Inside the New Porsche 911 Hybrid Powertrain

Electrifying the Porsche 911 was never going to be easy. Add too much weight, and you ruin the handling. Change the character of the flat-six engine, and you alienate the purists. With the new 992.2 Carrera GTS, Porsche has introduced the 'T-Hybrid' system—and it is a masterclass in compromise.
The system is not a plug-in hybrid. There is no heavy, high-capacity battery pack that allows for 30 miles of electric-only driving. Instead, Porsche opted for a tiny 1.9 kWh battery operating at 400 volts, mounted in the front trunk where the 12-volt battery used to sit.
This battery powers an electric motor integrated directly into the new 8-speed PDK transmission, providing up to 54 hp of assist. But the real magic is the electrified turbocharger. An electric motor sits between the compressor and turbine wheels, capable of spinning the turbo up to speed instantly. This entirely eliminates turbo lag.
The result? The GTS now hits 60 mph in 2.9 seconds, handles better thanks to a lower center of gravity, and only gained 103 lbs compared to the previous generation. It is electrification used purely for performance, not efficiency.
