The most recent BMW M3 Competition is tuned by the German tuner Manhart, who tweaks it to produce the unique MH3 GTR. The manufacturer completely modifies the powertrain, suspension, and aesthetics of the quick sedan.
The S58 3.0 liter twin-turbo inline-six continues to be used in the MH3 GTR. The output is increased to 641 horsepower (478 kilowatts) and 590 pound-feet of torque using Manhart’s MHtronik auxiliary control unit. This is a significant improvement over the factory-specified 503 horsepower (375 kW) and 479 lb-ft of torque (650 Nm).
Additionally, Manhart provides many exhaust enhancements. The typical configuration consists of four 3.9-inch (100-millimeter) diameter tips, four stainless steel pipes with valves to control sound, and stainless steel pipes. The outlets can alternatively be had with a ceramic or carbon coating.
The tuner offers a racing setup sans cats, sports downpipes with 300-cell catalytic converters, and an Otto particulate filter deletion with 200-cell catalytic converters. However, Manhart sells the components for export despite the fact that they lack TÜV approval for usage on German roads. .
The MH3 GTR should be able to handle the road slightly better than the already outstanding M3 Competition. The purchaser has a choice between a lowering kit with H&R springs and the Manhart Variant 4 Coilover configuration using KW components.
Manhart doesn’t change the brakes. However, the tuner is happy to make those modifications if the buyer of the MH3 GTR requests them.
The firm adds a few minor aesthetic changes to the M3 Competition. The hood, back deck, and trunk lid of the MH3 GTR are all lighter gray with a dark gray body. The body receives carbon components for the diffuser, side skirts, rear lip spoiler, and aero flicks at the front corners.
The car is supported by six-spoke wheels that are 9×20 inches in the front and 10.5×20 inches in the back. In these pictures, they have a satin black finish, but Manhart can produce them in any color the customer wishes.
Recaro Podium front seats with a complete carbon-fiber shell are the only interior upgrade. Under the headrest, there is an embossed Manhart logo.
Manhart’s announcement is mum on the cost of the MH3 GTR. For comparison, a 2023 M3 Competition costs $77,695 with rear-wheel drive and $81,795 with all-wheel drive (after the $995 destination fee).
