Porsche 911 GT3 R race car unveiled
Lighter, faster and more efficient Porsche 911 GT3 R revealed at the Nurburgring
A lighter, faster and more economical Porsche 911 race car has been revealed at the Nurburgring, ahead of the gruelling 24-hour race this weekend.
Based on the new 911 GT3 RS, the track-ready 911 GT3 R has been created with a focus on lightweight design, aerodynamic efficiency and improved handling. Porsche says it has further optimised safety, as well as lowering the GT3 R’s service and repair costs.
Featuring the distinctive double-bubble roof, the R has a wheelbase extended by 83mm over its predecessor. The result is a more even weight distribution and more predictable handling.
The GT3 R uses an adapted version of the GT3 RS’s rear-mounted 4.0-litre flat-six to develop more than 500bhp. Porsche says the omission of a turbocharger offers “significantly better drivability and a broader useable rev range.”
Power is sent to the rear wheels via a sequential six-speed constant-mesh gearbox, controlled via a pair of steering wheel mounted paddles. All cars also get a mechanical limited slip differential.
In terms of aerodynamics, the GT3 R gets a huge, two-metre rear wing and distinctive wheel arch air vents. Engineers have repositioned the radiator for a better centre of gravity, while also improving cooling via louvres in the front.
The brakes have been overhauled, too, with six-piston aluminium monobloc callipers and 380mm ventilated discs at the front. At the rear, all cars get four-piston calliprers with slightly smaller 372mm discs.
But the changes don’t stop there. The GT3 R is safer than the car it replaces, thanks to a reinforced safety cell, fuel cut-off valve and more protective seats. The escape hatch in the roof has been made larger too, while both the doors and side windows can be removed in the event of an accident.
The GT3 R is available to order now, priced at €429,000 (around £310,000). First deliveries are expected from December 2015.
