    Over 600 hp and carbon styling for the Munich SUV coupé

    Almost exactly 15 years ago, BMW presented the Concept X6 as a representative of a new crossover genre – a mixture of SUV and coupé. Despite initially sceptical reactions, BMW did not allow itself to be deterred and proved the doubters wrong with the successful production model. Today, we are two X6 generations further on, and there are numerous imitators as well as little brothers from our own company: one class lower, the X4 has also been delighting customers and petrolheads for eight years – especially in the M-top version available since 2019. It is the latter that has attracted the attention of the MANHART Performance team in the first place.

    It now serves as the basis for our latest creation: the MANHART MHX4 600. The team pushes the three-litre S58 biturbo straight-six to 635 hp and 785 Nm of maximum torque. Our team achieves this plus of 125 hp and 135 Nm compared to the standard values of the X4 M Competition either with the help of our proven MHtronik powerbox or by ECU remapping.

    In addition, a MANHART stainless steel exhaust system with valve control is on board, which flows into four 100 mm tailpipes with ceramic or carbon coating. If desired, it connects to the power unit via MANHART race downpipes without catalytic converters or MANHART sport downpipes with 300-cell catalytic converters. However, like the OPF/GPF Deleter and the OPF Delete replacement pipes with 200-cell HJS catalytic converters, which are also offered, these do not have TÜV approval and are thus only intended for export.

    The brake system, which is already stable ex works, remained in standard condition on the example shown, but individual upgrades are possible on request.

    The suspension, on the other hand, has been optimised by us, including a lowering by H&R springs by 30 millimetres. The resulting even sportier, individual look is underlined by our eight-piece carbon exterior kit: it includes a front spoiler, two-piece front skirt add-ons, two-piece front skirt inlets as well as mirror caps and a rear diffuser.

    In addition, the MHX4 600 wears the typical MANHART decal set on its black body. Matching red trim lines the wheels. These are multi-spoke MANHART wheels by ALPINA in 9×22 and 10×22 inch with 255/35 and 295/30 tyres. Alternatively MANHART offers the Concave One wheels in 9×21 inch offset 20 and 10.5×21 inch offset 40 with 265/35 and 305/30 tyres.

    Last but not least, the interior in this case remained unchanged in its richly carbon-fibre standard state. However, we can also implement individual refinements here on request.
