Full Electric Powertrain

GFG Sibylla

Key project requirements

|   Full EV prototype
|   Maximum speed over 200 km/h
|   Acceleration 0-100 km/h 4 sec

Podium Advanced Technologies designed and built the electric powertrain and custom battery pack of the Sibylla GG 80 by GFG Style, a four-door luxury sedan that incorporates innovative solutions in terms of accessibility, functionality, and aesthetics.

Working for Superstile – the Turin based specialist in show cars, master models, maquette and prototypes who built the GFG Sibylla GG80 – Podium designed and built the custom battery pack, the powertrain and the rear suspension system.

The choice of electric propulsion enhanced the interior space and allowed Giorgetto and Fabrizio Giugiaro to revolutionize accessibility and exploit this space by introducing rational, functional, ergonomic solutions both inside and outside of the vehicle.

Sibylla’s maximum speed is over 200 km/h with an acceleration 0 – 100 km/h in 4 seconds.
