Atlanta, Aug. 17, 2022 (GLOBE NEWSWIRE) — The 2023 Porsche 911 GT3 RS is clear in its intentions: it is designed without compromise for maximum performance. The road-legal 518hp high-performance sports car takes full advantage of motorsport technology and concepts. Even beyond the high-revving naturally aspirated engine with racing DNA and intelligent lightweight construction, it is above all the 911 GT3 RS’s cooling and aerodynamic systems that tie it most directly to its sister of motorsport, the 911 GT3 R.
Motorsport-inspired central radiator – the basis for active aerodynamics
The basis for a significant performance boost is the concept of a central radiator – an idea that was first used in the Le Mans-winning 911 RSR and then in the 911 GT3 R. Instead of the three-radiator arrangement from previous cars, the new 911 GT3 RS relies on a large, angled central radiator in the nose of the car, positioned where the luggage compartment is on other 911 models. on the sides to integrate active aerodynamic elements. Infinitely adjustable wing elements at the front and on the two-piece rear wing, in combination with a number of other aerodynamic measures, deliver over 900 lbs. downforce to around 124 mph, twice that of the 991.2 generation predecessor and three times that of a current 911 GT3. At 177 mph, total downforce is 1,895 lbs, equivalent to a Porsche 356 A.
A drag reduction system (DRS) is fitted to a production Porsche for the first time. To achieve low drag and higher speeds on straight sections of the track, DRS allows the wings to be flattened at the press of a button, within a specific operating range. During hard braking at high speeds, the airbrake function positions the wing elements front and rear to support deceleration by maximizing aerodynamic drag.
The determined look of the new 911 GT3 RS is characterized by the large number of functional aerodynamic elements. The most prominent feature of the GT sports car is the gooseneck-supported rear spoiler, which is significantly larger in all dimensions than the spoiler of its predecessor. The rear wing consists of a fixed main wing and a hydraulically adjustable upper blade. For the first time in a production Porsche vehicle, the upper edge of the rear fender is higher than the roof. A front splitter divides air flowing above and below in parallel with side blades on the front fascia that deflect air outward. Front wheel arch ventilation is provided by distinctive louvered openings in the front quarter panels. Air intakes behind the front wheels inspired by the iconic Le Mans-winning 911 GT1 reduce dynamic pressure in the wheel arches. Air from the central radiator flows through large nostrils on the front bonnet. Further back, fins on the roof direct air outward, ensuring cooler intake temperatures at the rear. In the new 911 GT3 RS, the openings in the rear side panel serve exclusively to improve aerodynamics and not to draw in combustion air. The rear wheel arch also features an air intake and a side blade for optimized airflow. The rear diffuser is a modified version of the one fitted to the 911 GT3.
Track suspension adjustable from inside the car
Even the suspension is modified for better aerodynamics. Because the wheel arches of the new 911 GT3 RS are subjected to powerful airflows, the components of the double wishbone front axle are designed with teardrop profiles. These aerodynamically efficient links increase downforce on the front axle by approximately 88 lbs. at maximum speed on the track and are otherwise only used in high-end motorsport applications. Front track width increases by 1.14 inches (29 millimeters), requiring longer double-wishbone front axle links.
To ensure that the balance of downforce between the front and rear axles is maintained even when braking at high speeds, the suspension engineers have significantly reduced pitching under braking. On the new 911 GT3 RS, the front ball joint of the lower swinging arm has been placed lower on the front axle. The multi-link rear axle was also adjusted, with changed spring rates. The driver assistance systems and the rear axle steering also have an even more dynamic setup here.
The 911 GT3 RS offers three driving modes: Normal, Sport and Track. In Track mode, the basic settings can be adjusted individually. Among other parameters, the rebound and compression damping of the front and rear axles can be adjusted separately and in several stages. The rear differential can also be adjusted via rotary controls on the steering wheel. This is done quickly and intuitively with an operating and display concept also borrowed from endurance racing. Four individual rotary controls and a button for the drag reduction system (DRS) are located on the steering wheel. These rotary controls appear in the instrument cluster during the tuning process. The 911 GT3 RS also features the already familiar 911 GT3 track display. With the press of a button, the driver can reduce the two seven-inch side screens to only essential information. The shift indicators on the left and right of the analogue tachometer were also carried over from the 911 GT3.
