2012 Porsche 911 GT3 RS 4.0
With the 2012 Porsche 911 GT3 RS 4.0, one of Dr. Ing. h.c. F. Porsche AG, Stuttgart’s most popular, coveted and successful racing pedigree production cars is entering the home straight. Limited to 600 vehicles, the Porsche 911 GT3 RS 4.0 brings together in a road car all the attributes that have made the Porsche 911 GT3 a serial winner on the race track.
The new 911 GT3 RS 4.0 is a thoroughbred vehicle, uncompromisingly optimised for handling, with the performance of all vehicle components, including the suspension and aerodynamics, specially synchronised. Its true performance potential is especially evident on racing circuits: It makes it round the Nürburgring-Nordschleife in 7:27 minutes. With its gearing designed for the racing circuit, the 2012 Porsche 911 GT3 RS 4.0, available exclusively with a six-speed sports transmission, reaches the 200 km/h (124 mph) mark in under 12 seconds.
The 2012 Porsche 911 GT3 RS 4.0‘s outstanding driving dynamics are the fruit of meticulously coordinated details. In addition to using the suspension components typically encountered in motor racing, weight reduction is also of supreme importance. Equipped as standard with lightweight components such as bucket seats, bonnet and front wings made of carbon fibre, plastic rear windows and weight-optimised carpets, the two-seater’s ready-for-road weight is a mere 1,360 kilograms with a full tank of fuel. At 2.72 kg/hp, the Porsche 911 GT3 RS 4.0′s power-to-weight ratio thereby dips below the magical threshold of three kilograms per hp.
The limited 911 edition is painted white as standard and emphasises its proximity to motor racing by its dynamic appearance. Trademark characteristics are the wide track, the low vehicle position, the large rear wing with adapted side plates, the typical central twin tailpipe and the aerodynamically optimised body. The lateral front air deflection vanes, socalled flics, making their first appearance on a production Porsche, testify to the aerodynamic precision engineering. They create increased downforce on the front axle and together with the steeply inclined rear wing bring the vehicle into aerodynamic equilibrium.
The most powerful naturally aspirated engine of all the 911s The Porsche 911 GT3 RS 4.0′s six-cylinder, naturally aspirated engine saw the light of day under the tutelage of the Porsche engineer team, also responsible for racing car development. The four-litre engine offers motorsport technology to its innermost core. The flat engine’s crankshaft has been lifted unchanged from the 911 GT3 RSR racing car’s six-cylinder engine and the forged pistons’ connecting rods are crafted from titanium. True to the highrevving concept, the engine is designed with a short-stroke; with a bore of 102.7 mm each cylinder’s stroke is 80.4 mm, thus ensuring a compression ratio of 12.6:1. The four-litre displacement sports engine, the biggest ever sports engine in a production 911, is Porsche’s most powerful naturally aspirated engine with 125 hp/litre (92 kW). It achieves its maximum power of 368 kW (500 hp) at 8,250 revs per minute. The maximum rpm is 8,500.
The engine delivers its maximum torque of 460 Newton metres at 5,750 rpm. The new Porsche 911 GT3 RS 4.0 is also fitted as standard with a sport button in the front centre console. Pressing this button increases the torque in mid-range engine speeds by up to 35 Nm. But the maximum torque remains unchanged. The increase in torque is achieved by additionally reducing the exhaust back pressure in the sports exhaust system and the associated improvement in the gas cycle.
