RS Spyder wins with new direct fuel injection (DFI
Successful race premiere for the new direct fuel injection (DFI) race engine from Porsche: Timo Bernhard (Germany) and Romain Dumas (France) won the LMP2 class at the sixth round of the American Le Mans Series in Lexington/Ohio with the engine that was run for the first time in the RS Spyder. With this, they further increased their lead in the championship. For the reigning champions this marked the fourth victory so far this season, and the third in a row on the demanding Mid-Ohio Sports Car Course.
Like the standard units in the Cayenne and the 911, power was increased and fuel consumption decreased - an important element of endurance racing. Instead of 478 hp, the new racing power-unit has an output of 503 hp (370 kW) at 10,000 rpm. Maximum torque rose from 370 Nm at 7,500 revs to 385 Nm at 8,500 rpm.
The new engine of the Porsche RS Spyder is the first with direct fuel injection technology that can rev to more than 10,000 rpm. During the development of the engine, synergies in the areas of standard and motorsport design were utilized to a large extent. Above all, in the calculation and evaluation of the engine many important details were developed jointly.
