2023 Porsche 911 GT3 Performance 
A naturally aspirated engine, what else?
With a full four liters of displacement and six cylinders. In a horizontally opposed layout. In the rear. Just as you would expect from a 911. Six individual throttle bodies ensure an even more direct engine responsiveness that is easier to control. With a high-revving concept that scratches the 9,000 mark. And with a maximum torque of 346 lb. ft. which has been increased by another 7 lb-ft compared with its predecessor. All this with a purebred sound that will blow you away in every direction.
6-speed GT sport manual transmission.
Optional in the 911 GT3 and standard in the 911 GT3 with Touring Package, it injects the pure and even more direct driving feeling back into the cockpit. With six performance oriented gears, extremely short shift throws and exceptionally precise, short gear changes. The focus is not on every tenth of a second, but on unconditional driving pleasure and unfiltered emotions. The manual gearbox also saves another 37 lb in weight.
Chassis.
For the first time in a 911 GT3, a double wishbone front suspension has been installed. The system is derived directly from the 911 RSR – and brings you valuable seconds ahead:
The responsiveness of the front axle has been significantly improved once again through this axle principle – and the associated lower friction in the shock absorbers. In addition, the new axle geometry allows for a set-up that provides greater cornering stability and even more immediate steering response. For even faster cornering speeds.
Rear-axle steering with sporty set-up.
At low speeds, the system steers the rear wheels in the opposite direction to that of the front wheels. This increases agility, especially when cornering. At high speeds, the system steers the rear wheels in the same direction as that of the front wheels. This increases driving stability, above all at high speeds or when overtaking on the race track.
2023 Porsche 911 GT3 Appearance 
Rear.
The rear of the new 911 GT3 is powerful. A powerful downforce is generated by the new wing attached to the top, as previously used on the 911 RSR. It is carried by two aluminum supports that are integral to the vehicle bodyshell. The so-called swan-neck connection ensures that there is a clean flow around the underside of the wing, leading to significantly less loss of downforce.
The completely new diffuser with large slats on the rear is aerodynamically efficient. It delivers up to four times more rear downforce than the rear diffuser of its predecessor.
Front.
A battle cry against the headwind: the front fascia of the new 911 GT3 models with their large openings. The incoming air cools the brakes, the coated air intake grilles protect against foreign objects. The air outlets in the central radiator are now integrated into the carbon fiber hood and emphasize the motorsport look.
Downforce. Balance. Cooling. Everything must be in harmony. The wide front spoiler lip ensures additional downforce on the front axle. Thanks to the new front diffuser, downforce on the front axle and vehicle balance can now be adjusted in stages. Together with the aerodynamically improved underbody panelling, downforce on the front axle and vehicle balance can be optimally coordinated. The air control elements behind the front wheels have been completely revised and now deliver twice the amount of downforce with the same air resistance.
Downforce.
When examining all measures taken to improve aerodynamics, the new 911 GT3 with fixed rear wing achieves approximately 60% more downforce than its predecessor. In the Performance position, which is not road-approved, it delivers more than twice as much downforce for use on the race track.
But before you start calculating now: get on the race track where you can experience the performance directly.
Wheels and tires.
For the first time, the 911 GT3 has staggered wheels sizes: with 20-inch wheels on the front axle and 21-inch wheels on the rear axle. Wide wheels mean a large contact patch and, therefore, high dynamic performance.
The wheels are silver-colored as standard and made of forged alloy. The black central locking device with ‘GT3’ logo is typical of motorsport – and highly functional. Tire sizes: 255/35 ZR 20 on 9.5 J x 20 at the front, 315/30 ZR 21 on 12 J x 21 at the rear. Road-legal Ultra High Performance tires ensure the necessary grip¹. Tire Pressure Monitoring System (TPMS), fitted as standard, features a racetrack mode which accounts for the lower pressure of cold tires before an outing on the circuit.
2023 Porsche 911 GT3 Comfort 
Sport Seats Plus.
The Sport Seats Plus with elevated side bolsters, electric seat height and backrest adjustment as well as the manual fore/aft adjustment are standard. The side bolsters are covered in leather, the seat centers in black Race-Tex, while the ‘GT3’ logo is embroidered on the headrests in Silver. The side bolsters on the cushion and backrest have a firm, sporty padding and offer excellent lateral support – even in the pelvis area. The backrest shell is finished in Dark Silver.
Adaptive Sport Seats Plus with 18-way electric adjustment of seat positions are available on request.
Porsche Connect.
Porsche Connect supports you with helpful services and the My Porsche app. You can synchronize destinations and calendars with your Porsche, plan trips with real-time traffic information and use music streaming services with your smartphone. Let your Porsche handle navigation, information and entertainment tasks. Using voice recognition, you can conveniently ask for information, such as the weather at your destination.
Everything you love about Porsche. But faster.
At the sporting limit, it is always about being direct. Especially on the racetrack but also with ergonomics in the cockpit. In this sense, the interior of the new 911 GT3 models is leading the way. It reflects on classic 911 virtues and extends them to new technological possibilities. The principle: analog fascination meets digital integration.
2023 Porsche 911 GT3 Safety & Warranty 
New Car Limited Warranty & Porsche 24-Hour Roadside Assistance Program for 4-Years / 50,000 Miles (whichever occurs first)
Porsche Active Suspension Management (PASM, –20mm).
This electronic adjustment of the shock absorber system actively and continuously adjusts the damping force on each wheel, based on current road conditions and driving style. PASM has two settings: ‘Normal’, which is a blend of performance and comfort, and ‘Sport’ where the set-up is much firmer.
Porsche Stability Management (PSM).
PSM is an automatic control system for helping to maintain stability at the limits of dynamic driving performance. The systems can be completely switched off in two stages. For intentionally sporty handling on the race track.
Porsche Torque Vectoring Plus (PTV Plus).
In conjunction with the 7-speed PDK, the system operates with an electronically regulated and fully variable rear differential lock with fully variable torque distribution. For increased traction and improved lateral dynamics, as well as enhanced stability when cornering under load change conditions and when changing lanes.
‘Smart’ lift system.
Available as an option, the lift system raises the 911 GT3 at the front axle by 1.1 in. To increase ground clearance at speeds of up to approximately 31 mph. A new feature is the automatic lift function which is based on personally stored position data.
