Porsche officially unveils its 911 GT3 R type 992

If you are an avid reader of Endurance-Info, you already know almost everything about the new 911 GT3 R. And for good reason, we had the chance to attend a private test session of the beast, on the Spa-Francorchamps circuit. But on the sidelines of the edition of the 24 Hours of Spa – flagship round of the GT World Challenge Endurance Cup – the German manufacturer said more about its new weapon, a few hours after the sworn enemy Ferrari unveiled the little sister of the 488 GT3 (see HERE).

The new GT3 R is based on the 992 and more precisely on the 911 GT3 and not the 911 GT3 RS, unlike its predecessor. And this in particular for reasons of timing, the GT3 RS type 992 having simply not yet been unveiled.

As surprising as it may seem, the development of the GT3 R began in 2019. The priority was to improve the handling, both for professional drivers and gentlemen drivers, while taking into account the BoP and the classification of pilots. According to Porsche, this has not prevented a drop in operating costs. For sale, the price of the new GT3 R is 511,000 euros excluding taxes and options.

The new 911 GT3 R has a complex mission, acknowledges Michael Dreiser, Sales Manager at Porsche Motorsport. His ancestor has won almost everything there is to win on the GT3 scene in four seasons since 2019. Landmark successes that include overall victories at the 24 Hours at the Nürburgring and also here at Spa-Francorchamps. Run by our customers, the predecessor took class wins at the 24 Hours of Daytona and 12 Hours of Sebring. The new model has to cope with a considerable workload in the hands of Porsche customer racing teams. »

As on the previous model, the engine is a water-cooled flat 6 with four valves and direct fuel injection. But it is in its displacement that lies its major novelty. This has increased by 5%, from 3,997 to 4,194 cm3. The power, meanwhile, has been increased to around 416 kW (565 horsepower). But the most important thing is certainly the optimization of the torque and power curve over the entire rev range.

An engine that has been tilted 5.5° forward, allowing better distribution of the masses and the diffuser to gain in efficiency, thanks to an increased surface and height. The alternator and the air conditioning compressor have been moved a good meter forward and down, which also has a positive effect on the balance of the car.

The six-speed sequential gearbox is derived from the current 911 GT3 Cup. The suspension – of which many details have been modified – promotes traction, allows more precise steering, ensures less wear on the rear tires and reduces the time spent changing settings.

For this, many components and technical solutions have been borrowed from the 911 RSR. At the front axle, the wheels are controlled by a state-of-the-art double wishbone system. The rear axle is of the multi-link type. The KW shock absorbers have been improved and offer five adjustment possibilities. Tuning changes are made using so-called shims. These plates allow precise adjustments without the need to realign the suspension afterwards, which takes a lot of time. The rear wheels have been moved a bit further back, increasing the wheelbase from 2,459 to 2,507 millimeters. It also reduces the load on the rear tires and improves the consistency of tire performance over long stints.

In addition to the aluminum monobloc racing brake calipers, the brake discs of the new 911 GT3 R are now supplied by AP. The steel, internally ventilated and slotted front discs measure 390mm in diameter and are powered by six pistons. At the rear, four-piston calipers and 370 mm diameter discs are fitted.

The kinematics of the suspension have been revised, with the aim of ensuring better traction, more precise steering, less damage to the rear tyres. Here again, for the sake of saving time in particular… Pedal set and bucket seat are adjustable.
