Formula E: Andretti signs Callum Voisin as development driver for Gen4

Andretti has signed Callum Voisin as a development driver for the upcoming Gen4 season of Formula E. The 22-year-old Briton will primarily support the team with simulator work and preparations for race weekends. Voisin already has Formula E experience from rookie tests with Cupra Kiro and Andretti.

Voisin gained his first experience in the all-electric racing series at the 2025 rookie test in Berlin with Cupra Kiro, where he finished fifth overall. In March 2026, he tested for Andretti for the first time in Madrid. As a development driver, he will now be involved in the setup and development of the new Gen4 car.

Voisin won the British GB3 Championship in 2023 before moving to Formula 3, where he claimed a race victory at Spa-Francorchamps in 2024. In 2026, he won the Porsche Carrera Cup Great Britain title with nine victories. At Andretti, he joins a driver line-up featuring race drivers Jake Dennis and Felipe Drugovich. The American team is switching from Porsche to Nissan powertrains for the Gen4 era.

Welcome to the team, Callum 🙌 https://t.co/nwQmELU5us
