Manhart keeps launching more powerful variants of the M3/M4 with the latest being based on the track-focused BMW M4 CSL. The Manhart MH4 GTR II has a monstrous power output of 692 hp, combined with extensive visual modifications that make it look like Darth Vader’s vehicle of choice – well, that or a modern ’66 Batmobile with all those red pin stripes. The MH4 GTR II is probably the most extreme-looking tuned M4 yet, mostly due to the high-contrast red accents and Manhart’s 18-piece carbon body kit. The latter includes a prominent splitter, canards, a vented hood, side skirts, diffuser extensions, and a rear spoiler, all made of carbon fiber. Interior upgrades include special floor mats, Schroth four-point racing harnesses for the M Carbon full bucket seats, a Clubsport roll bar, and a carbon-fiber motorsport helmet for track days.
The MH4 GTR II sits on a new set of
20-inch forged alloy wheels by Yido Performance finished in Matte Black with
two orange-red spokes. The rims are shod in mixed tires measuring 275/30/R20 at
the front and 295/30/R20 at the back. The car is lowered thanks to the addition
of new height-adjustable H&R coil springs. For those who are not satisfied
with the carbon-ceramic brakes of the stock M4 CSL, Manhart is also offering
the option of upgraded brakes.
More importantly, the tuned twin-turbo
3.0-liter inline-six engine produces 692 hp and 880 Nm thanks to the addition of the MHtronic auxiliary control unit. Those numbers
represent a significant increase over the 543 hp and 650 Nm of the stock CSL, making the MH4 GTR II the most powerful BMW M4 in
Manhart’s current range.
The Wuppertal-based tuner added its own
stainless steel exhaust system with quad carbon or ceramic-coated 110 mm tailpipes. There is a choice between sport downpipes, racing downpipes
without catalytic converters, or OPF Delete replacement pipes. The BMW M4 CSL
has a limited production of 1,000 units, which is why Manhart is also offering
the option of building the MH4 GTR II on the far more widely available BMW M4
Competition. Interested parties can contact the tuner directly for pricing and
availability of the aforementioned modifications.
