Tradition demands it - every (2) years, at the International Motor Show in Frankfurt, as well as the many innovations in the AC Schnitzer special accessories range, a very special vehicle is presented. And 2003 is no exception: The Concept Car, the AC Schnitzer V8 Topster.
The basis is the BMW Z4 3.0i, in which however "no stone is left unturned". The most striking optical feature is the enclosed bodywork, now 13 cm wider, in colours orange / cream.
The life-giving organ which was developed in record time as a one-off special in close collaboration with the BMW works team Schnitzer Freilassing, is the upgraded performance version of the 4941 cc eight cylinder, four-valve engine from the BMW M5. In conjunction with our technology partner, the engineers have equipped the V8 Topster with special intake and exhaust camshafts. The cylinder heads have also been fine-machined, the compression raised to 11.5 : 1 and the control unit reprogrammed. To improve the exhaust gas flow, an environmentally-friendly special steel high performance exhaust system has been developed with twin chromed racing tailpipe trims in right and left combination.
In comparison with the M5, the power plant has had to be re-positioned in the engine bay of the Z4 basic vehicle and the entire oil circuit optimised, so it was necessary to modify the oil sump and oil pump. Finally, the air flow was improved. By means of new intake pipes and 2 air filter boxes, the entire intake tract could be optimised.
In motorsport the correct set-up is often decisive for a victory or podium place, and our development engineers place particularly great importance on optimum suspension settings. In the V8 Topster the driving dynamics are decisively improved by the special development of a 9-position adjustable AC Schnitzer racing suspension. As well as lowering by 35 mm in relation to its distant relation - the standard Z4 - the spring and damper rates have been substantially modified towards more sports performance. In addition the wheel bearings and front and rear control arms have been replaced.
The AC Schnitzer V8 Topster keeps contact with the asphalt through the brand-new racing rims Type IV. The sporting yet elegant 5-spoke wheels have particularly fine filigree work. The individual spokes which run star-shaped from the pentagonal wheel centre to the polished bed perfectly complement the avant-garde Topster outfit. But the wheel and tyre combination is not just an aesthetic highlight. With sizes 9.0J x 20" ET 18 with tyres 255/30 R 20 (front) and 11.0J x 20" offset 0 with tyres 305/25 R 20 (rear), the Topster can corner at speeds otherwise reserved for a thoroughbred Touring Car.
The interior of the AC Schnitzer V8 Topster is a combination of developments in the AC Schnitzer range available for many BMW models, and special one-off products. These include the racing bucket seats in leather. The airbag sports steering wheel, gear lever gaiter and handbrake cover are also provided in Alcantara with orange stitching. Velours foot mats also with orange applications and the leather logo round off the Topster interior.
The AC Schnitzer V8 Topster was developed as a technology showcase. In the equipment level and form shown here, this concept car would cost around € 185,000.00. Series production is not planned.
