Press Release) Press Release - Manhart Racing M6XR Twin Turbo
Bold statement: 687 hp & 319 km/h!
Doubtless, it takes some
degree of nerve to approach a vehicle of the calibre of an X6 M. The
über-SUV is powered with a V8 twin turbo engine as standard, which
develops a fat 555 hp and 680 Nm of torque at a maximum charging
pressure of 1.5 bar. And when liberated from its burdensome
electronic speed limiter, the X6 has the capability to run up to a
speed of 275 km/h. Impressive performance specifications -
equivalent to those of a supercar.
Doping for the V8 twin turbo!
Günther Manhart, of
course, is not impressed by those numbers; he has been something
akin to an inofficial pope at BMW motors for many years. Thanks to
his many years of experience with the Bavarian engine constructors,
the X6 M V8 twin turbo engine proved no exception to his ability to
quickly find efficient ways of increasing the performance of an
engine. Thanks to an overhaul of the engine electronics, including
DME control, and a catalytic conversion including modifications to
the converters, the power of the 4.4 litre V8 is increased to 687
hp, which at a tare weight of 2380 kg amounts to a power to weight
ratio of 3.4 kg per hp. With that, the Manhart M6XR sprints to 100
km/h from a standing start in just 4.7 seconds, and achieves an
unbelievable top speed of 319 km/h. A version with more than 700 hp
is planned within a short time which, equipped with new exhaust
manifolds, will break the 900 Nm barrier.
Something that is also conducive to the power of the car, of course,
is the new stainless steel exhaust system, with four 90 mm tailpipes
and two 200-cell HJS racing catalytic converters. Four Manhart RS
sports rims ensure optimum contact with the bitumen, all at 11J x 23
in size and fitted with 315/25 ZR23 tyres. With the sports chassis,
developed and manufactured by Manhart, the centre of gravity of the
X6 M is approx. 30 mm lower, which is of particular benefit to
handling in tight corners. Optimum deceleration of the 2.4-tonne
sports SUV is ensured by a 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.
There is the option of a full-leather interior with Alcantara roof
and door linings, to go with the characteristically clinical
interior of the X6 M, as well as numerous Klavierlack double-coat
clear finish trimmings.
