While the standard CL500/550 is packing around 388hp (285kW) from its 5.5L V8, WAM has upped this already impressive figure to a heady 450hp (335kW) - less than 70hp (52kW) off the 517hp (385kW) that the twin-turbo V12 manages to make in the standard CL600. Incidentally, torque has also been increased to a significant 770Nm (575lb-ft.), giving the WaM CL45 more than enough power to give its prospective owners a scare.
The power bump comes from a custom exhaust system that features sport catalysts and an upgraded manifold, updated ECU and a valve-controlled rear muffler. The car is then lowered to give it that aggressive stance, and WAM also claims that an upgraded suspension system helps the car cope with that extra power around corners.
Finally, finishing off the package are those TS-1 ultralight forged wheels - probably our least favorite part of the car. We're just thankful that the company is called WheelsAndMore, and not just Wheels, otherwise we mightn't have had so much to write about.
