Hartge introduces their own BMW 1M. The Little M now produces 420 horsepower from the standard 340 ponies.
The German tuner offers a tweaked ECU and stainless steel rear silencer with dual round tail pipes (diameter 80 mm) giving the standard 3.0-liter twin-turbo engine with its 340 HP (250 kW / 335 bhp) and 500 Nm (369 lb-ft) of torque a new power output level of 401 HP (295 kW / 396 bhp) and 530 Nm (391 lb-ft).
For reference, Manhart’s kit for the 1M produces 420 HP (309 kW / 414 bhp) while both RevoZport’s and TechTec’s makes 450 HP (336 kW / 444 bhp), to name a few.
Other upgrades included in the Hartge program are 30 mm lowering sports springs, boot lid spoiler, roof spoiler, aluminum pedals and HARTGE floor mats in black velour.
