inside there are AMG sport seats, Nappa leather upholstery and a flat-bottomed three-spoke steering wheel.

Another feature displaying the hallmark AMG look is the high-resolution TFT colour AMG instrument cluster with two animated round dials, as well as the new, innovative touchpad, included as standard equipment, which makes it easier to operate the radio, telephone and navigation system.

The safety and assistance systems are the same as those for the S550 4MATIC Coupe.

The Edition 1 variant

There will also be an “Edition 1” version available which will come with Swarovski crystals in the LED headlights, AMG sport seats upholstered in designo Exclusive Nappa leather, bespoke floor mats, illuminated AMG lettering on the door sill panels, Night View Assist Plus, a high-gloss black wood trim and other goodies.

The 2015 S63 AMG Coupe will celebrate its world premiere at the New York International Auto Show in April 2014.
