Carspotter Jeroen has filmed a prototype of the upcoming Porsche 911 ST 992.2 at the Nürburgring Nordschleife, providing clues on what we can expect from the new model. The car is rumored to be based on the 992 GT3 Touring and is reportedly going to be equipped with the same 4.0-liter, 510 horsepower naturally aspirated flat-six engine paired to a six-speed manual gearbox. The ST development car has design elements similar to the latest 911 Sport Classic, including a double-bubble roof and Gurney flap, and has unique profiles and wheels.
