A few weeks ago we saw the first purported leaked stats on Porsche's uber-GT3, the RS 4.0, and about ten days ago, an image followed via the same enthusiast forum. Yesterday, we got a few more details on the car making the rounds, and today brings interior images. We can't verify the authenticity of the information or the images, but they certainly look legit.

Inside, we see the fabric door pulls and predictably spartan yet loud-colored interior. Hit the link below for more interior images at Teamspeed. On the outside, little canards along its front fascia and a larger rear wing mark the RS 4.0 as the ultimate send-off to the current 997-generation car before the whole 911 range replaced with the upcoming 991.

The GT3 RS 4.0 will also purportedly include painted carbon fiber hood and trunk panels, riveted RSR-style widened front and rear wheel arches, no choice of PDK dual-clutch gearbox, and an 8,500-rpm rev limit.

The leaked option sheet reads like a GT3 RS shopper's wish list--aside from the price. Starting at 149,990 euros, or $217,350 translated to 'Merican greenbacks (a process that's not always so direct in practice), it's a pricey purchase. But it may justify the expense.

The rumors of a 4.0-liter, 500-horsepower Porsche GT3 RS started brewing back around the 2010 Paris Auto Show. Rumored to be a 500-unit, limited-edition model according to the purportedly leaked document, the GT3 RS 4.0 has yet to be officially confirmed by Porsche.
