The updated 2025 Porsche 911 GT3 unveiled earlier this month may be the last time Porsche's track star is offered without turbocharging or hybrid technology.
In an interview with Autocar published on Tuesday, Andreas Preuninger, Porsche's head of development for GT-badged cars, said stricter Euro 7 emissions regulations planned by the European Union for introduction in 2026 may make it impossible to continue with a naturally aspirated engine that still delivers the performance expected of a GT3.
“I don’t think we can handle Euro 7 without electrification or without turbos,” he said. “We can sell [the updated GT3] for another two years, but it depends on the markets.”
The updated GT3 sticks with a 4.0-liter flat-6 rated at 502 hp. While those numbers are unchanged from the previous model, Preuninger said getting the engine to meet current Euro 6 regulations was a challenge. For example, it delivers a third less nitrous oxides and 40% less particulate emissions, he said.
When asked whether the new 473-hp hybrid powertrain in the updated 2025 911 Carrera GTS range could be used in the GT3, Preuninger downplayed the chances. He told Autocar that the hybrid powertrain would mean using the dual-clutch transmission found in the Carrera range instead of the lighter sport version used in the GT3.
This means Porsche may develop a new hybrid system for the next GT3 or go with a turbocharged engine.
Regardless of the solution, Preuninger told Autocar it isn't something GT3 buyers actually want—because it adds weight to the wrong end of the car, "at the back.”
