The 2022 Porsche 911 GT3 is the twelfth iteration of the track-ready sports car, including RS variants, coming from Weissach. In an age of downsizing and supercharging, the GT3’s naturally aspirated powertrain is arguably better than it’s ever been. Now we are fortunate enough to hear the famous flat six gun howl up to its 9,000 rpm red line on a dynamometer.

At the rear of the new GT3 is a 4.0-liter flat-six, derived from the engine used by the automaker in its 911 GT3 R race car. The engine should be familiar to Porsche devotees, as it powered the 991 Generation 911 Speedster. The engine features individual throttle bodies, rigid rocker arms and plasma-coated cylinder liners, and more high-performance trickery. Total power is rated at 502 hp and 346 lb-ft of torque at the factory.

While that doesn’t seem like a ton in this age of 800 horsepower supercars, the GT3 is no slouch. With the optional PDK dual-clutch automatic transmission, Car and driver was able to record a 0-60 mph sprint of just 2.7 seconds. Around the Nordschleife, the GT3 is capable of achieving an impressive lap of 6 minutes 59.927 seconds.

The video doesn’t give us good data readings from the dyno, although we do get a quick glimpse of the results from a single scan. The Porsche managed to produce 490 horsepower and 323 lb-ft of torque on the dynamometer, which certainly suggests the factory ratings are a bit low. This is not surprising, however, as Porsche is no stranger to this sort of behavior.

No matter how powerful the track-ready sports car is, it looks glorious to burn dinosaur juice. Hopefully, the synthetic fuel project Porsche is working on keeps that kind of soundtrack alive in the age of electric vehicles.
