Compare equivalent power units and test conditions. Porsche’s 711 PS is a metric-horsepower figure, not 711 U.S. mechanical horsepower.
What to know
Porsche’s September 2025 reveal of the new 911 Turbo S introduced a twin-turbo T-Hybrid powertrain with 523 kW, or 711 PS, of combined output. Its six-cylinder engine remains part of the familiar 911 formula.
Two electric exhaust-gas turbochargers are a key change from the single-eTurbo setup described for the Carrera GTS. Porsche says they improve response as well as support higher performance. A compact battery and an electric motor integrated into the transmission complete the hybrid arrangement.
Our take: sharp response can be as exciting as a higher cylinder count. Porsche is using electrical assistance to build on the flat-six experience. Alongside the V8s, V10s, and V12s in our Soundtrack features, this is a reminder of how many different ways there are to make a compelling performance car.
