The high-performance Mercedes-Benz C63 AMG sedan is now more attractive than ever thanks to restyling for the 2012MY. The C63 AMG sedan is complemented by numerous enhancements help maximize performance while significantly reducing fuel consumption. The sedan now features the award-winning AMG SPEEDSHIFT MCT 7-speed sports transmission with standard "Controlled Efficiency" mode along with a new power steering pump that helps reduce the combined fuel consumption by about ten percent (estimated figured for U.S. models pending). The output of the AMG 6.3-liter V8 engine is unchanged at 451 hp and can be increased to a maximum of 481 hp with the optional AMG Development Package. Agility, grip and ride comfort have been enhanced as a result of numerous measures to optimize the AMG sports suspension. New assistance systems and a new generation of telematics increase both safety and comfort. The U.S. market launch for the 2012 C63 AMG Sedan begins in autumn.
The 2012 C63 AMG sedan features a new radiator grille with a large Mercedes star and a single transverse louvre, as well as a new AMG front apron with a lower cross member painted in high-gloss black. Additionally highlights include special AMG daytime running lights and side air outlets which recall those found on the SL63 AMG high-performance roadster. New clear-lens headlamps emphasize the car's distinctive, confident presence especially when equipped with the optional Lighting Package featuring bi-xenon headlamps. The wide front fenders with the "6.3 AMG" badge and the new 5 twin-spoke AMG light-alloy wheels -- , finished in titanium grey. Good contact with the road is provided by the wide 235/40 R 18 and 255/35 R 18 tires at the front and rear.
The rear of the C63 AMG now features a new AMG rear apron featuring a distinctive, black diffuser insert with three pronounced fins.
AMG SPEEDSHIFT MCT 7-speed sports transmission from the SL63 AMG
Under the skin, the top C-Class model boasts a wealth of new technology including the AMG SPEEDSHIFT MCT 7-speed sports transmission - another advanced feature adopted from the SL63 AMG. This innovative transmission uses a wet start-up clutch in place of a traditional torque converter to deliver a much more efficient, agile and direct response. Fuel consumption and emissions have been reduced thanks to the "Controlled Efficiency" mode and a new power steering pump.
The AMG SPEEDSHIFT MCT 7-speed sports transmission impresses with its exceptional flexibility: with four driving modes as well as rev-matching and RACE START functions, it delivers comfortable shifts around town as well as instant response in high performance driving situations. The Controlled Efficiency "C" mode is programmed to provide smooth, comfortable upshifts while maintaining the lowest possible engine speed to help maximize fuel efficiency. The "S", "S+" and "M" modes deliver increased agility through fast, responsive gear changes and higher revs. Gear changes in the "S+" and "M" modes take just 0.1 seconds.
The naturally aspirated eight-cylinder engine with its large displacement of 6,208 cc develops 451 hp at 6,500 rpm and attains a peak torque of 443 lb-ft. at 5,000 rpm. The 2012 C63 AMG retains its predecessor's position as the top performing model in its segment with 0 to 60 acceleration in just 4.4 seconds while the top speed is 155 mph (electronically regulated).
AMG Development Package: technology transfer from the SLS AMG
Even more dramatic performance is available with the optional AMG Development Package offering 481 hp and a 0-60 mph acceleration time of 4.3 seconds. The Mercedes- AMG engine experts have achieved this increase in output thanks to a technology transfer from the SLS AMG with forged pistons, connecting rods and the lightweight crankshaft all coming from the gullwing model's engine. The reduced mass inertia of the components - which are 6.6 pounds lighter than those of the standard version - allows the naturally aspirated eight-cylinder engine to rev up with even greater ease and agility. Models equipped with the Development Package can be identified by the variable intake manifold painted in titanium grey under the hood, the AMG high-performance braking system with two-piece front discs and red painted brake calipers at all four corners, a carbon-fiber spoiler lip on the trunk lid and the AMG performance steering wheel in premium leather with a unique grip area.
