Three models of BMW’s X6 luxury crossover SUV have undergone performance upgrades at the hands of German tuners Hamann Motorsport, who recently debuted the Tycoon. The xDrive35i’s inline six-cylinder engine has been upped to 360 hp from the stock 306 hp. Both diesel models of the X6 have been similarly tweaked. The xDrive30d now has 261 hp instead of the base 235 hp, and the xDrive35d has been tuned to deliver 316 hp instead of the stock 286 hp. Worldcarfans also reports the tuner has performance planes for the top-of-the-line X6, the xDrive50i. The car’s presence has also been modified with a new body kit which features new front wings, rear wing extension, apron with air intakes, LED daytime running lights and Hamann’s own Race Anodized ultralight 23-inch rims.
