Porsche 911 GT3



Porsche has launched a new generation of  GT3 of the 992-series 911 GT3. The new model is described as “a highly athletic road car fit for high-performance driving on track balanced with the demands of everyday use”.
This time Porsche Motorsport have put all their effort to get the most out of their racing technology into a production model that can be used as a daily driver.
Highlights:
  • Double wishbones used for front suspension for the first time
  • 2021 911 GT3’s engine, aero and tech upgrades help set a sub-7min Nürburgring time
  • 6-speed manual and 7-speed dual-clutch auto gearboxes available

Design and Aerodynamics



For more aerodynamics and cooling, the new GT3 get's a lot of impressive exterior design also with increase in width than its predecessor.
The most significant addition is a new ‘swan neck’ rear wing, adopted from that of the 911 RSR racing car with a prominent diffuser that can also be adjusted into a ‘Performance’ position to increase downforce. Porsche claims this mode is reserved “strictly for outings on the circuit”.
Other visible changes over a standard 992-gen 911 include a deeper front bumper with cleaner sides for further improved aero and a large central intake, plus further airflow-enhancing ‘nostril’ vents on the front bonnet. One GT3-specific optional extra is a roof made of exposed carbonfibre.

Interior



Interior is somewhat similar at the front but to with kerb weight-reducing measures such as the traditional removal of the rear seats and reduced sound proofing. However, they didn't remove the air conditioning to reduce weight further. 
With more use of Alcantara trim, sports seats and a half roll cage, there is one significant change over the standard 992 models: the gear selector. Rather than the shift-by-wire toggle switch, the PDK-equipped GT3 features a shifter that looks almost identical to the manual gearbox’s lever.

The other main new cabin feature is a ‘track screen’. When selected, this reduces the information displayed on the two digital displays located either side of the central rev counter to essential information needed on track, such as tyre pressures, oil pressure and temperature, water temperature and fuel level. A motorsport-derived shift assistant provides coloured bars to show revs on these screens, along with a shift-up light.

Performance



Despite the increased width and additional tech over its predecessor, the car has a claimed kerb weight of 1,418kg with the 6-speed manual gearbox and 1,435kg with the 7-speed dual-clutch PDK automatic.

The use of carbonfibre-reinforced plastic (CFRP) to make the front bonnet, lightweight glass, “optimised” brake discs and forged alloy wheels are listed alongside a lighter rear seat compartment cover as reasons for the model being only around 5kg heavier than its smaller predecessor.

Furthermore, a lightweight exhaust system, which saves 10kg, features “infinitely” adjustable flaps to ensure a “highly emotional sound experience” while still meeting the latest emissions and noise regulations.

The 4.0-litre naturally aspirated flat six is adapted from the track-only GT3’s and is “practically unchanged” from the unit to be used in the latest GT3 Cup racing car, according to Porsche.
Its 510hp is the same as the limited-run 911 Speedster and 10hp more than the 991.2-gen GT3 and allows the car to hit a top speed of 320kph (318kph with the PDK gearbox) – higher than the last GT3 RS. It can also cover 0-100kph in 3.4sec. The engine, as with the old GT3’s, is capable of revving to a screaming 9,000rpm.
