Early career
Born in Auckland, New Zealand, Cassidy started racing at a young age, starting his karting career at just six years old - taking on the likes of future Formula E race winner Mitch Evans, as he made his way up the ranks.
Graduating to single-seaters, Cassidy set off with a winning debut in the Formula First New Zealand series in 2008, before eventually becoming one of the most successful drivers in the history of the Toyota Racing Series.
After back-to-back championship victories in the Toyota Racing Series, Cassidy travelled to Europe to take on the FIA Formula 3 European and Renault 2.0 championships. The New Zealander also got his first sampling of street racing with an impressive third-place finish in his first-ever appearance at the challenging Macau Grand Prix.
Cassidy then branched out into Japanese motorsport, taking on dual driving duties in the Super Formula and Super GT championships. Driving for the legendary TOM'S racing outfit, the Kiwi continued his rise in Japan, winning the Super GT title in 2017 and the Drivers' Championship in the 2019 Super Formula season.
Formula E | 2020-23
After a star appearance topping the timesheets at the 2020 Marrakesh Rookie Test, Cassidy jumped back into the seat with Envision Virgin Racing for his debut in the 2020/21 ABB FIA Formula E World Championship.
Cassidy consistently impressed and a storming second half of his season yielded two trips to the rostrum in Puebla and New York City. His second season yielded more progress as the Kiwi continued alongside Robin Frijns at the team - firing to 11th overall in the drivers’ standings, thanks to a maiden victory in New York City and a further podium in London added to his tally.
The 2022/23 season saw Cassidy partner with Formula E World Champion Sebastian Buemi, and the two led Envision to its first Teams’ championship. The charge was led by Cassidy who claimed four wins, three second places and a third place, as he narrowly missed out to Jake Dennis in the Drivers’ Championship.
Formula E | 2023-25
For 2023/24, Cassidy joined forces with his compatriot Mitch Evans at Jaguar TCS Racing, with the pair looking to guide the iconic British outfit to their inaugural Teams’ Championship.
The New Zealander immediately got up to speed with the factory squad, taking podiums in Mexico City and Diriyah before taking victory in the second race in Saudi Arabia. Another win alongside four podiums on the bounce followed as Cassidy put himself right in the frame (once again) for championship honours. However, an error while in the lead in the closing stages in Portland put Cassidy out of the race for the title.
Cassidy remained with Jaguar for the 2024/25 season, which started with a huge crash for the New Zealander, as he was involved in the accident that left Pascal Wehrlein on his roof. After such a dramatic start to the year, it wasn't until Round 7 that Cassidy returned to the podium and the form that we’ve come to expect from him. A third in Monaco, victory in Shanghai and then a hat-trick of wins to close out the season in Berlin, and a clean sweep with both wins in London, put Cassidy right in the frame for a championship fight in the following season.
Formula E | 2025-26
The 2025/26 season marked a fresh start for Cassidy with a new powertrain and a new team, completely, as legendary French manufacturer Citroën joined the paddock. Across the garage, Cassidy was joined by Formula E’s only back-to-back champion, Jean-Eric Vergne.
The pair worked tirelessly to get the French squad quickly up-to-speed in the championship, with immediate success for Cassidy in the form of a third-place finish in the opening round of the season. A victory followed in Round 2, but inconsistency in achieving points scoring results ruled out hopes of a title challenge from the New Zealander.
Citroen Racing continue with an unchanged driver line-up for the 2026/27 Formula E season, as drivers and teams prepare to get to grips with the all-new GEN4 machinery.
