Here we have another tuning kit for the BMW 5-Series brought to us by Kelleners Sport. The works are included in the package, consisting of a new aero kit, performance tuning, suspension parts, and interior improvements. The German tuner did a proper tuning job with this M sport BMW 5-series. Power has been boosted around 20 percent for all models under the 5-series. Starting with the 520d, figures increased to 218 PS and 450 Nm of torque, while the 535i now puts out 367 PS and 480 Nm of torque.
