The Porsche RS Spyder was designed and built specifically to compete in the the 24 Hours of Le Mans, American Le Mans and Le Mans racing series, where it falls under the Le Mans Prototype 2 (LMP2) class. Sponsored teams include the Penske Racing Porsche RS Spyder, and the Porsche race car continues to notch up wins, both class wins and overall wins, in endurance racing series around the world. As per LMP2 regulations, the Porsche RS Spyder has an engine displacement of just under 3.4 Liters, and runs on 10 percent bioethanol fuel.

The German-sourced race car has had great success in the American Le Mans racing series, taking home more wins in the LMP2 class in recent years than any other competitor. According to official American Le Mans racing series documentation, Porsche is the only manufacturer with an entry in the series which can claim that their Porsche RS Spyder Le Mans cars are built on the same assembly line as the Porsche German sports cars offered to the buying public.

Far from being just about bragging rights and drumming up interest, the Le Mans endurance racing series the Porsche RS Spyder competes in are about testing new technologies which hope to trickle down into Porsche, and other competitors' parent companies, consumer model lines.

Because the LMP2 Porsche Spyder competes in the prototype class, rather than the GT classes, Porsche is not required to produce RS Spyder-spec cars for road use, as is the case with BMW's M3 GT2 endurance racing cars or Porsche's own 911 GT3 Cup Car, for example. Still, prototype endurance racing is an exciting sport, which gives automakers a chance to try out their newest technologies on the world stage.
