Origins: motorsport.
Where our inner self comes to life.
Prototype racing.
Prototypes are pure-bred race
cars that are not based on road-
legal production sports cars.
For example, the RS Spyder, built
to LMP2 (Le Mans Prototype 2)
requirements. In 2009 – after
the stipulated reduction of the air
restrictor – its 3.4-liter V8 racing
engine delivered 440 hp. The total
vehicle concept is based on a low
center of gravity, excellent traction
and a low weight. The result is an
impressive success story.
Out of 42 races driven, by the
middle of 2009, the RS Spyder
had achieved a total of 32 class
wins and 11 overall victories.
