A 2023 Porsche 911 GT3 RS will debut next month, but its power advantage may wane

It's possible that the Porsche 911 GT3 RS revealed next month will offer fewer horsepower than the model it replaces. With its world premiere on 17 August, the new Porsche GT3 RS is the fastest and most extreme version of Porsche's pre-facelift '992.1' 911.

Although Porsche has hinted that the 992.1 GT3 RS will use the 375kW engine of the 911 GT3, it will be the first GT3 RS with less horsepower. According to Andreas Preuninger, director of Porsche GT vehicles, 'the 911 GT3 RS is even more optimized for track use than its predecessors.

Its spontaneously responsive, high-revving, four-liter, six-cylinder engine produces approximately 500 PS [375kW] compared to the standard GT3. Preuninger hinted in a media statement that the 911 GT3 RS's engine won't be changed in the new model and that the focus was primarily on aerodynamics and chassis.

This would be the first RS-badged Porsche to step back in power if the GT3's 375kW/470Nm 4.0-liter flat-six engine is used - the 992 refers to the most recent 911 generation, while the '.1' stands for the version before the car's mid-life facelift.

In the pre-facelift version, the GT3 RS 991.1 generated 368kW and 460Nm, while the outgoing '991.2' produced 383kW and 470Nm. About 15kW more than standard GT3s at the time, according to these figures.

In 2007, a 3.6-liter flat six-cylinder engine with 305kW/405Nm was shared by the Porsche GT3 RS and the regular GT3.

Porsche reports that despite being 18 months after the reveal of the lesser GT3, the 911 GT3 RS will be the most extreme car to wear the 911 GT3 nameplate, drawing inspiration from 'the successful 911 RSR and 911 GT3 R GT racing cars.'

In spy photos and now in Porsche's official teaser, a hardcore aerodynamic package looks to be one step up from the GT3, with a huge 'swan-neck' rear wing (possibly with a flap to reduce drag).

In addition to the GT3 RS's signature wheel-arch air vents, Porsche has even fitted new doors with traditional door handles instead of the pop-out electric handles found on other 911s.

In keeping with its track focus, and like all recent Porsche RS cars, the new 911 GT3 RS will be equipped with a seven-speed dual-clutch automatic transmission only.

There will be a full unveiling of the 2023 Porsche 911 GT3 RS on 17 August 2022. Next year, the product will likely be launched in Australia.
