The chassis of the new 911 GT3 benefits from Porsche's motorsport experience and has been re-tuned for even better driving dynamics. The two-seater sits around 25 millimetres lower than the 911 Carrera S. In addition to the further refined basic design, the chassis also boasts superior handling characteristics, thanks predominantly to the active rear-axle steering. Depending on the speed, the rear wheels turn either opposite to the front wheels or in the same direction, which improves agility and stability. Other features that improve the car's driving dynamics include the dynamic engine mounts and the rear differential lock (Porsche Torque Vectoring, PTV/PTV+). When it comes to its appearance, the Porsche 911 GT3 leaves little doubt as to its purpose. The dominant carbon rear wing emphasises the fact that the sports car's form is determined by aerodynamics. The lightweight front end and front spoiler have been designed for a better air flow. The aerodynamic enhancement is also evident on the lightweight rear end with exhaust air openings and on the new diffusor.
High-speed racing engine producing 368 kW (500 hp) At the heart of the new 911 GT3 beats a thoroughbred motor racing engine. The main development aims for the high-speed engine were performance and stability for heavy use on racing circuits. The naturally aspirated six-cylinder flat engine with four-litre displacement generates extremely dynamic power in the 911 RSR, as well as the 911 GT3 R and 911 GT3 Cup. The machine is the most powerful naturally aspirated direct-injection engine and has the greatest displacement that Porsche has ever produced for a six-cylinder flat engine on the road. It produces 368 kW (500 hp) of power and 460 Nm of torque. This represents an increase of 25 hp and 20 Nm when compared to the previous model with 3.8-litre displacement. The power curve peaks at 8,250 rpm, while maximum torque is achieved at 6,000 rpm.
New GT sports manual transmission with six gears A shorter shift lever, short shift paths, precise shift stops and six optimally-tuned gears: For the purists among the 911 GT3 drivers, Porsche has developed the new GT sports manual transmission with dual-mass flywheel. The transmission ratio of the six gears is precisely tuned to the power development of the engine and offers particularly sporty shifting characteristics. The automatic intermediate acceleration function ensures sporty gear changes when downshifting. It is activated via the SPORT button on the centre console, delivering highly dynamic shift operations from faster synchronisation of the gear wheels - ensuring an even more emotional driving experience on winding roads. Unlike the PDK transmission, the manual transmission model transfers the power to a mechanically-controlled rather than electronically-controlled rear-differential lock (PTV) with locking values of 30/37 per cent (traction/overrun). Another advantage: The combination of manual transmission and mechanically-controlled differential lock weighs around 15 kg less than the PDK variant. This reduces the empty weight to 1,413 kg, thus increasing the weight-to-power ratio to 3.84 kg/kW (2.83 kg/hp). The high-performance 911 therefore sprints from zero to 100 km/h in just 3.9 seconds.
Porsche Track Precision app as standard In addition to Porsche Communication Management (PCM) including an online navigation module with real-time traffic information, the standard equipment also includes the Connect Plus module and the Porsche Track Precision app. The app enables Porsche 911 GT3 drivers to display, record and analyse detailed driving data on their smartphone. Lap times can be timed either automatically via a precise 10-Hz GPS signal in the PCM or manually using the operating lever of the optional Chrono Package, and compared on a smartphone. The app displays the driving dynamics on the smartphone in race track situations. In addition to sector and lap times, deviations from the set reference lap are also displayed. Graphical analyses of the driving data and a video analysis help the driver to improve driving performance. Recordings, lap profiles and driver profiles can be managed and shared directly via a smartphone. Without the Chrono Package, precise lap times can be sent to the app using the laptrigger available from Porsche Tequipment. This can be positioned next to the start/finish line to automatically time lap times and send the data to the PCM and smartphone app.
