Mercedes-Benz reveals new details on their C63 AMG model. The new coupe is based on the recently introduced C-class and it is currently the smallest AMG model offered by the Stuttgart-based automaker. In the sporty premium coupe segment, the C63 AMG goes against BMW’s E92 M3 Coupe.

The 6.2 liter V8 naturally aspirated engine found in the C63 AMG produces in “standard” form 457 horsepower, but with the addition of the optional AMG Development Package, the power output is raised to 487 horsepower. The package includes forged pistons and connecting rods, and a lightweight crankshaft like the SLS sports car, red brake calipers and a carbon spoiler lip on the rear lid.

The special parts save 6.6 pounds, make the engine more responsive and allow it to rev higher than the standard version. The extra power helps the C63 AMG run to 100 km/h in just 4.3 seconds, a tenth of a second faster than the non-tuned engine. Top speed is also boosted to 174 mph from 155 mph for the standard AMG version. In both cases the car’s top speed is electronically limited. The new C63 AMG is also said to run about 15% more efficient than previous generation, 12.0 liters per 100 km.

BMW’s M3 Coupe is powered by one of the last naturally aspirated engines available at the Munich-based automaker. The 4.0 liter engine produces 420 horsepower and aided by the 7-speed DCT, rungs to 100 km/h in 4.6 seconds.Fuel fuel consumption for the M3 with DKG is just below 11.2 liters per 100 km, while the manual transmission registers a slightly higher number, 12.4 l/100km.

U.S. pricing has yet to be announced for the new C63 AMG Coupe, but in Europe the base price starts at € 72 590, just marginally above the sedan and just below the Knaupp Estate. Adding the AMG Development Package adds € 7116.20 to the base price. In comparison, the BMW M3 Coupe starts at € 68 750 € and with another € 4300, the aggressive Competition Package can be included.

As always, we took the time to visually compare the two vehicles.
