The German tuners over at Lumma Design are taking yet another stab on the BMW X6, this time, on the most powerful diesel model, the xDrive40d that is equipped with a twin-turbocharged 3.0-liter straight-six delivering 306-horses and 600Nm (442 lb-ft) of peak torque in factory tune.

After Lumma Design’s people get their way with the diesel unit by updating the software and adding a custom exhaust system, output is increased to a more hearty 340-horses and 670Nm (494 lb-ft).

Other performance-related modifications include the lowered sports suspension (-40mm) and the 22-inch lightweight alloy wheels wrapped around in 295/30-22 tires up front and 335/25-22 at the rear.

Next up is the exterior styling package that includes a wide body kit with a new front bumper sporting additional LED lamps, a blacked out grille, wheel arch extensions, side skirts with air vents, and a restyled rear bumper that makes place for a diffuser and the quad tail pipes.

Numerous carbon fiber parts such as the rear boot lid spoiler, mirrors caps, and headlamp trim complete the BMW X6’s exterior makeover.

The black and white color theme is continued inside with Lumma Design dressing the X6 in a mix of regular and carbon fiber-like leather, Alcantara and aluminum. In addition, there are independent front and rear sport seats with a backrest shells in structured carbon leather while the German tuner also added bespoke instruments and aluminum pedals.
