Born and raised in Guernsey, Priaulx has followed in the footsteps of his father and grandfather as a third-generation racer. Starting at just eight years old, the prodigious young talent claimed multiple karting titles before making the transition to car-racing in the Ginetta Junior Championship.

Finishing as runner-up in that series in 2017, Priaulx then won races in single-seaters in the F4 British Championship. A successful move into the British GT Championship in 2019 with Multimatic Motorsports ended with him finishing as GT4 vice-champion.

Priaulx then transitioned to racing in the USA, winning in the Michelin Pilot Challenge before storming to a sensational title success in the Porsche Carrera Cup North America in 2021. That led to an exciting move into the FIA World Endurance Championship with Proton Dempsey Racing during 2022.

​

This season, Priaulx is racing in the IMSA WeatherTech SportsCar Championship, as part of the newly formed AO Racing Porsche Team.
