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.
