BMW Motorsport has torn the wraps of its ready-to-race two seater. Designed for
enthusiast customers who ache to post a competitive time at the famed
Nordschleife as much as for professional touring and production car race teams
around the world.
The new BMW Z4 M Coupé by BMW Motorsport was unveiled at the Geneva Motor
Show last week by Prof Dr Burkhard Göschel, BMW Group Board Member Purchasing
and Development.
The Motorsport Version of the BMW Z4 M Coupé, which itself has only just been
revealed in production guise, is the first two-seater BMW Motorsport has offered
for customer teams.
The development plan was simple: Design a car to race successfully and
spectacularly on the world’s most demanding 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 coupé is a development of the BMW Motorsport
designed 3.2-litre in-line six-cylinder engine, delivering about 400bhp (300
kW), with the suspension in particular benefiting from the knowledge gained from
the successful BMW M3 GTR project.
Plenty of race-adjustable components have been designed into the car by BMW
Motorsport and the BMW Racing Parts Distribution. Customer teams now have a new
technology platform for use in many diverse international racing and club sport
series. Fans of a fast-paced trip around the feared Nordschleife are not the
only targets, since the hairy-chested coupé 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 from BMW Motorsport and will be
available for an estimated
euro 250,000 (plus VAT).
