T-Hybrid
Porsche's performance hybrid system for the 911: an electric motor inside the eight-speed PDK gearbox plus electrically assisted turbochargers, fed by a small 400-volt battery. It exists to remove turbo lag and add torque, not to drive on electricity alone.
Example
The Turbo S combines a 640 PS flat-six with a 52 kW e-motor for 711 PS and 800 Nm.
