BMW M3 and M4 lifted to 612bhp by Manhart Performance 

German tuner Manhart Performance has extracted more power from BMW’s new M3 and M4

The new BMW M3 and M4 are only just beginning to hit the road, but tuner Manhart Performance has already developed a tuning package ready to take things up a notch. Due to be available later this year, it pairs a boost in performance with its own bespoke carbonfibre aerodynamic components.

The two models are called MH3 600 and MH4 600, and starting under the bonnet Manhart has extracted 612bhp and 552lb ft of torque from the S58 straight-six engine in both the M3 and M4 Competition models. Applying its €2299 MHtronik piggyback ECU module, various parameters such as boost pressure are altered in order to lift output without hardware modification, adding 109bhp and 74lb ft of torque over BMW’s factory power figures.

Performance is predictably impressive, with the 0-155mph sprint now happening a whole 4 seconds sooner than in a standard M3 Competition at 17sec – 62-124mph also now comes at a brisk 6.42sec, with 0-124mph at 10.5. Once the all-wheel drive models become available later this year, expect that 0-62mph time to drop even further. 

Manhart has also released details of a new exhaust system, with an OPF-back or cat-back versions to choose from. All come with quad carbonfibre-wrapped exhaust tips, with buyers able to option a middle silencer replacement pipe should they want. New systems are priced from €1399 without a catalytic converter, rising to €4449 for the slip-on ‘Sport’ system with valve control.

A new carbonfibre bonnet, front splitter, rear spoiler and diffuser are among the aerodynamic modifications available, as well as H&R lowering springs, 21-inch in-house wheels and brake upgrades. For €4869, Manhart will also equip the model with adjustable KW suspension tuned for the German firm.  

Manhart says it has plans to offer a more comprehensive performance upgrade further down the line, too, and with the S58’s proven resilience to tuning expect some big numbers when Manhart starts playing with the hardware.
