The 2025 Porsche 911 GT3 (992.2) is powered by the same 4.0‑liter naturally aspirated flat‑six engine as its predecessor (992.1 GT3), delivering 503 hp and 332 lb‑ft (450 N·m) of torque (a minor drop due to added emissions hardware), to a 6-speed manual or a 7-speed PDK transmission, both with drivetrain ratios shortened by 8% to sharpen responsiveness. Similar to 991.2 and the 992.1 predecessors, this variant is also offered in winged and wingless/Touring trims. The refreshed model introduces aerodynamic enhancements—including a redesigned front splitter, diffuser, aero bars previously reserved for the GT3 RS, and updated rear wing endplates—as well as increased use of carbon-fiber reinforced plastic (CFRP) for weight reduction. Notably, the Weissach Package becomes available for the first time on the GT3, offering additional lightweight CFRP components.