High-revving four-litre six-cylinder boxer engine
The naturally aspirated 4.0-liter high-revving engine has been further optimized compared to the 911 GT3. The power increase to 518 hp (911 GT3 – 502 hp) is achieved mainly via new camshafts with modified cam profiles. The single-throttle intake system and stiff valve train are motorsport-derived. Like the 911 GT3, this engine also has six individual throttle bodies; one per cylinder. The seven-speed Porsche Doppelkupplung (PDK) has a shorter overall gear ratio than the 911 GT3 and is aided by air intakes on the underbody to ensure the transmission can handle even extreme loads in frequent use on track.
The 911 GT3 RS accelerates from 0 to 100 km/h in 3.0 seconds (911 GT3 – 3.2 seconds) and reaches a top speed of 290 km/h in seventh gear. Six-piston aluminum monoblock fixed-caliper brakes and brake discs with a diameter of 408 mm are used on the front axle. Compared to the 911 GT3, the piston diameters have been increased from 30 to 32 mm. In addition, the thickness of the discs has been increased from 34 to 36 mm. The rear axle continues to feature 380mm brake discs and four-piston fixed-caliper brakes. The optional Porsche Ceramic Composite Brakes (PCCB) brakes use 410 mm discs on the front axle and 390 mm discs on the rear axle. The new 911 GT3 RS is also fitted as standard with forged light-alloy wheels with central locking. Road-legal Ultra High Performance tires measuring 275/35 R 20 at the front and 335/30 R21 at the rear provide a high level of mechanical grip.
Lightweight construction all the way
Intelligent lightweight construction has been a basic principle of all RS models since the legendary 911 Carrera RS 2.7. Thanks to a series of lightweight construction measures such as the extensive use of carbon fiber reinforced plastic (CFRP), the 911 GT3 RS weighs just 3,268 pounds. The doors, front quarter panels, roof and bonnet, for example, are made of CFRP. Lightweight CFRP is also used on the interior, including standard full bucket seats, trimmed in black leather and Race-Tex joining carbon fiber trim throughout the interior to characterize the pure, sporty ambience.
Available with the Weissach pack
The Weissach package, available at an additional cost, includes a considerable number of modifications compared to the standard vehicle. The hood, roof, parts of the rear fender and the upper part of the side mirror housings are made of visible carbon fiber. The front and rear anti-roll bars, the rear tie rods and the shear panel on the rear axle are made of CFRP and contribute to a further improvement in driving dynamics. Another highlight of the Weissach package are the PDK shift paddles with motorsport-derived magnetic technology. This makes gear changes particularly precise thanks to a pressure point and a clearly perceptible click. Magnesium forged wheels are included in the Weissach package and save 17.6 lbs. less weight without spring compared to standard wheels.
The 2023 911 GT3 RS is expected to arrive in U.S. dealerships by Spring 2023. Starting MSRP is $223,800, excluding $1,450 for processing, delivery and handling.
Exclusive Porsche Design Chronograph
Inspired by the mindset of motorsport, where maximum precision is paramount, Porsche’s watch factory in Solothurn, Switzerland, developed the 911 GT3 RS chronograph. This mechanical watch is available as an option, and is reserved for car owners. It rests on a bead-blasted case, in natural or black titanium, and equipped with a screw-down crown. Inside the watch is the Porsche Design WERK 01.200 mechanical chronograph caliber, COSC-certified for its high precision. Its flyback function allows the wearer to start, stop and reset the second hand in a single gesture. The chronograph pushers, which feature “Start/Stop” and “Next Lap” laser engravings, reveal that this chronograph is more than just telling the time. In addition to innovations, such as the pulsometer scale on the bezel, there are also many design features and materials from the GT3 RS.
