The 15-year-old is making the switch to single seaters after an extremely competitive 2022 campaign in the Ginetta Junior Championship.
The Wroxham-based driver took the Rookie title, plus six race victories and a further nine overall podiums en route to second outright in the standings.
Macintyre said: “I am really looking forward to racing with Hitech in ROKiT British F4.
“Their results last season were brilliant and it’s clear for me that this was the right team to drive with, as they not only help develop me as a better driver, but also win races.”
The British driver is also aiming high for his first season in British F4: “The goal for next year is to get at least top three in the championship, Hitech have got a really good car and I feel like if I push myself hard enough throughout the winter we can get there and fight at the front.”
The Ginetta Junior Championship has been a proving ground from drivers stepping into single seaters.
Hitech’s team manager, Dominic Stott, is pleased to have Macintyre join the team and they look to defend their Teams Cup crown next season.
“I’m delighted to welcome Will to the team for 2023,” adds Stott.
“The success we have had this year is a testament to the hard work everyone at Hitech GP has put in for our first year in F4. Having already conducted a focused test programme, we know we still have a lot of work to do but aim to hit the ground running in January.”
Macintyre is the fifth driver to be confirmed for 2023 after Dion Gowda, James Higgins and ROKiT Racing Star competition winners Monica Boulton Ramos and Deagen Fairclough.
British F4 has a 10-event, 30-race season lined up for next season, commencing on the 22-23rd of April at Donington Park. The series will also utilise the Silverstone Grand Prix circuit for the first time.
