The 911 GT3 RS 4.0, a flagship offering from Dr. Ing. h.c. F. Porsche AG, Stuttgart, epitomizes one of the most esteemed, sought-after, and triumphant lineages in racing pedigree production cars. Limited to just 600 units, this model amalgamates all the characteristics that have rendered the Porsche 911 GT3 a consistent champion on racetracks. Boasting a motor derived from thoroughbred motorsport technology, its engine inherits the crankshaft directly from the 911 GT3 RSR racing car's six-cylinder engine, while its forged pistons' connecting rods are crafted from titanium. This four-liter displacement powerhouse stands as the largest engine ever fitted to a 911 model, delivering a formidable 125 hp/liter (92 kW) - the most potent naturally aspirated engine yet, producing a peak power of 368 kW (500 hp) at 8,250 revolutions per minute, accompanied by a maximum torque of 460 Newton meters at 5,750 rpm.

The 911 GT3 RS 4.0 showcases remarkable performance, demonstrated by its astonishing lap time of 7:27 minutes around the Nürburgring-Nordschleife. With a six-speed sports transmission as standard, it accelerates from 0 to 100 km/h (62 mph) in just 3.9 seconds, reaching 200 km/h (124 mph) in under 12 seconds, thanks to its track-oriented gearing.

The driving dynamics of the 911 GT3 RS 4.0 are meticulously honed, with careful attention to detail. Utilizing suspension components akin to those found in motorsport, weight reduction is paramount. Standard equipment includes lightweight components such as carbon fiber bucket seats, bonnet, and front wings, plastic rear windows, and weight-optimized carpets, resulting in a curb weight of just 1,360 kilograms with a full tank of fuel. With a power-to-weight ratio of 2.72 kg/hp, the 911 GT3 RS 4.0 dips below the coveted threshold of 3 kilograms per hp.

Painted in standard white, the limited-edition 911 GT3 RS 4.0 exudes a dynamic presence, emphasizing its racing heritage. Signature features include a wide track, low stance, prominent rear wing with adapted side plates, central twin tailpipe, and aerodynamically optimized body. Innovative lateral front air deflection vanes, known as "flics," debut on a production Porsche, enhancing front axle downforce alongside the steeply inclined rear wing, ensuring aerodynamic equilibrium. At top speed, these aerodynamic enhancements provide an additional 190 kg of downforce, keeping the 911 GT3 RS 4.0 firmly planted on the road.

The market release of the Porsche 911 GT3 RS 4.0 commences in Germany in July 2011, priced at 178,596 euros.
