2023 Porsche 911 GT3 RS spied testing at the Nürburgring, August reveal confirmed

UPDATE, July 28: Porsche 911 GT3 RS to debut next month, less power than before

The 2023 Porsche 911 GT3 RS will be unveiled on August 18, the brand has announced.

As the track-orientated flagship of the 911 range, the teaser image reveals wild aerodynamic enhancements, with a massive two-tiered rear spoiler and larger bonnet vents.

However, Porsche has confirmed the 911 GT3 RS will share its 4.0-litre naturally-aspirated flat-six engine with the GT3, producing around 500PS (378kW).

The regular GT3 has 375kW, with a seven-speed dual-clutch transmission and a claimed 3.4-second 0-100km/h sprint time.

A six-speed manual transmission could be offered for the new-generation GT3 RS; however, it is likely to remain an auto-only proposition, as with the outgoing model.

"The new 911 GT3 RS is even more optimised for track use than its predecessors," said Andreas Preuninger, director of Porsche's GT model line.

"The spontaneously responsive, high-revving four-litre, six-cylinder boxer engine with approximately 500 PS has proven ideal for use at trackdays and club sport events."

UPDATE, June 29: Porsche 911 GT3 RS spied testing at the Nürburgring

Porsche has returned to the Nürburgring for further testing on its new 992-generation 911 GT3 RS.

The latest in a long line of flagship 911s, the upcoming GT3 was pictured last week on the outskirts of the Nordschleife, with Porsche applying minimal camouflage to disguise the yet-to-be-revealed RS.

Fast forward a few days and it has been spotted on-track at the Nürburgring by CarSpyMedia, coming up against BMW's new M2 among other cars at the circuit in hot pursuit of the "standard" GT3's 6:59.927 benchmark.

June 22: Porsche 911 GT3 RS spotted without disguise

Porsche's newest 911 GT3 RS has been spied without camouflage, leaving little to the imagination for the hardcore, track-focused model.

Based on the latest 992-generation Porsche 911, the upcoming GT3 RS builds on the already strong formula of the "standard" GT3, amplifying features such as the bonnet air vents, prominent front splitter and gigantic swan-neck rear spoiler.

Compared to the GT3, Weissach has turned it up to 11 for the RS's aerodynamic package, with fins sticking out of the front bumper and behind the front and rear wheels to clean up the airflow, while vents on the front and rear guards help channel the air to the active rear wing.

Those with keen eyes will also be able to spot a pair of fins on the roof just in front of the rear window, likely providing extra high-speed stability rather than acting as a roof-rack mounting system.

Looking underneath the car in low shots we can also see a number of fins on the floor, suggesting Porsche is aiming to gain more downforce than ever before by leaving no surface untouched.

Power is expected to come from Porsche's 4.0-litre naturally-aspirated flat-six engine, producing 375kW and 470Nm in GT3 guise – although it's unlikely the six-speed manual gearbox will carry across, with the seven-speed dual-clutch PDK remaining.

Those who can't wait – or fork out the money – for an RS, can purchase the GT3 MR package from Porsche's factory-backed skunkworks Manthey-Racing, which includes a number of upgrades that help reduce the GT3's Nürburgring time by almost six seconds to a 6:49.656.

The 992 GT3 RS has big shoes to fill as the 911's flagship grade, given the base GT3 took out this year's MOTOR Performance Car of the Year award with a near-flawless performance across the five-day test.
