Porsche's latest race version of its 911 GT3 RSR has a little bit more power and a few other tweaks, mainly in aerodynamics, meant to cement itself as the perfect selection for the race team with $550,000.

The tale of the tape: 455 hp at 7,800 rpm, 332 lb-ft of torque, 9,400 rpm redline. The front was reshaped for greater downforce, and the rear/wing package chiseled as well. Those who splurged on a 2010 can also buy a kit with the '11 updates.
