There it is: the new BMW M Coupé!…and almost at the same time we show our interpretation: the ACS4 Sport Coupé. To improve the driving dynamics we offer a modified rear axle ratio of 3.91 : 1 . This rear axle ratio guarantees greatly improved acceleration.

The response behaviour is improved thanks to the sports rear silencers. Made completely of special steel with chromed Racing tailpipes, they also provide a more sonorous note than the standard system. For the M-versions of the Z4 that are fitted with a twin sports silencer as standard, as well as the Twin Racing system there is a further option of Sports Trim Design.

This design is reserved exclusively for M-vehicles:

Faster and more precise gear shifts promote the adrenalin rush and perceptibly improve acceleration in a car. So the Short Shift has been adapted for the M-versions with manual transmission.

Extensive tests on race tracks and public roads have resulted in the development of a complete suspension concept consisting sports suspension, special antiroll bar kit and strut braces. In addition, exclusive to the M Roadster and M Coupé is a special racing suspension which is currently still in the development phase.

The suspension concept also includes the Type IV and, Type III alloy and racing rims. The M Roadster and M Coupé are even fitted with 9.0J x 20″ and 245/30 R 20 on the front and 10.0J x 20″ with 285/25 R 20 on the rear.

An aerodynamic package has been created which sets even more sporting accents. The package consists of carbon front spoiler elements that optionally can be joined to the front spoiler with chromed aluminium supports. In addition, the new chrome front grille gives the vehicles a trendy retro look and at the same time meets the high air flow demand of the 3.2 litre high revving engine.

The vehicle rear is enhanced with a fully integrated carbon rear diffuser. This diffuser is available with two different versions of the special rear skirt edge frame which, depending on which exhaust is fitted.

Of course there are a few fundamental differences between the Roadster and Coupé: for the Roadster the product range includes a chrome cover for the roll bars, a wind deflector in clear-glass style and a two-piece rear wing. For the coupé versions, a three-piece rear wing is available. Whatever the body version, the side skirts form the homogeneous link between the front and rear. A particular eyecatcher is the side deflectors with integrated flashers, which as an option can be supplemented with a Chromeline set.

Exclusivity is the trump card in the cockpits of all models: As well as the carbon interior trim in silver, and matching ergonomically designed airbag sports steering wheels, the accents are set above all by the aluminium accessories in silver or black anodized finish. There is also a pedal set with matching foot rest, a handbrake handle and a selector knob for the manual versions. Last but not least, foot mats with the AC Schnitzer logo, made from high quality velours, complete the range.
