2005 AC Schnitzer ACS5

This M5, pictured in standard form, has been perfected by the German tuner AC Schnitzer. This meant also that some components did not need perfecting – this applies primarily to the powerful engine. The V10 high performance machine remains unchanged even after the AC Schnitzer treatment.

Only in the area of the exhaust system attached to the engine did AC Schnitzer see room for improvement. The newly developed AC Schnitzer double sports rear silencer made completely from stainless steel and finished with the equally new chromed tailpipe trims in ‘Sports Trim’ design, gives the BMW M5 a far more powerful and sonorous voice than its standard brother. At the same time, the gas flow is optimized and the response behavior perceptibly improved.

The ‘Sports Trim’ rear silencer is an exclusive development for the new BMW M-series – not only for the M5 but also for the M6.

The driving dynamics of the BMW M5 are further improved by the use of the AC Schnitzer suspension spring kit. As well as simply lowering the vehicle by around 1 inch, which lowers the centre of gravity of the BMW M5, the spring kit allows spirited cornering in the M5 with no loss of driving comfort.

In addition, the BMW M5 can be fitted with racing rims and alloy wheels in various designs and sizes. One absolute highlight in the AC Schnitzer wheel sector is the new Forged Wheel. This lightweight forged wheel with bi-color finish – i.e. partly polished, partly lacquered surface achieves an apparent fundamental paradox: reduction in weight, and at the same time maximum wheel diameter and width. This masterpiece is achieved by the AC Schnitzer engineers and designers in the “Forged Wheel”, whose design – although unmistakably related to the Type IV wheel – is totally unique. The Forged Wheel is expected to be available from December 2005 in sizes 9.0J x 20” and 10.0J x 20”” for the BMW M5 and will be fitted with tires of size 245/35 R 20 or 285/30 R 20 on the rear.

Although the appearance of the vehicle already becomes more exclusive by fitting the AC Schnitzer wheels, we also offer aerodynamically efficient modifications to the bodywork.

For the M5, a carbon front splitter has been developed which can be firmly attached to the front spoiler with chromed aluminum webs. This individual solution not only gives the sports saloon a more striking outfit but also improves downforce on the front axle. In addition, the new AC Schnitzer chrome front grille can be fitted, which naturally meets the high air intake requirements of the BMW V10 engine. At the same time it gives the BMW M5 a touch retro look, reminiscent of a legendary “shark’s mouth”.

Aerodynamic balance is achieved by the rear roof spoiler, the one-piece rear spoiler and the carbon rear diffuser which is integrated into the rear skirt. The latter also impressively integrates the AC Schnitzer sports rear silencer Sports Trim.

Used in conjunction, all aerodynamic aids ensure higher downforce for the BMW M5, so that with the entire AC Schnitzer aerodynamic conversion the vehicle is perceptibly more stable and its appearance harmonizes with its sporting performance ambitions.

For the interior, a carbon interior trim is available in titanium “Exclusive” finish, a 3-spoke sports airbag steering wheel or velours foot mats together with the characteristic AC Schnitzer aluminum pedals and footrests or the handbrake handle.

The new design of an aluminum cover for the controller of the BMW i-Drive System in the design of the Type IV wheel sets the finishing touch.

The complete AC Schnitzer special accessory range for the BMW M5 is expected to be available from Winter 2005.
