BMW 1-Series by Hartge

Hartge has introduced a new tuning program for the BMW 1-Series (F20). On the styling front, the model can be outfitted with lowering springs (which reduce the ride height by 30mm) and 19-inch alloy wheels. The cabin can also be equipped with aluminum pedals, velour floor mats and Hartge badging. For added performance, a revised ECU enables the 116d to produce 142 PS (104 kW / 140 hp) and 310 Nm (229 lb-ft) of torque. Likewise, the 118d can be tuned to develop 174 PS (128 kW / 172 hp) and 380 Nm (280 lb-ft) of torque. Lastly, the optimized ECU for the 120d allows the engine to produce 218 PS (160 kW / 215 hp) and 450 Nm (332 lb-ft) of torque.

Hartge H35d based on BMW 535d

German tuner Hartge (which, like Alpina, is officially certified as a manufacturer in Germany) has turned the 300 PS (220 kW / 296 hp) BMW 535d (F10) into the Hartge H35d with 354 PS (260 kW / 349 hp) and 700 Nm (516 lb-ft) of torque.

Hartge also adds its own sport springs which lower the suspension on the car by 30 mm and fits its with 21-inch, ten-spoke wheels.

The stainless-steel rear silencer with 80 mm dual tailpipes helps provide this oil-burning powerhouse with just the right muted diesel sound.

The outside gets a few delicate touches such as the carbon casings for the side mirrors. For the interior are several other light trims which include the aluminum pedals and stainless-steel door sills.
