The new 911 GT3 RS will accelerate from 0 to 60 mph (96.5 km/h) in 3.0 seconds, which is 0.1 seconds quicker than the previous 911 GT3 RS and 0.2 seconds quicker than the current 911 GT3 with PDK. Top speed is 193 mph (310 km/h).
The 4.0 liter naturally aspirated flat-six engine delivers 20 hp more than the engine in the 2016 911 GT3 RS and the current 911 GT3. Plasma coated cylinder liners, a central oil supply through the crankshaft with larger bearing diameters, larger connecting rod bearings and the rigid valve train with shims to provide valve clearance compensation all carry over from the 2018 911 GT3. Capable of up to 9,000 rpm like the regular 911 GT3, the engine takes in ram air through openings in the rear quarter panels, and it is closely related to the unit used in current Porsche 911 race cars. The muffler and exhaust tips are made of titanium. The engine is mated to a specifically tuned 7-speed PDK which features performance-oriented gearing with the top track speed being reached in 7th gear, like all GT tuned PDK transmissions.
Lightweight forged wheels are 9.5 x 20 inches up front, with newly developed 265/35 ultra-high performance (UHP) tires and 12.5 x 21 inch wheels with 325/30 UHP tires in the rear. The wider tires offer a significantly larger contact patch than those of the regular 911 GT3. Large cross-drilled grey cast iron rotors measuring 380 mm front and rear are standard, while the Porsche Ceramic Composite Brake system with 410 mm rotors at the front and 390 mm rotors at the rear can be ordered as an option. The ceramic rotors are 50 percent lighter than cast iron rotors.
