Based on the already exclusive BMW M4 DTM Champion Edition released in 2016, the 700hp MANHART MH4 GTR takes exclusivity to another level.
In contrast to what is usually the case with MANHART’s creations, the new model designation of the car in this case does not yet give any indication of its new performance value. Of course, the MH4 GTR still provides far more power than the 500 hp and 600 Nm of the base M4 DTM vehicle, which has been made possible thanks to water injection. The biturbo-fired S55 in-line six-cylinder engine has been given an ECU remapping in conjunction with a MANHART intercooler by CSF, as well as a MANHART carbon intake by ARMA, MANHART aluminium charge pipes and a MANHART stainless steel exhaust system with valve function.
The latter connects to the engine via MANHART “race” downpipes, which do not have TÜV approval due to the lack of catalytic converters and are only intended for export from Germany. All in all, this results in an output of 708 PS and 980 Nm, or 698hp and 723lb ft! In order to be able to continue to cope with its task without any problems despite the increase in power, the seven-speed dual-clutch transmission has also received a MANHART upgrade. The chassis and the formidable carbon-ceramic brake system remained untouched in the vehicle shown here – but MANHART also offers individual optimisations on request.
MANHART has also made changes to the car’s exterior, adding a carbon front spoiler with additional lip, a new rear wing and a carbon diffuser. An additional spoiler lip on the boot lid and exterior mirror caps – each from the M Performance Parts range and made of carbon – have also been added. Furthermore, the M4 was given an even more striking body styling, while retaining the original colour combination. The wheel arches now feature forged, in-house MANHART Concave One rims in 9×20 inch and 10.5×20 inch, covered with 255/35 and 295/30 tyres.
In the interior, there was also an unmistakable racing ambience even in its original state. MANHART have further enhanced this atmosphere with a steering wheel, upholstered in Alcantara from the M Performance Parts portfolio, Recaro bucket seats with partial leather upholstery and various carbon trim elements.7
