Exactly what was done to the 4.2L V8 inside the M3 isn't clear, but the ECU has been tweaked to yield a gain of almost 6%, likely from adjusting fuel ratios and ignition timing. The power gain takes the car's top speed up to a frightening 202mph (325km/h). The only exterior tweak is a set of 19in BBS alloy wheels.
Inside, the car gets, as its name indicates, a thorough treatment of upgraded leather. Leather seats plus suede headliner steering wheel and door panels give the car a soft yet sporty look, while aluminum pedals give the driver even better feel, while contrasting stitching in BMW's traditional colors complements the darker surfaces.
