800-HP BMW M6 Gran Coupe Tuned by PP-Performance

German tuning firm PP Performance has presented an upgrade package for the BMW M6 Gran Coupe, billed as the fastest 6-Series in the world. The numbers backing up the claim: a boost in power from 560 hp to 800 hp 700 lb-ft of torque, and a top speed of 203 mph (versus a stock speed electronically limited to 155 mph, or 189 mph when configured with the optional M Driver's Package). The V8 4.4-liter twin-turbo engine remains the same, with the power upgrade achieved by installing bespoke downpipes, BMC racing filters, an Akrapovic titanium exhaust system and a series of electronic tweaks.
