With its 635 hp, the recent BMW M5 CS is already the most powerful of its long line. But for the German trainer Manhart, unsurprisingly, this is not yet enough. Presented at the Munich Motor Show, its new MH5 GTR therefore brings the twin-turbo V8 to 788 hp.
At BMW, the letters GTR evoke a very special M3 E46. For questions of homologation in progress, it was the only one of its generation to receive a V8. In the road version, there are only 10 copies, which makes it one of the rarest models in the history of the brand. But the new MH5 GTR from German tuner Manhart is even more exclusive. Based on an already unusual M5 CS, this sedan would indeed be quite simply unique.
A story of color and rims
Presented at the next Munich Motor Show in early September, this 5 Series unlike any other first stands out with its rather threatening look. The body is not however deeply modified. She is simply dressed in a dark blue film with a matte appearance, with a gray strip and different stickers. While eliminating the few golden touches that are present on the original M5 CS. Another (large) size change: new 21-inch Manhart rims, fitted with wide 295/30 ZR 21 tires at the rear. Wedges have also been added to ensure that these wheels come up to the wing.
153 hp more for the V8 4.4 biturbo
The visual impact of this MH5 GTR also comes from its reduced ride height, made possible by the installation of adjustable handsets signed KW. However, this is the only modification made to the chassis of this M5 CS, whose lighter interior also seems to remain original. As on the new M3 and M4, the German preparer preferred to put his hands under the hood, to install one of his Powerbox electronic boxes and a Powerbox air box as well. The twin-turbo 4.4 V8 thus climbs from 635 hp to 788 hp, and from 750 to 935 Nm of torque. A more sonorous exhaust is also part of the game, with various options available. One of them will however only be available for export, as it also includes the removal of the particulate filter imposed by European standards.
Not the most powerful of the range
To request an approval from TÜV, the German certification body, Manhart will therefore not rely on this solution. But he remains confident about his chances of succeeding in obtaining this precious sesame across the Rhine. If the MH5 GTR is unique, like the MH4 GTR based on the M4 GTS DTM Champion Edition which preceded it and which will also be exhibited in Munich, then nothing will prevent asking for the same mechanical modifications for their own M5 CS. Moreover, on the basis of a “simple” M5 Competition, the preparer already offers an even more muscular MH5 800, with 815 hp and 1,030 Nm.
