Porsche reveals new 911 GT3 R racer
Based on the road-going 911 GT3 RS, the new GT3 track car features better aerodynamics, improved handling and lower service and spare-parts costs.
Porsche has revealed a new 911 GT3 R customer race car to compete in GT3 events around the globe.
The new track car has been adapted from its latest road-going counterpart, the 911 GT3 RS, with a wheelbase that has been stretched by more than three inches compared to the previous generation. The revised geometry is said to improve weight distribution, bringing more predictable handling in fast corners.
Engineers have worked to lower the center of gravity and shed weight overall, thanks to a combination of aluminum, steel and composite materials. The 'double bubble' roof, front cover and fairing, wheel arches, doors, side and tail sections are all produced from carbon-fiber, while the windows and windshield consist of polycarbonate.
The engine is mostly identical to the 4.0-liter flat-six found in the GT3 RS, producing at least 500 horsepower and 339 lb-ft of torque. Power is sent to the rear wheels via a sequential six-speed paddle-shifted transmission.
The company has worked to improve the brake system to better handle long-distance racing, increasing stiffness and tweaking the ABS system. The 380mm slotted front discs are grabbed by six-piston aluminum calipers, while four-piston calipers latch onto 372mm discs attached to the rear axle.
Drivers will benefit from a new safety fuel cell, which now holds 120 liters of gasoline, while the roof escape hatch has been enlarged. The new racing bucket seats are also said to offer better protection in collisions.
Porsche is now taking orders for the 911 GT3 R, with prices starting at 429,000 euros (~$490,000 USD).
