The first few 2012 Porsche 911 GT3 RSR racers have made their first appearance in the United States, ahead of their competition debut in the the American Le Mans Series. Although the machine is labeled with the 2012 designation, the latest GT3 RSR is actually still based on the 997 model, not the latest 991 variant of Porsche's long-running 911 model range.
When Porsche launches a new 911, it doesn't just launch one model, it starts a process that will see literally dozens of variants to follow. Some with turbos, some without. Some with all-wheel drive, some driving just the rear. Coupes, convertibles, targas, lightweight models, and yes, even racing versions.
