Manhart’s MH3 GTR is the BMW M3 on steroids – 650hp, 800 Nm, & carbon Recaros

You may not like the M3’s controversial aesthetics, but German tuner Manhart has created a monster that you probably can’t refuse. It’s called the MH3 GTR, and it’s a juiced up version of the BMW M3 that produces a whopping 650 hp and 800 Nm of torque.

The company says that the MH3 GTR is a one-off unit only, and showcases Manhart’s latest interpretation of the power sedan. However, customers will be able to purchase the upgrades shown on the MH3 GTR individually, if you too wish to tweak your BMW M3 to a similar style and performance.

“How was the additional power gained?”, you may wonder. Thanks to an MHtronik Powerbox auxiliary control unit, an additional 140 hp and 150 Nm are further extracted from the S58 bi-turbo inline-six engine. Complementing the powertrain boost (and creating a more brutal sound) is a Manhart stainless steel exhaust system with valve control that ends with four 100-mm diameter tailpipes.

All the upgrades mentioned above are TÜV approved. TÜV, if you’re wondering, is short for Technischer Überwachungsverein in German, which means Technical Inspection Association. A TUV certification means a sampling of the product has been tested for safety and found to meet the minimum requirements of the German Equipment and Product Safety Act.

Customers outside of Germany can also opt for non-TÜV approved upgrades such as:

  • Otto Particulate Filter Delete
  • Gasoline Particulate Filter delete
  • Optional race downpipes without catalytic converter
  • Replacement pipes with 200-cell HJS catalytic converters
  • Sport downpipes with 300-cell GESi catalytic converters

To further improve road-holding and, of course, lower the car, the MH3 GTR also received a Manhart suspension upgrade, including a Manhart Variant 4 coilover suspension by KW Suspensions. Alternatively, customers can opt for a lowering kit with H&R springs. The brakes of the MH3 GTR have been kept stock, but individually configured upgrades are also available upon customer request.

Exterior upgrades on the MH3 GTR include a Manhart Carbon Diffuser, M Performance Carbon Front Spoiler, M Performance Carbon Rear Spoiler, M Performance Carbon Side Skirts, M Performance Carbon Aero Flicks, and a unique Manhart Decal Wrap.

Completing the look of the MH3 GTR are the Manhart Concave One rims, measuring 20x9J in the front and 20×10.5J in the rear, and shod in 265/30R20 rubbers in the front and 295/30R20 in the rear. On the inside, the MH3 GTR gets Recaro Podium Carbon Seats.

Pricing of the upgrades has not been revealed by Manhart, but interested customers can already contact the German tuner for the cost of each part. Most of the parts should also be compatible with the BMW M3 Touring and BMW M4.
