When the GT3 RS 4.0 debuted in 2011, it was the ultimate naturally aspirated 911. Its 4 liter flat-6 was the largest in a 911 to that time, and the same displacement sees use in the newer 911 GT3 RS. With 500 hp, it produces a full 125 hp per liter from a naturally aspirated engine.
Weight optimization measures included a carbon fiber hood, bucket seats, and front wings, as well as plastic rear windows and lightweight carpet. At just under a svelte 3,000 lbs, the RS 4.0 makes it round the Nurburgring-Nordschleife in 7:27 minutes.
Standard configuration on the GT3 RS 4.0 is the white paint and design shown. Aerodynamic components include the large rear wing, and the first use of lateral front air deflection vanes on a production Porsche.
This car will be sold by Mecum Auctions in Monterey, California on August 18-20, 2016, right before the Pebble Beach Concours d'Elegance on August 21.

Porsche GT cars development chief Andreas Preuninger’s experienced team dedicated themselves to turning out the ultimate GT3, the 2011 GT3 RS 4.0, as a final salute to the so-called “Mezger engine” that began life in the 1996 Le Mans Porsche GT1. Preuninger specified the highest-displacement engine ever installed by the factory in a 911, a 4.0L flat-6 that also features the highest output in a naturally aspirated Porsche flat-6, 125 horsepower per liter. That’s right: 500 horses at 8,250 RPM and 339 lb-ft of torque at 5,750 RPM, conjured by combining the crankshaft from the 911 GT3 RSR race car with titanium connecting rods, forged aluminum pistons, reconfigured valve timing and free-breathing center exit exhaust. Creating the über GT3 RS also meant packing the car with the full mix of proven aero, body and chassis tweaks and racing-purposed suspension pieces. A 6-speed manual transmission and huge vented-rotor carbon-ceramic disc brakes were imperative, as are the extra-wide center-lock 19-inch alloy wheels and Michelin Cup tires. Extensive use of lightweight components, including carbon-fiber engine intake box, front fenders, luggage compartment lid and sport bucket seats, along with weight-optimized carpets, result in a road-ready weight of just 2,998 pounds with a full fuel tank. Finished in special Carrara White paint with red-on-gray accents, the GT3 RS 4.0’s forceful presentation results from its low stance, wide footprint and full-race aerodynamics that incorporate the signature large rear wing mounted at a 9-degree angle. Its effect is balanced by the first front-dive planes ever used on a production Porsche, resulting in 426 pounds of extra downforce at Porsche’s claimed top speed of 193 MPH. Offered with stereo sound with Bluetooth connectivity, adaptive sports seats with memory and a Porsche Certificate of Authenticity, this 2011 Porsche GT3 4.0 is one of just 600 examples of the car widely regarded as the best 911 ever.
