Laupheim, 24 October 2017. In the comparative test of trade journal AUTOBILD Sportscars, Hamann Motorsport came off with convincing performance: on the High-Speed Oval in Papenburg, the M4 Coupé of the Swabian car refiner reached a speed of 306.4 km/h. Thus, the optimised M4 was the fastest BMW on the track. All test results can be read in the current issue no. 11 of AUTOBILD Sportscars.

The turbocharged six-cylinder engine of the M4 is the perfect basis for the high-performance vehicles of the power pros from Laupheim. Thanks to an additional control unit Hamann converted the standard M4’s 317 kW (431 hp) into impressive 380 kW (517 hp) at 700 Nm – 150 Nm more than with the standard version. Thus, the Hamann Coupé already broke the 250-km/h barrier 1 000 metres after the start. After a further 1 000 metres, the speedometer showed 290 km/h. And then the grand finale after 3 000 metres: 306.4 km/h!

To safely master this performance, the car refiner lowered the chassis and installed sport anti-roll bars for the M suspension. The overall concept also includes the aerodynamics kit comprising a carbon-fibre spoiler lip, a striking GT rear wing and a diffusor with four carbon-fibre winglets. Equipped with Hamann’s 20-inch “Anniversary” wheel rims and high-performance tyres from Continental approved for up to 340 km/h, the M4 by Hamann went into the competition with a powerful wheel/tyre combination.

The test centre in Papenburg ranks among the world’s largest, producer-independent car testing grounds. The ultimate highlight on the 800-hectare site: a 12.3-kilometre oval track with two steep curves. The AUTOBILD Sportscars test was supported and documented by engineers of TÜV Rheinland. The professionals of Racelogic used a VBOX 3i GPS data logger for the measurements.
