Known for tuning powerful BMWs, Manhart have now worked their magic on the X6 M.

Baptized the MHX6 700, the range-topping SAV has received a software optimization, stainless steel muffler with valve control and larger tailpipes, and downpipes with 300 Cell Catalysts, which push the 4.4-liter twin-turbo V8 to 700PS (690hp) and 900Nm (664 lb-ft).

The extra oomph represents a 125PS (123hp) and 150Nm (111lb-ft) increase over the stock BMW X6 M, and slashes something off the 4.2sec needed for the 0-100km/h (62mph) sprint, although we’re not exactly sure how much, as the tuner has yet to release any such numbers.

Besides squeezing more power from under the hood, Manhart have also added a few visual tweaks to the already flashy vehicle. These include a front spoiler, bonnet with new air inlets, trunk lid-mounted spoiler, and rear diffuser, all of which have been made from carbon fiber. Meanwhile, the 10,5×22-inch and 11,5×22-inch front and rear wheels, wrapped in 295/30 and 335/25 rubber, round out the list of updates on the outside.

Before calling it a day, the company has also made some chassis improvements, and added an H&R lowering kit, thus improving the BMW X6 M’s cornering abilities, in theory, at least.
