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 solid cam followers, which have also been optimised, are derived from motorsport. The seven-speed Porsche dual-clutch transmission (PDK) has a shorter overall gear ratio than the 911 GT3. 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.
Thanks to an array of lightweight construction measures, the lightest version of the 911 GT3 RS weighs in at just 1,450 kg (unladen weight according to DIN). The doors, front wings, roof, front lid and rear lid, for example, are made from carbon-fibre reinforced plastic (CFRP). Light CFRP is also used in the interior.
