Geneva 2015: Hamann BMW M4

Art and ability – that is the link between Swabian car refiner Hamann and designer Timo Wuerz (42) whoses latest “moving work of art” has been revealed at the Geneva Motor Show in form of the M4 sports coupé individualised by Hamann.
The largest German national subscription daily newspaper, Süddeutsche Zeitung once called the creative genius the “rock star of the comic scene”. The designer, who made Hamburg his city of choice, individualises cars and lifestyle products, turning them into unique pieces bearing his distinctive touch. As homage to the art of engine construction, the colours of the “M” logo served as source of inspiration.
Exclusively for the Hamann sportscar, Wuerz has created a fulminant energy explosion, perfectly setting the stage for the vehicle concept’s characteristics. The work was transferred to the car on a sophisticated printed wrap.

Hamann’s “aerodynamics upgrade” basically dominates with its extravagantly shaped bonnet made of visible carbon fibre and the potent rear wing in GT3 style. 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.

The standard M4 which comes with 431 hp is anything but underpowered – but Hamann wants more. The car refiner 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 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. 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.
