Aerodynamics play a key role in the GT4 RS’s performance, particularly for stability and downforce.
The fixed rear wing with swan neck suspension, inspired by the Porsche 911 RSR and GT3, generates additional downforce, ensuring the car sticks firmly to the road surface at high speeds. NACA air intakes on the front bonnet improve airflow for cooling while reducing drag. Air intakes behind the side windows feed the engine with additional air and also create a sensational sound in the cabin, and a diffuser and front splitter specially developed to minimise turbulence and ensure optimum airflow under the car complete the picture.
The interior exudes pure racing ambition: minimalist and focused on the driver, with details such as the Alcantara upholstery and carbon bucket seats.
The GT4 RS is therefore not just a fast car, but an extraordinary machine for enthusiasts who really want to experience driving.
