AC Schnitzer will be launching an upgrade program for the BMW M 135i this week at the Essen Motor Show.
In its standard configuration, the six-cylinder 3.0-liter engine produces 320 HP (235 kW) and 332 lb-ft (450 Nm) of torque, but after AC Schnitzer works its magic power is increased to 360 HP (265 kW) without increasing CO2 emissions.
They also have a custom suspension spring kit and various types of wheels in sizes up to 20 inches. A chromed "Racing" exhaust tailpipe is also available and a two-piece front spoiler. On the outside the M 135i can get a loading lip protection film, color-matched design stripes and a rear roof spoiler.
Moving inside there's an aluminum Black Line gear knob or you can choose the illuminated leather-wrapped gear knob. AC Schnitzer is also offering the Black Line aluminum cover for the i-Drive, another gear knob with a digital gear display, aluminum handbrake handle with chrome accents, custom velour floor mats and an aluminum foot rest.
