Manhart Racing, a German tuner responsible for some of the craziest tuning jobs including a V10 engine transplant for BMW Z4, has come up with a plan for BMW X6M. Due to the depth of the modifications, they no longer recognize it as a BMW and decided to forgo calling it the X6M and instead refer to it as the Manhart M6XR Biturbo.
The deepest modifications have been done on the car’s 4.4 liter win-turbo engine. With standard output of 555 hp and 680 Nm, this engine by no means is boring, but with the Manhart package it will be capable of producing an incredible 687 hp which is better! They’ve done it by fiddling with the engine electronics, including DME control, and a catalytic conversion including modifications to the converters.
As a result this 2380 kg monster achieves a power to weight ratio of 3.4 kg per hp which means it can do 0 to 100 km/h in 4.7 seconds, and achieves an unbelievable top speed of 319 km/h. But if that’s still not enough for you, Manhart has a 700 hp version in the works, equipped with new exhaust manifolds, and capable of 900 Nm torque.
Other features of this car include new stainless steel exhausts system with four 90 mm tailpipes and two 200-cell HJS racing catalytic converters, Four Manhart RS sports rims (11J x 23 in size and fitted with 315/25 ZR23 tyres), high-end braking system with 395 mm discs and six-piston calipers at the front, and 375 mm discs with four-piston calipers at the rear, and sport suspension which lowers the car by 30mm.
As for the interior, they can offer a full-leather package with Alcantara roof and door linings, and Klavierlack double-coat clear finish trimmings.
