The 24-year-old Briton will contest all five 2024 IMSA Michelin Endurance Cup events, starting with the Daytona 24 Hours in January.
Hanson became the first driver to win the FIA World Endurance Championship’s LMP2 title, European Le Mans Series crown and score P2 class victory at the Le Mans 24 Hours all in the same year in 2020.
He has already contested multiple IMSA events, including Daytona, the 12 Hours of Sebring and Six Hours of The Glen with United Autosports in P2.
“I'm very excited to be joining JDC-Miller Motorsport for the 2024 IMSA endurance races,” said Hanson, who has driven exclusively for United since 2018.
“After my first taste of IMSA back in 2018, I am thrilled to be back in the IMSA paddock and above all, to be making my debut in the GTP class with JDC's 963 Porsche.
“I can't wait to see what we can achieve.”
Hanson is also the youngest driver ever to win a WEC title, the youngest Asian Le Mans Series LMP3 champion, and the youngest ALMS and ELMS outright race winner.
To date he has seven class wins in the WEC, and 11 wins in the ELMS, including two last weekend at Portimao to finish runner-up in the standings.
