If you were ever in any doubt that Manhart is one of the best BMW tuners out there, then its latest effort will sway your way of thinking.

The tuner took the X6 M — which by the way is already an impressive specimen packing 567 horsepower from that burly 4.4-litre biturbo V8 — and sure upped the ante on the BMW.

Called the MHX6 700, Manhart remapped the ECU and added a new exhaust (with 300-cell catalyst downpipes) to help it produce a whopping 690 horses.

Although no 0-100kph time has been mentioned, it must be quicker than the regular X6 M, which manages the dash at 4.3 seconds. The H&R lowering springs not only reduce the ride height but improve the handling and the bespoke bodykit gives it a more muscular look.
