NEW 922-BASED PORSCHE 911 GT3 R UNVEILED

Porsche recently revealed their new 911 GT3 R based on the 992-generation 911. The new  GT3 R houses a larger engine than its precursors and boasts improved aerodynamic  performance, handling, and vehicle balance.

Powering the new GT3 R is a larger 4.2-litre engine, based on the 992-generation 911  powerplant. A key upgrade is the 992 GT3 R’s increased engine capacity, which has risen  from 3,997cc to 4,194cc. This has ultimately boosted the engine’s peak power output to  416kW (565PS).

Porsche has also angled the engine forward by 5.5 degrees to create more room for the  underbody diffuser. This in turn has meant that the air conditioning compressor and the  alternator have had to be moved forward, though Porsche says this has aided with the GT3  R’s weight balance.

The GT3 R has double wishbone and multi-link suspension at the front and rear respectively.  These changes minimise wear on the rear tyres and support improved driveability and more  precise steering. The vehicle also makes use of improved KW shock absorbers that offer five  different adjustment settings. 

The new suspension changes have also allowed for the GT3 R’s underbody to be elevated.  Porsche says that these changes, alongside a smooth undertray and a rear diffuser, improve  downforce without dramatically increasing drag, thus allowing the GT3 R to better carry  speed around corners. The new swan-neck mount featured on the rear wing further  contributes to making the GT3 R as aerodynamic as possible.

The wheelbase has also been increased from 2,459mm to 2,507mm, with the rear wheels  moved slightly further back. This change further aids the reduction of stress on the rear  tyres and improved ride quality.

Inside, Porsche has made a conscious effort to ensure that safety remains a high priority.  The seat has been shifted closer to the car’s centre, which has allowed Porsche to better  adapt the seat position to the GT3 R’s upgraded roll cage. Both the steering wheel and the  pedals can be also adjusted in line with the driver’s needs. The 6-point safety harness has  seen an upgrade, with the clasp enhanced to allow for marginally quicker driver changes. 

Development for the 911 GT3 R began in 2019, and it will be ready for competition at the  beginning of the 2023 season. Thanks to changes made by the FIA, for the first time the 992  GT3 R will be eligible to race in 24 Hours at Le Mans.
