BMW Z4 M Coupé as motor racing kit.

The first BMW two-seater for Nordschleife fans and international
customer teams. Munich/Geneva, 27th February 2006. Unveiling in
Geneva: On the occasion of the Automobilsalon, Prof Dr Burkhard
Göschel, BMW Group Board Member Purchasing and Development,
introduced a new racing car for customer motor racing. The Motorsport
Version of the BMW Z4 M Coupé, which has already made a big
impression as a production model, is the first two-seater BMW Motorsport
offers for customer teams. When it came to the development, BMW faced a
huge challenge: The car had to have what is needed to race successfully
on the world's most demanding and spectacular racetrack, the
Nürburgring's famous Nordschleife. The new motorsport coupé
can be used by private BMW customer teams in the German Endurance
Championship and in the Nürburgring 24-Hour Race. The power unit
of the beefy coupe is a BMW Motorsport designed 3.2-litre in-line
6-cylinder engine delivering about 400bhp, with the suspension area in
particular benefiting from the knowledge gained from the successful BMW
M3 GTR project. With its varied component ranges, BMW Motorsport and
BMW Racing Parts Distribution offer customer teams a new technology
platform for use in many miscellaneous international racing and club
sport series, with the Nordschleife enthusiasts not being the only
interested party, as the brawny coupe also represents the perfect car
for use in the Belgian Belcar series and other, non-European, endurance
series. The kit can be ordered from May 2006 at BMW Motorsport and
will be available for an estimated € 250,000 (plus VAT).
