In 2022, Hyett made his racing debut at the
Watkins Glen circuit in the
GT World Challenge America series, driving for Team Hardpoint alongside
Gunnar Jeannette. The duo subsequently partook in the final round of the
Le Mans Cup prior to moving into the
LMGTE Am class of the
FIA World Endurance Championship. Led by pro driver
Ben Barnicoat, Hyett and
Jeannette finished second on their first WEC outing at
Bahrain. Having formed
AO Racing in the autumn of 2022, the Hyett and Jeannette duo partnered with WEC outfit
Team Project 1 to contest the full season in
2023. As well as that, Hyett took part in the GTD class of the
IMSA SportsCar Championship, driving together with
Sebastian Priaulx. The campaign did not prove fruitful, as Hyett missed out on any podiums in addition to suffering a crash in qualifying which made him miss the
6 Hours of Spa-Francorchamps due to a back injury. Hyett experienced a turnaround during the winter, where he partnered
Paul-Loup Chatin and
Harry Tincknell in the
LMP2 class of the
Asian Le Mans Series. After two top-five finishes at
Sepang, Hyett scored the first pole position of his car at the
Dubai Autodrome. Though he and his
Proton Competition teammates finished a lowly eighth in the teams' standings, Hyett had demonstrated improved pace in the leadup to a full-time switch to the category, as he and Chatin paired up for
AO Racing in the
IMSA SportsCar Championship. Hyett also took part in the
24 Hours of Le Mans in 2024, driving an AO Racing
Oreca 07 run by
TF Sport alongside
Louis Delétraz and
Alex Quinn. In 2025, he won the LMP2 Pro-Am class and finished on the overall LMP2 podium. ==Racing record==
