Hear The Porsche 911 GT3 R Rennsport Rev Up To 9400 RPM

Bearing the namesake of the event that it headlined, the Porsche 911 GT3 R rennsport leaves nothing on the table when it comes to defying conventional 911 thinking. It’s wild to think how Porsche could’ve pulled that off, given how capable and raw the latest 911 GT3 RS is as a production car and even how the aforementioned S/T, in its own way, took things even further.

As “not a race car” and not being certified for public road use, the GT3 R rennsport exists in a bit of a grey area where they’re best suited for private collectors—the super-limited production run of just 77 units, costing a cool $1,046,000 each, all but seals the car’s fate as such.

Amongst a number of notable features, the GT3 R rennsport utilizes a special 4.2L flat-6 engine, previously exclusive to the race car it is based on. No longer bound by series rules and restrictions, the naturally-aspirated boxer produces 612 bhp—up from the GT3 R’s 557 bhp—and now screams on its way to an astronomical 9,400 rpm redline. The exhaust note is about as mesmerizing a sound as you can imagine.

To prove that the Porsche 911 GT3 R Rennsport has a unique sound of its own, Porsche released video wherein they strapped in seven microphones inside, outside, and in the engine bay for maximum audio experience. Watch the video below and listen to Porsche 911 GT3 R rennsport  revs up to 9400 rpm.
