New 2023 Porsche 911 GT3 RS spied testing high in the mountains

The last time we saw the Porsche 911 GT3 RS, it was hustling around the Nurburgring race track. That’s the car’s natural habitat, but a new spy video from TFLnow captures the high-performance coupe somewhere you wouldn’t expect it – high in the mountains.

Porsche hasn’t done much to hide the car’s wicked styling, and there are plenty of signs it will have a host of significant upgrades over the standard GT3. The big wing hanging off the back is the attention-grabber, but the car will have several tweaks that help its aerodynamics and cooling. The swan-neck wing could be capable of making active adjustments, switching between high-and low-downforce configurations.

While it looks like the Porsche is fully exposed, the automaker still conceals the coupe’s finer details under the devious black tape. Many of the car’s visual upgrades are designed to enhance the car’s performance. Extra ductwork and vents improve airflow around and through the car while keeping everything at the correct operating temperature. The rear quarter panels will have vent openings, too, but they’re one of the few styling bits Porsche is hiding.

We don’t know what powertrain the GT3 RS will arrive with, but it should be the naturally aspirated 4.0-litre flat-six. Rumours suggest that it’ll spin to 9,500 RPM; however, we’re clueless about its output. The car isn’t about all-out power and blistering quarter-mile times.

It should make close to the previous-generation GT3 RS’s output of 520 bhp (387 kilowatts). Porsche could wring a few extra ponies out of the powertrain for the new model, and it sounds like Porsche will pair the engine with a dual-clutch gearbox. Everything about the car is designed to improve its chances around the race track.

The Porsche 911 GT3 debuted in February 2021, packing 502 bhp (374 kW) under its bonnet. However, we don’t know when the hotter GT3 RS will break cover. We expect Porsche to reveal the new 911 before the end of the year. Deliveries could begin before the end of the year as well, but Porsche could stagger the car’s rollout in different markets.
