800-HP BMW M6 GRAN COUPE WORLD'S FASTEST AND MOST POWERFUL 6 SERIES

With the BMW M6 RS800 Gran Coupe, German tuner PP-Performance claims to have created the fastest, most powerful 6 Series in the world. Thanks to self-developed engine software optimization, special downpipes, an Akrapovic titan exhaust system and BMW racing filters, the M6 GC’s 4.4-liter twin-turbo V8 has been boosted to 800 horsepower and 701 lb-ft of torque, resulting in a top speed of 203 mph. The price of the upgrade package is 14,999 Euros, but there’s no word on whether any chassis or body mods have been made.
