|The top-of-the-line Porsche 911, the GT3, is scheduled for a world premiere at the upcoming Geneva Motor Show. (click to enlarge)|
Exterior-wise, the GT3 bears the iconic look of the 911 and is instantly recognizable. The flagship 911’s overall look sustains all the successful properties of a sports car suitable for racing, with even more driving dynamics, more sophisticated practicality, and a highly emotional fun factor. The 911 GT3 is 44 millimeters wider than a 911 Carrera S in the area of the rear axle. Another clear recognition feature is again the large, fixed rear wing. Contact with the road is made by the new 20-inch forged alloy wheels with central locking.
Porsche 911 GT3 smashes Nurburgring record in under 7:30
Bred for the racetracks, the Porsche 911 GT3 in its 5th-generation guise takes up a new body and chassis combination which stemmed from the 911 GT3 Concept. It promises an even more awe-inspiring on track experience. Previous track runs have entailed that the 911 GT3 managed to set numerous performance records, especially at the recent Nurburgring run where the then Concept version garnered an impressive lap time of under 7:30.
The powertrain of the new 911 GT3 is composed of a 3.8-liter boxer engine yielding 475 hp at 8.250 rpm, a Porsche dual-clutch transmission (PDK) and a high-traction rear-wheel drive. The six-cylinder engine is based on the same engine as the 911 Carrera S. All other components, particularly the crankshaft and valve gear, were specially adapted or designed for the GT3. For instance, Porsche designed titanium connecting rods and forged pistons. The basic modifications set the stage for a high-speed engine that reaches up to 9,000 rpm. The Porsche dual-clutch transmission was also specially developed; the characteristics are directly based on a sequential gearbox from motor racing, thereby providing further performance and dynamics advantages to the driver. A maximum speed of 315 km/h is achieved in the seventh, top gear of the PDK transmission.
With a power to weight ration of just 3kg/hp, the 911 GT3 goes from 0 – 100 km/h in 3.5 seconds and achieves a top speed of 315 km/h. The 911 GT3 features the Active Rear Wheel Steering in a production Porsche for the first time. The purpose is to achieve even higher precision and lateral dynamics. Depending on the speed, it steers in the same or opposite direction of the front wheels, improving stability and agility. Other new modules improving driving dynamics are the electronically controlled, fully variable rear differential lock, dynamic engine mounts and an all-aluminium adjustable chassis.
