German tuner, PP-Performance, are claiming to have created the fastest, most powerful BMW 6-Series in the world. It is called the BMW M6 RS800 Gran Coupe and thanks to some self-developed engine software, downpipes, Akrapovic exhuast system and BMW racing filters, the 4.4-litre twin-turbo V8 now puts out a whopping 800 horsepower. This results in a top speed of 203 mph (325 km/h). No word on the 100 km/h sprint but I am guessing this is rather impressive too! To finish off the look, they painted the car in what I would call electric lime green.
