According to BMW the M4 limits of physics are its only enemy. Until now.
Laupheim, 18 November 2014. It is something very special, this F82. Not only because it comes with a roaring turbocharged six-cylinder engine, but also because its overall concept actually allows free play to the claim of being a sports car. According to the Bavarian manufacturer the limits of physics are its only enemy. Until now. This fit occasion the refiner and tuning expert from Laupheim, Hamann Motorsport, did not want to miss: The Swabian interpretation of the “M” sports car faces the standard M4 in a more than self-confident manner. Thus, Hamann once again follows the customers’ demand for even more individuality than the manufacturer’s personalisation options allow.
The muscular GT3-design rear wing sitting enthroned on a light-alloy profile immediately catches the eye. The aerodynamic component featuring sides made of visible carbon fibre dominates the rear and underlines the status as purebred sports car.
The one-piece carbon bonnet with dynamic beads also attests this: the partial coating in car body colour allows for an exclusive view of the high-tech material. At the front, it is Hamann’s creation with carbon-fibre spoiler lip that impresses – a striking detail that will not only send motorsport fans into transports of delight. The elegantly profiled aerodynamics part increases the downforce as in the GT Sport. It is an attention-grabbing contrast to the standard model’s chunky air intakes and reaches as far as the wings’ edges. The specialists from Laupheim continue this clear line with pronounced side skirts. In true Hamann style, the standard rear is pepped up by a diffuser with four massive carbon winglets, offering a striking setting for the four-pipe exhaust system. Even the tailpipes the refiner does not leave untouched: the German tuning manufacture finishes off its work with carbon-fibre tail pieces with a diameter of 90 mm that proudly bear the noble Hamann brand mark.
Although the standard M4, which comes with 317 kW (431 hp), is anything but underpowered, you cannot go wrong with more. Hamann fulfils the strong desire of racing fans and Nürburgring enthusiasts with a special control module for electronic power advancement that waits under the bonnet, if desired. It increases the engine power output to impressive 380 kW (517 hp) and presses forward heavily: at 1 850 - 5 500 rpm, Hamann makes the V6 turbocharged engine produce a maximum torque of 700 Nm – 150 more than the standard model features. With these acceleration values, the modified M4 should be at least one step ahead.
For making this power controllable it is also necessary to modify the suspension: Hamann brings down the vehicle’s centre of gravity by around 30 mm, not only giving the car a racy look. Additionally, the experts from Laupheim use reinforced sport anti-roll bars that optimise the steering behaviour and reduce body roll. The precise adjustment to the adaptive M suspension guarantees that the M4 is not thrown off the track, even near the limit – given that the right wheel/tyre combination is used.
The 21-inch “Anniversary Evo” light-alloy wheel’s multi-spoke design comes with a glossy black finish. High-performance Vredestein Ultrac Vorti R tyres passed the car refiner’s tough tests with flying colours. On the front axle, Hamann relies on 9.0 J x 21 ET 32 wheels combined with tyres in size 245/30 ZR21. The rear axle impresses with 305/25 ZR21 tyres and “Anniversary Evo” wheels in 11.0 J x 21 ET 50. In the experience of the Hamann developers this combination convinces by best handling characteristics and excellent acceleration and deceleration values when combined with the M carbon ceramic brakes.
Also the interior cannot do without that certain something: hence, sport pedals made of black anodised aluminium, and exclusive floor mats made of high-pile velours from Hamann’s interior programme are essential elements. Those looking for that special something will be delighted with the car door LED welcome projector lights with Hamann logo. The high-quality and tailored Hamann components for the M4 are available now individually or as complete set. Hamann refines the cars at its headquarters in Laupheim as well as at international partner sites.
Performance values stated above may vary depending on engine type, the vehicle’s equipment, gearbox, transmission ratio, wheel/tyre combination. To achieve optimal performance with petrol engines, Super Plus 98 ROZ or higher petrol types need to be used.
