The
C63's main car opponents are the M3 and the RS4 or RS5. Contrary to what the
M3's definition says of it, the C63 has a 6.2 liter V-8 that produces
457 hp compared to the M3's 420 hp and
443 lb-ft of torque compared to the M3's miserable
295 lb-ft of torque. Along with this, the way most M3 drivers get more power is through forced induction and the use of either a supercharger or a turbocharger.
The competition between Mercedes and BMW owners has going on for a long time. Neither of them realized that each car has its
strengths and weaknesses. The
M3 for example, is better on a track and in the corners then a C63. The C63 on the other hand, is much faster in
the straights and is getting better in the corners.
