Introduced in 2007, the performance-oriented 997 GT3 RS built upon the foundations of its 996 forebear and served to homologate its racing counterparts for FIA competition. Porsche’s thirst for continuous improvement yielded two subsequent generations of the 997 GT3 RS – the GT3 RS 3.8 in 2010, and then, in 2011, the final-evolution GT3 RS 4.0, which was built in a run of 600 units.
Overseen by Andreas Preuninger, Porsche’s director of GT car development, the RS 4.0 offered many upgrades over previous models. Making their first appearance on a production Porsche, air-deflection vanes mounted on either side of the front bumper increased downforce on the front axle. In conjunction with a more steeply inclined rear wing, the aerodynamically enhanced GT3 RS was effectively pushed to the road with an additional 426 pounds of downforce at its 193-mph top speed.
The largest-displacement 911 engine to date, the four-liter M97 flat-six used the forged pistons and titanium connecting rods found in the 997 GT3 RSR race car. Delivering 500 hp at 8,250 rpm and 339 lbs./ft. of torque, the engine set benchmarks for a naturally aspirated 911 powerplant.
To pare weight, the GT3 RS 4.0 was equipped with carbon fiber bucket seats, front fenders, hood, and lightweight carpet. Weighing in at 2,998 pounds “wet” with fuel, Porsche said the new model weighed 200 pounds less than the outgoing car and had an incredible weight-to-power ratio of 5.99 pounds per horsepower.
Combined with numerous suspension refinements and equipped with a sixspeed manual transaxle with shorter gearing optimized for track duty, the GT3 RS 4.0 could sprint to 60 mph in 3.8 seconds and hit 124 mph in 12 seconds, according to the factory.
The 997 GT3 RS 4.0 offered here is one of 158 earmarked for the North American market. It was delivered new in March 2012 to Bob Moore Porsche-Audi in Oklahoma City and sold to its first owner, Steve Bowers of Arizona. Finished in Carrara White, this RS was trimmed in contrasting black and red leather and Alcantara, and outfitted with numerous additional options including Porsche’s ceramic composite brakes, Sport Chrono Package Plus, PCM 3.0 with extended navigation, Sirius XM Radio, and adaptive sport seats with an MSRP of $203,595.
Maintained by the current owner’s in-house Porsche technician and showing little signs of use, this GT3 RS 4.0 displays less than 160 miles on its odometer and is accompanied by its books, keys, and a CARFAX Vehicle History Report. Capable of providing truly exceptional performance on and off the track, this example will undoubtedly please the most discerning of collectors.
