2026 Porsche 911 Turbo S with eTurbo Technology
The 992.2 generation Porsche 911 Turbo S is equipped with eTurbo technology. Unlike conventional turbochargers, eTurbos are each equipped with an integrated electric motor.
Porsche 911 Turbo S with eTurbo Technology
The electric motor is located between the compressor and turbine wheels and drives the shaft of the turbocharger directly. As a result, it spools up the turbo at lightning speed, regardless of the engine load. Full boost pressure is always available within a very short time. The eTurbos therefore make a significant contribution to the responsiveness, performance and efficiency of the drive system.
In addition, the turbochargers are designed in such a way that their electric motors can be used to regulate the boost pressure. They generate electrical energy from the rotation of the shafts. While reducing the turbine speed in the process, they reduce the charge pressure as required. The recovered electrical energy is either fed into the high-voltage battery or passed directly to the electric motor in the PDK housing. In this way, excess boost pressure is not blown off, as is normally the case, but instead used to generate energy. Wastegates are therefore not necessary.
Twin-Turbo Layout
The twin-turbo layout makes it possible to reduce the size of the individual turbochargers, which have been specially designed to meet the specific requirements of the 911 Turbo S. Reduced diameters of 65 mm for the turbine wheel and 73 mm for the compressor wheel bring even greater responsiveness. In addition, the use of the second turbo increases the capacity of energy recuperation from exhaust gases.
At full throttle, the electrical power gained in this way is deployed by the electric motor in the PDK housing, significantly improving overall performance. The maximum combined system torque of the 992.2-generation Porsche 911 Turbo S is 800 Nm and is available over an extremely wide rev range from 2,300 to 6,000 rpm. The maximum power output of 523 kW (711 PS) is delivered from 6,500 to 7,000 rpm.
