The new Porsche 911 GT3 RS makes no secret of its intentions: it is uncompromisingly designed for maximum performance. The 386 kW (525 PS) road-legal high-performance sports car takes full advantage of technology and concepts from motorsport. Even beyond the high-revving naturally aspirated engine with racing DNA and intelligent lightweight construction, it is, above all, the cooling and aerodynamic systems of the 911 GT3 RS that connect it most directly with its motorsport brother, the 911 GT3 R. #porsche #porschegt3rs #gt3rs #porsche992 #992gt3 #gt3

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 centre 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, total downforce is 860 kg.

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.

The look of the new 911 GT3 RS is characterised by the 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. Sideblades accurately direct air outwards. Front wheel arch ventilation is provided via louvred 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. Sideblades behind the intake ensure that the air is directed to the side of the vehicle.

High-revving four liter six-cylinder boxer engine

The 4.0-litre high-revving naturally aspirated engine has been further optimised compared with the 911 GT3. The increase in power to 386 kW (525 PS) is achieved primarily via new camshafts with modified cam profiles. The single-throttle intake system and the rigid valve drive are derived from motorsport. The seven-speed Porsche Doppelkupplung (PDK) has a shorter overall gear ratio than the 911 GT3. Air intakes on the underbody ensure that the transmission can withstand even extreme loads during frequent use on track. The 911 GT3 RS accelerates from zero to 100 km/h in 3.2 seconds and reaches a top speed of 296 km/h in seventh gear. Aluminium monobloc fixed-calliper brakes with six pistons each and brake discs with a diameter of 408 mm are used on the front axle. Compared with the 911 GT3, the piston diameters have been increased from 30 to 32 mm. In addition, the thickness of the discs has been increased from 34 to 36 mm. The rear axle continues to be fitted with 380-mm brake discs and four-piston fixed-calliper brakes. The optionally available Porsche Ceramic Composite Brake (PCCB) has 410-mm discs on the front axle and 390-mm discs on the rear axle. The new 911 GT3 RS comes standard with forged light-alloy centre-lock wheels. Road-legal sports tyres measuring 275/35 R 20 at the front and 335/30 R21 at the rear ensure a high level of mechanical grip.
