During this lull in Mercedes’ CLA charm offensive, we thought we’d bring you word of a new model from the German marque at the other end of the scale:

The C63 AMG “Edition 507.”

For this performance-enhanced version of one of MB’s already musclebound sedans, the output of the AMG 6.3-liter V8 engine has been increased by 56 hp, bringing the output to 507 hp with 450 lb.-ft. of torque.

2014 C63 AMG "Edition 507"

Thanks to that and some tech borrowed from the SLS AMG supercar, the 2014 C63 AMG “Edition 507″ can do 0 to 60 mph in 4.1 seconds and hit a top speed of 174 mph.

Mercedes will releases pricing info closer to this summer’s launch, so no need to smash the piggy bank quite yet…
