Both Rockenfeller and Luhr are products of Porsche’s “Star of Tomorrow” program and bring a wealth of success, despite their young ages. Rockenfeller spent 2006 racing in the Grand-Am Rolex Sports Car Series for the Alex Job Racing Ruby Tuesday Championship Porsche Crawford Daytona Prototype and also in the American Le Mans Series for AJR in a Porsche 911 GT3-RSR. Luhr competed with Penske Motorsports in the brand-new Porsche RS Spyder, winning the LMP2 driver’s championship with longtime co-driver Sascha Maassen.
In 2007, Rockenfeller and Luhr will make their debut in the DTM but will also compete in some sports car events with the R10 TDI.
