The car tuning firm Kelleners Sport have now released another package for the BMW 5 Series M, which tunes both the 535i and 520d models. These cars will displayed at the upcoming Geneva Motor Show, and Kelleners guarantees a 20 percent gain of power for the petrol and diesel engines. For the petrol powered 535i, the power output was raised from 306 hp to 367 horsepower, with torque increased from 400 to 480 Nm. Meanwhile, the 520d diesel engine was boosted from 184 hp to 218 horsepower, and a final torque output of 450 Nm. Styling modifications for the BMW 5 Series M came next.

At the exterior level, Kelleners tuning added their own aftermarket parts with a mesh grille, new surrounds, rear diffuser, oval tailpipes, and a rear spoiler. On all fours you will find a new set of rims measuring 20×9 in the front, and 20×10 at the rear, wrapped in high performance tires. Inside the modded BMW 5 Series cars, the tuning company hooked it up with new pedals, footrests made of polished aluminum, and a set of real velour black floor mats with the tuner’s logo. Covering the seats is black leather upholstery with white stitching to contrast.
