Following the introduction of the S-Class Coupe last month, Mercedes-Benz has unveiled the more potent S 63 AMG Coupe version.

Like most recent AMG models, the S63 AMG Coupe adopts a rather tamed and restrained exterior appearance with a slightly more aggressive body equipped with larger vents, muscular side skirts and a quad exhaust with chromed tailpipes flanking the glossy black diffuser. It rides on 19-inch titanium grey multi-spoke AMG forged light alloy wheels wrapped around in 255/45 R19 and 285/40 R19 tires.

Its heart and soul is a twin-turbo V8 5.5-liter engine delivering 577 bhp (430 kW) and 900 Nm (664 lb-ft) of torque which makes it 41 bhp (30 kW) and 100 Nm (74 lb-ft) more powerful than the outgoing CL 63 AMG. Besides the added muscles, the S63 AMG Coupe is also 65 kg (143 lbs) lighter compared to its predecessor and offers a power-to-weight ratio of 3.41 kg / bhp.

The rear-wheel drive model needs 4.3 seconds to get from 0 to 62 mph (100 km/h) and has an electronically-limited top speed of 155 mph (250 km/h). Opt for the 4MATIC variant and the sprint time decreases to 3.9 seconds but we should mention Mercedes-Benz plans on offering this version only with a left-hand drive configuration. As usual, the engine is coupled to a seven-speed sports gearbox with three modes: "C" (Controlled Efficiency), "S" (Sport) and "M" (Manual).

Besides the usual AIRMATIC air suspension and MAGIC BODY CONTROL, the Mercedes-Benz S63 AMG Coupe can also feature a curve tilting function which debuted on the regular S-Class Coupe enabling the vehicle to "lean into bends in a manner similar to a motorcyclist or skier." It can be turned on between 19 mph (30 km/h) and 119 mph (180 km/h) and it's capable of diminishing the lateral accelerations felt by the passengers by inclining the body up to 2.5 degrees.

For more money the S63 AMG Coupe can 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.

Like most recent AMG models, there will be an "Edition 1" version available only one year after the car's launch. It will come with Swarovski crystals in the LED headlights, AMG sport seats wrapped in 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 2014 Mercedes-Benz S63 AMG Coupe will make its public debut next month at the New York Auto Show. Order books for the 4MATIC version will open in April, followed by the RWD model in July. Deliveries are slated to commence in September.
