Modified BMW M4 with 626bhp

Consider its MH4 GTR II, which is effectively a BMW M4 CSL with 692 horsepower and a bodykit that is completely black. Batman would feel self-conscious driving it.

For those who want to work on their M4 but don't want to give it the full "watch this" treatment, there may still be some chance.
Manhart acknowledges that "the eye-catching, extroverted appearance is not to everyone's taste" with the MH4 600 that you can see in the image above.

But, work is still being done on the 3.0-liter twin-turbo straight-six in the M4 Competition. A new ECU has increased power from the usual 503 bhp to an impressive 626 bhp and torque from 479 lb ft to 575 lb ft. A new stainless steel exhaust system is available, and H&R or KW lowering springs are an option.

Manhart adds that alterations to the appearance are wonderfully conservative, the engine is where it was allowed to "let off steam." The gorgeous gold-painted forged wheels, which measure 20 inches in front and 21 inches in back, as well as the carbon fibre front lip and side skirts are all from BMW's own M Performance Parts line.

Together with the rear diffuser and the little wing inserts in front of the doors, the carbon grille insert is an original Manhart design. We must acknowledge that none of the additions are objectionable. Though it must have been difficult for Manhart to resist adding a huge wing to the back, anticipate its next design to be completely insane.
