Interesting comparison here of the Mercedes-Benz C63 AMG against the BMW M3.
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.
