Rumormill: Porsche sending off 997 with 500-hp 911 GT3 RS

Just when you thought that the Porsche 911 GT3 RS couldn't get any more enticing, word crops up that German sports car manufacturer has a new special edition planned. If the buzz cropping up over at Teamspeed is to be believed, Stuttgart is working up a special edition RS to end all RS models. The car will be limited to just 500 units, each one packing a heady 500 horsepower from a 4.0-liter mill. That represents a 50 horse jump over what's available in the standard GT3 RS and 65 more ponies than the "base" GT3.

The news comes courtesy of Teamspeed member AlexG, who despite the urging of his fellow forum members, won't share his source. Even so, the GT3 RS Limited Edition is supposed to make use of the same flat-six engine found in the mighty RSR. Pricing is supposed to fall well below the 911 GT2 RS but above the standard 911 GT3 RS. We're guessing that the sticker will fall somewhere close to $200,000 if/when it goes on sale in July 2011.
