The new Porsche 911 GT3 RS was built for one thing: Uncompromisingly designed for maximum performance. The 386 kW (524hp) road-legal high-performance sports car takes full advantage of technology and concepts from its motorsports heritage. Even beyond the high-revving naturally aspirated engine with racing DNA and intelligent lightweight construction, it inherits — above all — its cooling and aerodynamic systems from its motorsport brother, the 911 GT3 R.

The basis for a significant performance boost is the concept of a central radiator — an idea that was first used in the Le Mans class-winning 911 RSR and subsequently in the 911 GT3 R. Instead of the three-radiator layout seen in previous cars, the new 911 GT3 RS relies on a large, angled center radiator in the car's nose, positioned where the luggage compartment is located on other 911 models.
This has made it possible to use the space freed up on the sides to integrate active aerodynamic elements. Continuously adjustable wing elements in the front and on the two-part rear wing, in combination with a number of other aerodynamic measures, provide 409 kg of total downforce at 200 km/h. This means that the new 911 GT3 RS generates twice as much downforce as its 991.2-generation predecessor and three times as much as a current 911 GT3. At 285 km/h, the total downforce is 860 kg.

Moreover, a drag reduction system (DRS) is fitted in a production Porsche for the first time. To achieve low drag and higher speeds on straight sections of the track, the DRS allows the wings to be flattened out at the push of a button, within a specific operating range. The airbrake function is activated during emergency braking at high speeds: The wing elements at the front and rear are set to maximum, creating an aerodynamic deceleration effect that significantly supports the wheel brakes.

Exterior-wise, it is characterized by a large number of functional aerodynamic elements. The most prominent feature of the GT sports car is the swan-neck-supported rear wing, which is significantly larger in all dimensions. The rear wing consists of a fixed main wing and an upper, hydraulically adjustable wing element. For the first time on a Porsche production vehicle, the upper edge of the rear wing is higher than the car's roof. In addition, the front end of the 911 GT3 RS no longer has a front spoiler, but instead features a front splitter that divides the air flowing over and underneath. Side blades accurately direct air outwards. Front-wheel arch ventilation is provided via louvered openings in the front wings. Inlets behind the front wheels, in the style of the iconic Le Mans-winning 911 GT1, reduce the dynamic pressure in the wheel arches. Side blades behind the intake ensure that the air is directed to the side of the vehicle. Air from the centrally positioned radiator flows out via large nostrils on the front lid. Fins on the roof direct the air outwards, ensuring cooler intake temperatures in the rear.
