2023 Porsche 911 GT3 RS vs Old Porsche 911 GT3 RS
Comparison Visual Driving on Track with Exhaust Sound, Exterior & Interior Design

The 2023 Porsche 911 GT3 RS is uncompromisingly designed for maximum performance. The 518 hp 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.

The 4.0-liter high-revving naturally aspirated engine has been further optimized compared with the 911 GT3. The increase in power to 518 hp (911 GT3 – 502 hp) is achieved primarily via new camshafts with modified cam profiles. The seven-speed Porsche Doppelkupplung (PDK) has a shorter overall gear ratio than the 911 GT3 and is aided by air intakes on the underbody to ensure that the transmission can withstand even extreme loads during frequent use on track.

The 911 GT3 RS accelerates from 0 to 60 mph in 3.0 seconds (911 GT3 – 3.2 seconds) and reaches a top speed of 184 mph in seventh gear. Six-piston aluminum monobloc fixed-caliper brakes 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-caliper brakes. The optionally available Porsche Ceramic Composite Brakes (PCCB) use 410-mm discs on the front axle and 390-mm discs on the rear axle. The new 911 GT3 RS also comes standard with forged light-alloy center-locking wheels.
Street-legal Ultra High Performance tires measuring 275/35 R 20 at the front and 335/30 R21 at the rear provide a high level of mechanical grip.

Even the suspension is modified for improved aerodynamics. Because the wheel arches of the new 911 GT3 RS are subject to powerful airflows, the components of the double-wishbone front axle are designed with teardrop-shaped profiles. These aerodynamically efficient links increase downforce on the front axle at top track speed and are otherwise only used in high-end motorsport applications.
