You might as well change those two ’Ms’ with two ’Ns’ because the guys of Wimmer RST are unquestioned winners in our minds. As one of those tuning companies that take painstaking lengths in refining their past products, the German tuning firm went back to their prior program for the Mercedes C63 AMG and gave the Merc’s 6.3-liter V8 engine more pop under its hood.
From their past project, which gave the car 580 horsepower from the standard 457 horsepower, Wimmer went back to the shops and re-tuned the engine, which now boasts of an output of 601 horsepower and 532 lb/ft of torque. That number translates to a power-to-weight ratio of 2.79kg/horsepower and a new top speed of 204 mph, up from the electronically limited 189 mph figure of the previous incarnation.
The engine upgrade was made possible by the addition of of new modifications, including a sports camshaft, re-tinkered cylinder heads, a new optimized air intake, custom manifold catalytic converters, a sports air filter, and a new stainless steel exhaust system. Controlling the added power is a set of BBS CH-R alloy wheels (8.5 or 9.5 x 19 inches), wrapped in Dunlop tires, 235/35-19 at the front and 265/35-19 at the rear.
According to Wimmer, all these modifications will cost the owner around €19,900, which is about $28,156 based on current exchange rates. Add that to the price of the Mercedes C63 AMG and you’re looking at an $85,000 investment. Hey, that’s the price of cool and apparently the price of a weird yellow, white, and black paint job.
