Porsche Unveils New Naturally Aspirated 911 GT3 R Race Automobile That is Extra Centered On Usability Than Velocity
Porsche North America has as we speak unveiled its newest technology of GT race automobile, the 911 GT3 R. With a much bigger engine, higher aerodynamic efficiency, and optimized car stability, the brand new automobile is meant to be the model’s most useable 911 race automobile to this point.
The automobile will compete within the GT3 class, which is the highest GT class in North America with the IMSA WeatherTech SportCar Championship and in Europe with the FIA World Endurance Championship. That signifies that the automobile will probably be eligible to participate in the 24 Hours of Le Mans for the primary time, and that has had an vital position in defining the design remit of the automobile.
“Drivability is remarkably vital to the wide selection of drivers that we now have competing right here and that was a spotlight of the sort 992 911 GT3 R,” mentioned Volker Holzmeyer, CEO of Porsche Motorsport North America. “We’ve got already had overwhelming curiosity within the automobile, and we’re trying ahead to seeing it flip its first wheel right here quickly.”

On the middle of the automobile’s efficiency is, in fact, the naturally-aspirated flat-six engine. Primarily based on the 992 911‘s engine, the primary enchancment is in displacement, which elevated 5 %, from 3,997 cc to 4,194 cc. The additional measurement offers it a most output of 558 hp (416 kW/565 PS). The primary motive for the expansion, although, was to make the ability and torque bands extra useable to go well with a wider vary of drivers at completely different expertise ranges.
The engine is positioned, as you’d count on, within the rear of the 911 GT3 R, but it surely has been tilted ahead by 5.5 levels to create more room for the rear diffuser. Auxiliary elements have been moved ahead and down into the area in entrance of the engine, which has had a optimistic impact on weight stability.
Shifting is dealt with by a sequential six-speed contest-mesh gearbox that was derived from the 911 GT3 Cup race automobile. Drivers choose gears with paddles behind the steering that management an digital shift drum actuator for fast and exact gear adjustments.
The suspension was additionally modified, beginning on the entrance with state-of-the-art double wishbones and on the again with a multi-link design. The shock absorbers come from KW and are designed to be simply adjustable. Set-up modifications could be executed with shims that don’t require time-consuming re-alignment of the suspension after each adjustment. All of which has been executed within the title of creating the race car simpler to make use of.
The positioning of the central pivot factors on the entrance axle, in the meantime, permits for more room for the aerodynamic idea. As with the 911 RSR, the 911 GT3 R has an elevated underbody that enables extra clear air to hit the diffuser and reduces the pitch sensitivity of the automobile and permits for extra downforce with out including any drag. The wheelbase, in the meantime, has been prolonged to scale back the masses on the rear tires and enhance their consistency over lengthy racing stints.
Aluminum monobloc brake calipers and discs are supplied by AP. The 390 mm entrance discs are slotted and fabricated from metal and clamped by six-piston calipers. The rears, in the meantime, are 370 mm throughout and get four-piston calipers. Nearly the entire physique panels are fabricated from carbon fiber to maintain weight down, whereas the wheel arches are fabricated from aramid fibers.
Just like the auxiliary elements, the driving force has additionally moved nearer to the center of the 911 GT3 R. That allowed Porsche so as to add an ergonomic seat and an improved roll cage for the newly developed FIA facet affect mandates. The cockpit has options first proved in different types of motorsport, like the 911 GT3 Cup automobile’s 10.3-inch show and a multi-switch idea.
“Our job was much less about making the brand new 911 GT3 R even quicker – the classification inside efficiency home windows set by the BoP shortly cancels out this benefit,” mentioned Sebastian Golz, the 911 GT3 R’s mission supervisor. “For us, it was primarily about our prospects having the ability to drive the racing car quick for longer. This requires sturdiness and that’s why we targeted predominantly on improved drivability.”
Porsche says it additionally labored to make working the automobile cheaper for racing groups. It will likely be prepared for the 2023 racing season and North American buyer groups will be capable of purchase the automobile by means of Porsche Motorsports North America at a worth of $567,210.
