The object
Alan Cocconi designed the propulsion systems behind the GM Impact prototype and AC Propulsion's tZero electric roadster. Its high-power AC drive and battery architecture showed that an electric sports car could be rapid and usable, directly influencing the technical direction of the original Tesla Roadster.
What Alan did
Designed the AC Propulsion tZero's high-power AC electric drivetrain after designing propulsion systems for the GM Impact prototype.
Why it matters
IEEE Spectrum reports that tZero technology was incorporated into Tesla's first production vehicle, while the Caltech heritage interview documents Cocconi's foundational power-electronics work.
Living-status check
IEEE Spectrum published Cocconi's current author profile in March 2025, positive dated evidence he was alive in 2025.
