Porsche 911 GT3 R Model Year 2026 vs. Previous Generation – Detailed Comparison

Key Differences: 2026 Evolution vs. Previous Generation GT3 R

2026 Evolution:
- Added ventilation louvres on the top of front wheel arches, improving airflow and counteracting front-end dive during braking—resulting in better aerodynamic balance and more precise braking.
- Rear enhancements: 4 mm Gurney flap on the swan-neck rear wing for extra downforce and broader balance adjustments. Underbody is fully enclosed and reinforced. Modified multi-link rear-axle kinematics improve anti-squat under acceleration.
Previous GT3 R (992.1):
- Baseline aerodynamic package carried over from earlier developments, but without these latest refinements.

2026 Evolution:
- Optimised double-wishbone front suspension with better kinematics to provide anti-dive resistance under braking.
- Upgraded Bosch ABS (5th generation) for better dynamic braking control.
- Enhanced electro-hydraulic power steering featuring improved fluid cooling to ensure consistent steering effort during long, demanding races.
- Ceramic rear wheel bearings, and NACA-duct-cooled drive-shaft centering pins, plus refined rear brake cooling—boosting durability, especially on high-speed, low-ride-height circuits.
Previous GT3 R (992.1):
- Reliable baseline setup, but lacking these thermal and mechanical enhancements.

Both Generations:
- Use a naturally-aspirated 4.2 L water-cooled flat-six engine, offering up to 416 kW (565 PS) depending on Balance of Performance (BoP).
- Transmission: 6-speed sequential dog-type gearbox.

Porsche offers update kits for existing 992-generation GT3 R cars, priced from around €41,500 (plus VAT), allowing teams to retrofit many of the evolution components.
The 2026 evolution is also being sold new to customer teams at approximately €573,000 (excl. VAT and options).

For the 2026 Evolution, additional optional packages are available:
- Sensor package (e.g., laser ride-height sensors)
- Endurance package
- Pit-lane link package
- Camera package (including water-bottle system mounts, rear-view camera, etc.)
