The 2011 Porsche 911 GT3 RS 4.0 certainly has the stats of a kick-ass track car. Who can argue with a naturally aspirated, 4.0-liter flat-six with 500 horsepower, an 8,250 rpm redline and a Nürburgring time of 7:27? Just as exciting is the fact that the GT3 RS 4.0 weighs only 2,998 pounds soaking wet, thanks to a host of weight-saving measures like light-weight carpet and scads of carbon fiber. And when was the last time you saw a street-legal production car with front dive plates for added down-force?
