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 (516 kW / 702 PS), 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 (516 kW / 702 PS) and 880 Nm (649 lb-ft) thanks to the addition of the MHtronic auxiliary control unit. Those numbers represent a significant increase over the 543 hp (550 PS / 411 kW) and 650 Nm (479 lb-ft) 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 (4.3 inches) 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.
