The Manhart MH4 GTR II is a high-performance version of the already potent BMW M4 CSL, developed by German tuning company Manhart. Exclusivity of this model is assured as only 1 000 units of the CSL are destined for production, and we imagine that few of those folks are going to mod their cars.

Power Up

Under the vented hood of the Manhart MH4 GTR II is the same twin-turbocharged 3,0-litre inline-six engine as it leaves the factory. However, it has been extensively modified by Manhart. The result is an impressive 516 kW and 880 N. of torque. This is a significant increase over the stock M4 CSL’s 405 kW/650 N.m. The bulk of this power increase comes from the company’s own MHtronik piggyback ECU.

The Manhart MH4 GTR II also features other performance enhancements. These include a new stainless steel sports exhaust system that can breathe with or without catalytic converters. The system ends in a quartet of pipes that measure a whopping 110 mm each. The company also offers an upgraded brake kit to match the extra power.

Added Menace

On the outside, the MH4 GTR is visually striking, with a number of aggressive styling cues that set it apart from the standard M4 CSL. The most obvious is a vented carbon-fibre bonnet. In addition there is a new splitter and side aero flicks for the front, fender side louvres, side skirts, a diffuser, a two-piece rear skirt add-on and a three-piece rear spoiler.

The car sits on a set of lightweight forged alloy wheels that are 20 inches in diameter. The ride height is lower thanks to height-adjustable coil springs by H&R. The overall effect is a car that looks mean and purposeful. 

Track Ready

Manhart has added motorsport-inspired features to the already racy cabin, such as SCHROTH four-point racing harnesses, and provides a carbon fibre motorsport helmet for those who wish to venture onto a track.
