BMW recently lifted the wraps off the first ever X3 M and X4 M performance crossovers. If, however, you can only afford a standard X4, German tuner AC Schnitzer has spiced up BMW's stylish sports activity vehicle with a host of carbon fiber components, new suspension, more power, and some interior tweaks. The result is a BMW X4 that looks like it's spent a lot of time in the gym.

Compared to the stock version, this modified X4 sits lower to the ground thanks to a custom suspension spring kit that lowers the nose by 0.78 inches and the rear by 0.98 inches, resulting in improved cornering ability. To improve the aerodynamics, the German tuner has fitted new front spoiler elements, a rear roof spoiler, rear trunk lid spoiler, and a carbon fiber Racing rear wing.

Other modifications include the rear skirt protection foil, custom side emblems and new engine optics. The modified X4 rides on AC1 BiColor or anthracite alloy wheels, available in 19-inch and 20-inch configurations. 22-inch AC2 alloy wheels are also available. Rounding off the exterior enhancements are AC Schnitzer 'Sport' carbon tailpipe trims, which can either be given the chrome treatment or blacked out. Inside, the tuner has added aluminum pedals, footrest, keyholder and an aluminum cover for the iDrive controller.

This isn't just a cosmetic upgrade, however, as the German tuner has also been tinkering under the hood and increased the power output. As standard, the xDrive30d version produces 261 hp, which has been increased to 310 hp, while the xDrive M40d version has been upgraded from 321 hp to 374 hp. Opting for the custom downpipe with sports catalytic converter with 300 cpsi for the M40i also provides better performance. No pricing details have been revealed yet, but this could be a more affordable alternative to the full-fat BMW X4 M.
