German tuner Hartge has released its tuning program and cosmetic upgrades for the 1 series M coupe.
For more power, the Hartge ECU tune for the 1M's N54 engine paired with its sports exhaust system pushes the 1M's power from the factory 335hp/332lb-ft to
396hp and
391lb-ft torque.
The resulting real-world performance increase? According to Hartge, their 1M goes from
0-200kmh (124mph) in 11.34 seconds (a 2.18 second decrease over the factory 1M's 13.52 seconds). On top of that, there's an increase in efficiency of 0.5L/km less consumption than the factory 1M.
Cosmetic aero parts include a trunk spoiler and roof spoiler.
