When I drove the BMW X6 M I made it very clear that it was not underpowered but for the likes of Manhart, it is never enough. The 4.4-litre biturbo V8 that sits under the hood produces 567 horsepower and 750Nm in stock form but thanks to a tuning package from these madmen, it now pushes out a whopping 690 hp and 950 Nm of torque. The extra beef came thanks to a remapped ECU and an aftermarket exhaust system with modified silencer and new downpipes. They have renamed the beast MHX700 and an estimate of the 0 to 100km/h time is 4.0 seconds flat. Performance upgrades means cosmetic upgrades which include a new carbon fibre bonnet and 22-inch Concave One wheels. The same package can be purchased for the just as rapid BMW X5 M.
