Based on the latest 992-generation 911, the new 911 GT3 R produces up to 565 PS
Porsche will be officially unveiling the new 911 GT3 R to the public at this year’s 24 Hours of Spa-Francorchamps.
From the 2023 season, Porsche customer teams can campaign the new racing vehicle in worldwide motorsport events that adhere to the GT3 regulations.
Based on the latest 992-generation 911, the new 911 GT3 R features a larger engine producing up to 565 PS, a more constant aerodynamic performance and an optimised vehicle balance.
In case you're wondering how much the car costs, Porsche Motorsport now offers the new 911 GT3 R at a price of 511,000 Euros plus country-specific VAT and optional extras.
After the GT3 class was announced as a professional category in the North American IMSA series, the FIA WEC World Endurance Championship followed suit as GT3 racing cars such as the new 911 GT3 R will be eligible to take part in the 24 Hours of Le Mans for the first time from 2024 onwards.
Like in the previous model, the new 911 GT3 R is powered by a water-cooled flat-six engine with four-valve technology and direct fuel injection. The main new development is the displacement.
Like the 911 RSR, the capacity of the new 911 GT3 R has increased by a good five per cent from 3,997 to 4,194 cc.
This has boosted the engine’s peak output to around 416 kW (565 PS). First and foremost, however, Porsche has optimised the torque and power curve across the entire rev range. Consequently, the new 4.2-litre six-cylinder is better suited to gentleman drivers.
The high-revving six-cylinder manages without turbocharging and sits in the classic rear position, thus enhancing traction and braking. However, it has been tilted forwards by 5.5 degrees, creating more leeway for the underbody diffuser.
Auxiliary units such as the alternator and the air conditioning compressor were moved a good metre forward and further down into a space in front of the engine and gearbox, which has a positive effect on the weight balance of the 911 GT3 R.
The sequential six-speed contest-mesh gearbox is derived from the current 911 GT3 Cup. Shift paddles control an electronic shift drum actuator that enables particularly rapid and precise gear changes.
The new 911 GT3 R’s suspension – many details of which have been modified – supports driveability, allows more precise steering, ensures less wear on the rear tyres and reduces the time spent on set-up changes. For this, numerous components and technical solutions were taken from the 911 RSR.
At the front axle, a state-of-the-art double wishbone layout controls the wheels. The rear axle sports a multi-link design. The KW shock absorbers were further improved and offer five adjustment settings. Set-up modifications are done with so-called shims.
These plates enable precision adjustments without the need for the time-consuming re-alignment of the suspension afterwards.
The optimised positioning of the central pivot points at the front axle frees up space for the aerodynamic “race underfloor” concept. Like in the 911 RSR, this elevated underbody allows for a clean flow of air to the rear diffuser and reduces the pitch sensitivity of the racing car – i.e. a high rake under braking.
The rear wheels have moved a little further back, which extends the wheelbase from 2,459 to 2,507 millimetres. This also reduces the load on the rear tyres and improves the consistency of the tyres’ performance over longer stints.
In addition to the aluminium monobloc racing brake callipers, the brake discs on the new 911 GT3 R are now also supplied by the specialist company AP. The internally vented and slotted front steel discs measure 390 mm in diameter and are activated by six pistons.
Fitted at the rear are four-piston callipers and discs measuring 370 mm. A sophisticated software application for the fifth-generation racing ABS reduces wear on the tyres and brakes. Porsche's traction control system also received a further development.
The new 911 GT3 R is just the second racing car from Porsche Motorsport to be based on the current 992-generation 911 after the 911 GT3 Cup. Its lightweight body with an intelligent aluminium-steel composite design draws on the production model, albeit with major modifications for use in the 911 GT3 R.
Almost all body components are made of lightweight carbon, including the front and rear lids, doors, side panels, rear wing and roof. The wheel arches are made of aramid fibres.
Inside, the seat has moved closer to the centre of the car. This enabled Porsche to optimally adapt the more ergonomic seat position to the improved roll cage and the newly developed FIA side impact protection.
