Fuel Economy and Range

Regenerative brakes improve the M2 Competition’s fuel efficiency by converting inertia back into energy instead of wasting it. The C-Class Coupe doesn’t offer a regenerative braking system.


The M2 Competition offers a manual transmission for better acceleration, control and fuel economy. The C-Class Coupe doesn’t offer a manual transmission.

The M2 Competition offers an optional sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The C-Class Coupe doesn’t offer an SMG.

The M2 Competition Automatic’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The C-Class Coupe doesn’t offer launch control.

The M2 Competition’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the C-Class Coupe’s standard 45 series front and 40 series rear tires. The M2 Competition’s tires are lower profile than the C-Class Coupe’s optional 40 series front tires.
