Porsche It has unveiled the latest generation 911 GT3R, Porsche’s bet on the GT3 Series, and is based on the current 992nd generation, ready to race at the start of the 2023 season. Porsche aims to take advantage of greater performance reserves for the various Balance of Performance (BoP) ratings. . In addition, the goal was also to simplify the handling of the race car for the teams and reduce operating costs. The new 911 GT3 R comes after Porsche recently unveiled the limited-running 911 GT2 RS Club Sport 25 that is truly a collector’s item.
As for the 911 GT3R, it looks like Porsche has bumped it out of the park when it comes to making a thoroughbred race car that’s not only race ready, but looks like it’s going to win.
Porsche 911 GT3 R: Performance
Powering the vehicle is the semi-standard engine based on the 992nd generation 911 unit. Similar to the previous model, you get a water-cooled flat-six engine with four-valve technology and direct fuel injection. The main change is displacement: Like the 911 RSR, the new 911 GT3R’s engine capacity has increased by 5 percent from 4.0 liters to 4.2 liters. Porsche says this boosted the engine’s peak output to around 565 horsepower.
The high-speed six-cylinder engine runs without a turbocharger and sits in the rear of the vehicle, enhancing traction and braking. However, it has been tilted forward 5.5 degrees in order to create more headroom for the lower diffuser. Additional elements such as the alternator and air conditioning compressor have been moved just over 3 feet forward and down to a greater distance in front of the engine and gearbox, which has a positive effect on the 911 GT3R’s weight balance.
As for the transmission, the car gets a competition-netted six-speed sequential gearbox derived from the current 911 GT3 Cup where paddle shifts control the electronic shift cylinder actuator that results in quick and precise gear changes.
Porsche 911 GT3 R: Suspension and Brakes
Porsche claims the new suspension system allows for more precise steering and ensures less rear tire wear as well as less time spent on setup changes.
At the front axle, the car gets a double wishbone design. At the rear, the car gets a multi-link design. Porsche has improved KW shock absorbers to offer five tuning settings. Adjustments are made to the setup with what Porsche calls the gaskets. These shims are intended to enable precise adjustments without the time-consuming re-alignment of the suspension afterwards.
Porsche pushed the rear wheels back a bit, expanding the wheelbase from 96.8 inches to 98.7 inches. This doubles the load on the rear tires and improves tire performance consistency over longer periods.
In terms of braking hardware, the car comes with aluminum monobloc racing brake calipers which are now also supplied by specialist AP. The brakes are 15.3 inches in size, and are internally ventilated and 6-piston activated. At the rear are four-piston calipers and 14.5-inch discs. The company has included a software application for the fifth generation of its racing ABS system that also, you guessed it, reduces tire and brake wear. This is in addition to the new traction control system that also received further development.
Under the skin, the car gets an aluminum-and-steel composite based on the production model, albeit with significant modifications to use in the 911 GT3R.
A car like the new 911 GT3 R has been greatly improved in terms of aerodynamics. The highlight of the car is the height of the lower body at the front of the front axle, for the first time in conjunction with a smooth underbody and a rear diffuser. The magicians at Porsche discovered that this combination improved downforce without significantly increasing drag.
Porsche 911 GT3R: Safety
In terms of safety, Porsche says the new 911 GT3R comes with a seat closer to the center of the car. As in the previous version, the steering wheel and pedals can be adjusted longitudinally to suit the driver. The steering wheel design also received additional upgrades over the previous model. It includes elements that have proven themselves in the latest generation of the 911 GT3 and 911 RSR racing cars. The 10.3-inch screen, for example, comes from the successful one-man-made trophy rider, with a multi-key concept approved by Le Man’s class winner.
The Porsche 911 GT3 R shows what happens when a company decides to push the envelope of innovation and performance. The fact that it looks so good while doing it is just an added bonus for us to gear heads as it gives us another car to drool over.
