The 992-generation Porsche 911 GT3 RS is the most track-focused road-legal variant in the current 911 lineup. Porsche developed it as a direct transfer of the GT3 R racing programme to a road-registered car, carrying over aerodynamic structures, suspension geometry and powertrain calibration from competition. The Weissach Package extends this further, removing close to 15 kilograms through carbon fibre components and magnesium wheels.
Four elements define the car: a high-revving naturally aspirated engine, an aerodynamic package derived from motorsport, a chassis calibrated for circuit use, and a construction approach centred on reducing mass at every opportunity.
EXTERIOR
Aerodynamic systems
The bodywork of the GT3 RS is shaped by aerodynamic function rather than styling. The two-part active rear wing generates 860 kilograms of downforce at 285 km/h, double the figure of the 991.2-generation car. It incorporates an F1-inspired drag reduction system, activated via a steering wheel button on straight sections of the track to flatten the wing elements, reducing drag and increasing straight-line speed. Under hard braking at high speeds, the wings move to maximum angle automatically, creating an aerodynamic deceleration effect that supplements the mechanical brakes.
At the front, continuously adjustable wing elements work alongside fixed side blades to control downforce balance. The front suspension links use a teardrop cross-section that generates additional downforce at speed, a detail introduced from the GT3 R. Front fender louvres release wheel arch pressure to stabilise the front axle, and underbody fins direct airflow rearward. A single central radiator replaces the conventional three-radiator setup, occupying the space normally used for a front luggage compartment.
Lightweight exterior construction
Doors, front wings, roof and bonnet are produced in carbon fibre reinforced plastic. With the Weissach Package, exposed carbon fibre is applied to the roof, bonnet, upper mirror housings and sections of the rear wing. Carbon fibre anti-roll bars and coupling rods are fitted at both axles. The standard forged aluminium centre-lock wheels are replaced by 20-inch and 21-inch forged magnesium wheels developed with BBS. This reduces rotational and unsprung mass, sharpening braking response and steering feel.
INTERIOR
Driver-focused cabin
Weight reduction runs through every element of the interior. Carbon fibre bucket seats provide firm lateral support with minimal mass. Door panels are finished in carbon fibre, and fabric straps replace conventional door pulls. The dashboard top is finished in Race-Tex to eliminate glare, a detail adopted from Porsche’s competition cars.
The Weissach Package adds a rear roll cage with a carbon-weave satin finish, reinforcing the structure while keeping additional weight low. Steering wheel paddles are machined from magnesium and use magnetic haptic elements from the 911 GT3 Cup car. The Weissach emblem appears on the passenger-side dashboard trim and on the seat headrests.
Controls Interface
Four rotary controls on the steering wheel provide direct access to suspension settings, traction control, differential response and stability systems without navigating through menus. Normal, Sport and Track modes are available, with Track mode allowing each system to be adjusted independently.
PERFORMANCE
4.0-litre naturally aspirated flat-six
The GT3 RS uses a 4.0-litre naturally aspirated flat-six producing 525 CV at 8,500 rpm and 465 Nm of torque at 6,300 rpm. The engine builds on Porsche’s motorsport experience, incorporating an individual throttle intake system and optimised valve train for sustained performance under high loads. Throttle response remains immediate across the rev range, with power delivered in a linear and predictable way.
Seven-speed PDK
The seven-speed PDK dual-clutch gearbox features a shorter overall gear ratio than the 911 GT3, improving acceleration and in-gear response on track. In manual mode, shifts are controlled via steering wheel paddles. Underbody air intakes provide additional cooling to maintain gearbox performance during extended track use.
Engineering and Driving Dynamics
Suspension and torque vectoring
The double wishbone front suspension introduced on the 992 GT3 carries over to the RS with revised geometry. The front track is 29 millimetres wider, and the lower ball joint is positioned further down to reduce pitch under braking. At the rear, a multi-link setup with adjusted spring rates works alongside the increased aerodynamic load.
Porsche Active Suspension Management (PASM) allows the damping to be fine-tuned, with separate control over rebound and compression, especially in Track mode. Rear-axle steering sharpens the response at lower speeds and adds stability as pace increases.
Torque distribution relies on Porsche Torque Vectoring Plus, which uses an electronically controlled rear differential. The lock characteristics are adjusted directly from the steering wheel, making it possible to adapt the car’s balance as grip levels change. Traction and stability control can also be reduced step by step or switched off entirely.
Braking and road usability
Standard steel brakes use aluminium fixed callipers with 408-millimetre front discs. The optional Porsche Ceramic Composite Brake system increases disc size to 410 millimetres at the front and 390 millimetres at the rear.
A front axle lift system raises the nose by around 30 millimetres at low speeds, helping to protect the aerodynamic underbody on public roads, and lowers automatically once speed increases.
MARKET COMPARISON
GT3 RS vs Porsche 911 S/T
The 911 S/T uses the same 4.0-litre naturally aspirated flat-six producing 525 CV, but pairs it with a six-speed GT Sport manual transmission. At 1,380 kilograms, it is 102 kilograms lighter than the GT3 RS, a difference achieved through extensive carbon fibre construction and the deletion of rear-axle steering. The GT3 RS is built for circuit work. The S/T is built around the experience of driving on open roads.
GT3 RS vs Ferrari 296 GTB
The Ferrari 296 GTB combines a 3.0-litre twin-turbocharged V6 with an electric motor, producing a total of 830 CV. Its hybrid powertrain focuses on maximum performance while offering a broader operating range in everyday driving. The GT3 RS follows a different direction. Its performance comes from aerodynamic load and chassis precision, supported by a naturally aspirated engine and a track-focused setup.
GT3 RS vs Lamborghini Huracán STO
The Huracán STO is derived from Lamborghini’s Super Trofeo and GT3 racing programmes and is powered by a 5.2-litre naturally aspirated V10 producing 640 CV. Its aerodynamic package includes a manually adjustable rear wing, contributing to a total downforce of 420 kilograms at 280 km/h. Both cars rely on naturally aspirated engines and aerodynamic development to achieve circuit performance. The GT3 RS generates significantly more downforce, with engineering derived directly from Porsche’s GT3 race cars.
GT3 RS vs McLaren 765LT
The McLaren 765LT uses a 4.0-litre twin-turbocharged V8 producing 765 CV, combined with a dry weight of 1,229 kilograms achieved through extensive use of carbon fibre. Its approach to circuit performance centres on power-to-weight ratio and mechanical grip.
The GT3 RS takes a different path. It carries more weight, yet finds its pace through aerodynamic load and chassis stability at higher speeds.
Final Words
The 992 GT3 RS with the Weissach Package represents the most focused road-legal 911 currently available. Its 4.0-litre flat-six, DRS-equipped aerodynamics and lightweight construction drawn from Porsche’s racing programmes work together as a cohesive system.
The Weissach Package builds on that foundation with targeted weight reduction and material changes, without altering the car’s core character. Built for drivers seeking the closest link to Porsche’s race car engineering, a connection best experienced on a circuit.
