When the BMW 6 Series Gran Coupe was launched, everyone was amazed by the way it looked. It's, simply put, the most beautiful BMW model out there, at the moment. However, those 2 extra doors meant some added weight.
More controversy came when BMW decided to launch the 2 tone car with a 3-liter petrol engine, even if it was turbocharged. With 'only' 320 HP and 450 Nm (332 lb-ft) of torque coming out of those 6-cylinders, people thought this will be a slow car.

Real life tests though, proved them wrong. The 640i has plenty of punch to reach 100 km/h (62 mph) in 5.4 seconds and go all the way up to a top speed of 250 km/h (155 mph).

Kelleners Sport prepared a tuning kit for the 4-door Coupe though, which we presented a while back. Now, they are showcasing the acceleration abilities of a tuned up 640i, using their technology.

According to official information, the Kelleners Sport kit adds 54 HP to the 320 stock ones and some 77 Nm of torque, creating one hell of a fast car, as you can see in the video below.
