2012 Mercedes-Benz C63 AMG Coupe unveiled

Just months after the world premiere of the 2012 C-Class coupe at the Geneva Auto Show, Mercedes-Benz has unveiled the car which they hope will lay waste to competitors such as the Audi RS5, and current benchmark of two-door sports cars, the BMW M3.

The C63 AMG coupe will be powered by the same 6.3-liter naturally aspirated V8 engine in the C63 AMG sedan. The hand assembled power plant produces 451 hp and 443 lb-ft. This allows the C63 AMG coupe to accelerate from 0-60 in 4.4 seconds. Although the C63 AMG coupe produces more horsepower than either the M3 or RS5, the real difference is with the amount of torque. The 443 lb-ft in the C63 AMG coupe is significantly more than the M3 or Rs5, with 295 and 317 lb-ft respectively.

The C63 AMG coupe can become even more potent with the addition of the optional Mercedes-Benz Performance Package. The package utilizes technology from the SLS AMG including forged pistons, connecting rods and lightweight crankshaft. This reduces the weight by 6.6 pounds. The addition of this high-tech equipment results in a total horsepower output of 481 hp and reduces the 0-60 time to 4.3 seconds. Other benefits include an increase in top speed from 155 to 174 mph (electronically limited). In addition to the performance modifications, the Performance Package features a number of cosmetic changes to the exterior of the vehicle. This includes the variable intake manifold finished in titanium gray, the AMG high-performance braking system with two-piece front rotors and red painted brake calipers, a carbon fiber spoiler and the AMG performance steering wheel.

Ironically, for a car having so much power and torque the C63 AMG coupe also has a greener side. The high-revving V8 is mated with the AMG SPEEDSHIFT MCT 7-speed sports transmission. The transmission allows the driver to select from a variety of driving modes, including the Controlled Efficiency or “C” mode. This limits the amount of acceleration and makes the transmission shift early, resulting in improved fuel economy.

However, most customers who are in the market for a world-class high-performance coupe are not concerned about the amount of gasoline being consumed, and do not want to be driving around with slow, conservative transmission settings. Luckily the transmission in the C63 AMG coupe has faster and more aggressive settings. The “S”, “S+” and “M” modes are available at the touch of a button, with the gear changes in the “S+” and “M” modes taking only 100 milliseconds. The C63 AMG coupe also has a Race Start function to provide the best possible launch.

If the lighter and more nimble C63 AMG coupe is anything like it’s four-door sibling then BMW and Audi will be forced to take notice. Mercedes AMG seems to have its eyes on taking the top spot in the two-door sports car category and continues to develop and produce vehicles which are getting closer to doing just that. The C63 AMG coupe is scheduled to make its first appearance in U.S. showrooms starting in September.
