Listen To The Porsche 911 GT2 RS Engine Hiding Inside A 911 GT3 RS

A new video posted to YouTube has captured what at first appears to be a regular Porsche 911 GT3 RS getting ready for some runs on the Nürburgring, but closer inspection reveals that this is likely a test mule carrying a developmental version of the engine that will appear in the next GT2 RS. Clues include a laptop computer mounted on the passenger side of the dashboard and a relatively crude roll cage, but these could simply be evidence of Porsche’s engineers looking to further refine the GT3 RS for its next facelift. What gives the game away is the exhaust tone, which exhibits plenty of whistling from the turbocharged boxer engine. Take a listen below.

Brutal Acceleration

The sound of the engine at low revs is intimidating enough, but a few squirts of the loud pedal when the engine is under more load suggest loads of horsepower, and the speed that the test driver carries through corners is impressive, even without the GT2-specific upgrades that the 911 range-topper will inevitably get. We know that Porsche does not prioritize output numbers above the driving experience, but we can still expect some healthy figures, with most reports indicating the GT2 RS will feature a 700-horsepower mild-hybrid powertrain.

Speaking of upgrades specific to the GT2 RS, several patents discovered by CarBuzz in the last year look perfect for a hardcore track toy like this. One of the more interesting is a system for remote camber adjustment, allowing the driver to adjust suspension alignment on the fly. Such innovations may have once seemed like science fiction, but the GT3 RS has a remotely adjustable diff and variable suspension whose settings can be customized on the fly, so it’s not a stretch to imagine that the GT2 RS could raise the bar yet further.

But it seems that Stuttgart wants to debut this tech on the Taycan or perhaps even the Macan EV.

ETA: 2026

Porsche has yet to publicly confirm anything concrete about the GT2 RS, but it is believed that a debut will take place in 2026, and it’s quite possible that its MSRP will exceed $300,000. A manual transmission is highly unlikely as the GT2 RS is a showcase of all the technology that Porsche has at its disposal to make a rear-engine sports car as fast as possible, and a manual would stunt progress slightly. Similarly, the hybrid system will almost exclusively enhance performance, with any fuel savings likely to be negligible, just as is the case with the newly unveiled 911 GTS hybrid. We can also expect Stuttgart to improve on the 991.2’s astounding Nürburgring lap time of 6:47.3.
