The Porsche 911 GT3 R has been revealed, ahead of its competitive debut in the GT3 racing category next year.
Based on the latest generation of Porsche’s ‘992’, the new 911 GT3 R will see action with customer teams in the GT3 categories from next year, as part of the North American IMSA series and the World Championship of Resistance of the FIA.
The 911 GT3 R is a larger 4.2 liter (4194 cc) version of the naturally aspirated flat-six engine in the road-going 911 GT3, now developing 412 kW, with a redline of 9250 rpm, 37 kW more and 250 rpm more than the road car. the runner is based.
Porsche says the engine has been tuned for an “optimized power and torque curve across the entire rev range,” said to make it “better suited to gentleman drivers” without an extensive racing background.
Mated to a six-speed sequential gearbox with paddle shifters, the 4.2-litre engine has been rotated 5.5 degrees forward to allow for a larger rear diffuser, and the alternator and air compressor conditioned they moved one meter forward for better weight distribution.
The car measures 4,619mm in length and 2,039-2,050mm in width, with a base weight of 1,250kg, subject to ‘performance balance’ rules, which can increase or decrease the car’s weight to ensure that all GT3 cars of different shapes and sizes match in terms of performance. .
Under the skin, double-wishbone front suspension and multi-link rear suspension, with five-way adjustable shock absorbers, adjustable sway bars and forged aluminum control arms, plus a mechanical limited-slip rear differential.
The arches fill 18-inch center-lock wheels with Michelin competition tires, which hide 390 mm front and 370 mm rear steel brakes with aluminum six-piston front and four-piston rear calipers, and a brake system anti-lock braking system (ABS) designed by Bosch of Germany.
The 911 GT3 R’s aerodynamics package is even more extreme than the road car it’s based on, with more aggressive bumpers and skirts, wider wheel arches, additional vents for greater cooling and a larger rear spoiler tall similar to the upcoming road-going GT3 RS. .
The GT3 R’s wheelbase is 48mm longer than the road-going GT3 (2507mm vs 2459mm) to “reduce load on the rear tires and improve the consistency of tire performance over longer stays”, while a Revised front axle geometry allows for more efficient underbody aerodynamics.
The body is made from an “intelligent steel-aluminum composite”, covered in carbon fiber for the front and rear decks, doors, side panels, rear wing and “gooseneck” roof ” and aramid fibers for the wheel arches.
Inside, there’s a ventilated carbon fiber competition seat with six-point harnesses, adjustable steering and pedal assemblies, heated windshield, a carbon fiber steering wheel, 10.3-inch digital control screen, two safety nets and a fire extinguisher.
The Porsche 911 GT3 R will make its racing debut next year. It is available for customer teams to order from €511,000 (AU$755,000) before tax.
