BMW M5 with 660HP by Kelleners Sport revealed image

The German aftermarket specialists at Kelleners Sport have revealed a new upgrade package for the BMW M5 F10.

According to the German tuner, the new BMW M5 has been named the KS5-S and the powerful vehicle is now developing a total output of 660 horsepower from the same engine, which has been tweaked in order to allow the model to reach a top speed of over 330 km/h. Kelleners Sport didn’t announce the performance figures of the new BMW M5 KS5-S, but in standard version, the German car was able to accelerate from 0 to 100 km/h in just 4.3 seconds, before reaching an electronically limited top speed of 250 km/h.

Besides the power boost offered by Kelleners Sport, the BMW M5 has also been fitted with a sports suspension and a new exhaust system, but the exterior design of the German vehicle hasn’t been left aside either and the overall look of the model is even more aggressive. Kelleners Sport says that the BMW M5 F10 is now sitting on 20-inch alloy wheels and the cabin has received new leather upholstery and special stitches. Unfortunately this is all the info we’ve got on the KS5-S for the moment, but as a small reminder, the standard BMW M5 F10 is getting 560 HP from a V8 twin-turbo engine.
