German firm AC Schnitzer has unveiled a fresh tuning package for the BMW X3 M Competition, handing the performance SUV extra power, an aerodynamic kit and interior modifications.

The tuned X3 M Competition’s 3,0-litre twinturbo-petrol inline-six has been tweaked to produce a whopping 441 kW and 700 N.m (up from 375 kW and 600 N.m), which is sent to all four corners via BMW’s rear-biased xDrive all-wheel-drive system.

Other mechanical modifications include a suspension-lowering kit, which drops the mid-size performance SUV by “approximately” 20 to 25 mm, while an aerodynamic package improves overall downforce. The latter includes a revised front splitter and a rear roof-mounted spoiler replete with an integrated wing.

The Aachen-based firm also offers two sizes of wheels. The X3 M Competition can be specified in either 20- or 22-inch light-weight alloys, wrapped in Michelin rubber. Other exterior fitments include rear-skirt protection film and AC Schnitzer emblems.

Inside, myriad items have been finished in aluminium, with the most notable being the pedals, iDrive controller and shift paddles.
