With the new generation BMW M3 Sedan and M4 Coupe currently arriving in showrooms, Manhart thought that it would be a good idea to preview what they’re planning for the two performance models from Bavaria. The aftermarket upgrades are not ready yet, so they have released official illustrations to provide us with a glimpse of what to expect in the coming months.

Named the MH3 600 and MH4 600, the tuned M3 and M4 will sport the company’s MHtronik Powerbox and one of two exhaust systems available, each one with twin carbon fiber tailpipes, which raise output and torque to around 620 PS and 750 Nm respectively in the Competition variants. By comparison, the stock models have 510 PS and 650 Nm produced by the twin-turbo 3.0-liter straight-six. A similar upgrade will also launch for the regular M3 and M4, increasing their power from 479 PS to around 590 PS.

 

A set of lowering springs made by H&R will bring the bodies of the new M3 and M4 closer to the ground by a few millimeters, while leaving room under the arches for the aftermarket wheels. Developed in-house by Manhart, the Concave One forged set measures 9×21-inch at the front and 10.5×21-inch at the rear, wrapped in 265/30 and 305/25 tires respectively.

Further boosting the visual presence will be the carbon fiber bonnet, front splitter, rear diffuser, spoiler and side flaps, while the golden accents on the outside, which can be specified to the rims too, round out the looks. This will be the so-called ‘phase 1’ of the tuning program, but Manhart is also working on a ‘phase 2’, which it claims will take the M3 and M4 “to the next level”, so we’ll definitely keep an eye open for it.
