German tuner Hartge takes BMW's 3.0 liter, twin turbo diesel to 328 hp and 675 Nm of torque on the X6 xDrive35d. That takes this X6 from 0 to 100 km/h in under 6 seconds, about a full second quicker than the standard model.

Right on the heels of the X6 M debut comes German tuner Hartge with a boogie-fied version of the monster SUV/Coupe. But tuning is all about the little details and this X6 xDrive35d diesel comes with a few fine flourishes.

The twin-turbo 3.0 liter diesel gets a working to the tune of 328 hp and 675 Nm of torque. That brings the 2,185 kg mass that is the X6 from 0 to 100 km/h in under 6 seconds, as opposed to the standard model's time of 6.9. Hartge has measured the derestricted maximum speed at 256 km/h.

But the engine work is only a small part of the story. The aerodynamic kit made of PUR-RIM, an ultra-lightweight polyurethane plastic, helps make that sprint time and top speed possible. The kit includes a front spoiler and skirt at the back beholding an integrated diffuser and stainless-steel tailpipes in a quadrilateral shape. A Hartge suspension set also lowers the X6 by 30 mm.

All this is riding on Hartge's 22-inch "Classic 2" wheels fitted with 295/30ZR22 at the front and 335/25ZR22 tires at the rear. On the inside is a series of carbon paneling and parts, including a 3-spoke Hartge leather steering wheel.

The full Hartge package for the X6 xDrive35d will set you back 29,353.94 euros, all parts and labor included.
