Porsche 911 GT3 R: Fast and Furious

Porsche has designed a new racing vehicle for customers competing in 2019 GT3 championships around the world, the 911 GT3 R, which is based on the 911 GT3 RS serial production.

Porsche 911 GT3 R: Fast and FuriousDuring the development of this "nine-eleven" competition with 550 horsepower (404 kW) has paid particular attention to aerodynamic efficiency and further optimization of safety, as well as reducing the costs of repairs and spare parts.

The lightweight bodywork of the standard 911 GT3 RS, made of composite with a clever mix of aluminum and steel, has proven to be the ideal basis for the new racing car, which is very similar to the road.

On the GT3 R, the roof, front hood and fairing, wheel arches, doors, some side and rear sections, as well as the rear hood and interior trim are made of especially lightweight carbon fiber composite material (CFRP). ). In addition, all the windows are made of polycarbonate.

The new 911 GT3 R is powered by an advanced four-liter boxer engine, which is practically the same as that used in the road-approved 911 GT3 RS. Direct fuel injection, which operates at pressures of up to 200 bar, as well as the adjustable valve opening times of the intake and exhaust camshafts, guarantee highly efficient fuel utilization.

In addition, compared to its predecessor, the naturally aspirated engine offers greater ease of use and a wider rev range. Engine response is more accurate due to the six throttle butterflies. The power from this rear engine is transferred to the 310-millimeter-wide rear wheels via a six-speed, stepless gear, Porsche sequential gearbox with an electronic shift actuator for shifting from gear to gear. be very fast and accurate.

As in the road-approved GT models, the driver changes gears by means of paddles positioned in the most suitable way on the steering wheel. The clutch function is automated, eliminating the need for a clutch pedal and aiding in quick starts in the race. Typical of the 911, the weight distribution ensures excellent traction and outstanding braking performance.

The spectacular aerodynamics of the 911 GT3 R also follows the example of the road car. The distinctive front wing vents increase downforce on the front axle.

Measuring 1.900 millimeters wide and 400 millimeters deep, the rear wing provides aerodynamic balance. The tire circumference on the front axle has grown from 650 to 680 millimeters. In conjunction with the new Porsche double wishbone suspension, it ensures greater braking performance, which remains constant throughout the race.

The 911 GT3 R's brake system also undergoes various modifications and now offers superior stiffness and more precise ABS control. On the front axle, single-piece racing aluminum brake calipers, combined with ventilated 390-millimeter knurled discs, ensure exceptional braking. Four-piston calipers and 370-millimeter discs are mounted on the rear axle.

To improve the performance in the pit stops, the 3 liter FT120 security tank can now be installed on the left or right side, to gain efficiency depending on how the circuit is designed. The doors and side windows can be removed.

The new competition bucket seats offer even greater protection to pilots in the event of a collision. These seats are now bolted on at six points. In combination with the adjustable pedals, they optimize the driver's center of gravity and provide greater safety in impacts. In addition, a piece located in the driver's door and made of carbon fiber, aluminum and Kevlar, with a plastic foam that absorbs energy, protects the pilot in a possible side impact.

For the first time, the 911 GT3 R has air conditioning. This ensures the ideal cooling of the interior and, thanks to the direct connection to the rider's seat and helmet, the rider keeps cool and this helps them focus and achieve constant performance during the race.

The new Porsche 911 GT3 R, which is priced at 459.000 euros plus tax and that will be delivered from December 2018. All data and specifications are provisional until it receives homologation from the FIA.
