Porsche's 911 GT3 R: The Public's Race Car
|   Thursday, June 11, 2015
The assertion of the title is not a euphemism but represents the plain truth: the GT3 R Porsche is a model developed for those who want a car compatible with GT3 racing category.

Within the 24-hour race at Nurburgring, Porsche presented the racing version of the 911 GT3 RS series model, called the 911 GT3 R. The new racing car has a lot of improvements over the previous 911 GT3 RS, which was based on the 997 body. It has a new 991 body with an increased wheelbase, lower center of gravity and better aerodynamics.


The starting point was a Porsche GT3 RS, after which engineers have done everything possible to cut as much of the weight of the car as possible. Another important aspect was to improve the car's aerodynamics and reduce fuel consumption, prices for maintenance and spare parts.

As was expected, the car handling was another key issue. The people at Porsche choose to increase the GT3 R's wheelbase by 8.3 cm for better distribution of loads when cornering and more intuitive behavior.

Overall, Porsche engineers have been focused on reducing weight. The body structure remained aluminum and steel, like the production car, while basically all exterior elements, including doors, 2-meter long 40-cm wide aileron, wings, the engine cover and roof, were all made of carbon fiber bringing the weight down to 1,220 kg. Also, all windows, and for the first time the windscreen, are made of polycarbonate.

The new Porsche 911 GT3 R is powered by a naturally aspirated 4.0-liter engine with 6 cylinders which transmit more than 500 horsepower to the rear wheels. The engine is almost identical to the one on the of series car, 911 GT3 RS, with dry sump lubrication system and is paired to a 6 speed sequential transmission. The engine uses direct injection, which operates at a pressure of 200 bars and a variable valve technology to optimize fuel consumption.

For times when power has to be cut, the brakes on the Porsche 911 GT3 R received monobloc aluminum calipers with six pistons in front and four in the back, and 380 mm brake discs on the front axle discs while 372 mm discs are fixed on the rear axle so the pilot is absolutely secure when driving this monster.

And for times when the brakes are not enough and there is no other solution the emergency exit, the roof was enlarged. Also, the reservoir volume has been increased by 12 liters to 120 liters.

On the outside the car benefits from ventilation intakes in the hood and front fenders, and in the back we have the opportunity to admire the racing diffuser and the impressive deported wing that maintains Porsche tradition of efficiently using this aerodynamic element.
The cockpit is very Spartan with a single sports seat protective cage and lots of cables and buttons that ensure the best possible operation of all mechanisms and systems.

Among the rivals of the new Porsche 911 GT3 R we have racing cars like the Mercedes-AMG GT3, Lamborghini Huracan GT3 and GT3 McLaren 650S. Pilots eager to acquire the new Porsche can already order it, paying no less than 429,000 euro. Order now and get the first copy in December 2015.
