The 16-year-old enjoyed a successful karting career, winning back-to-back Winter Cup titles in Valencia in 2020, before representing Great Britain in the FIA Karting Academy Trophy a year later.
Harrison said: “Taking this step up into single-seaters is a massive change, so it’s going to take some time to adapt to that, but I’m really excited. I hope that together with Chris Dittmann Racing, we can have a really successful year.
“We made a lot of progress during the test days I did with the team earlier this year. I enjoyed every moment of it, which is very important. I progressed the most within myself and on the timing screens when I was with Chris Dittmann Racing, so I knew they were going to be the right fit for me going into the F4 British Championship.”
The British driver admitted it took him a few test days to feel comfortable in the car but is eagerly anticipating the opening round at Donington Park.
“Stepping into the car for the first time, it was a huge change from what I’m used to. It took about five days for me to start feeling more in control of the car.
“We’ll see how the first round at Donington Park goes, but I’m feeling confident. I’ve been working really hard on my preparation for 2024, so I think we’ll surprise a lot of people.”
Harrison becomes the first driver to be announced by Chris Dittmann Racing, in a series that shapes up to be highly competitive.
Deagen Fairclough is returning to the series with JHR Developments, as Abbi Pulling steps back into F4 with Rodin Carlin alongside her F1 Academy campaign.
The Team Owner Chris Dittmann said: “We’re excited to welcome Bart to the team for the F4 British Championship, as he has shown some great potential in the car throughout pre-season testing with us.
“It’s looking like it’s going to be another very competitive grid, so it won’t be easy for Bart coming straight from karting, but I have no doubt we can help him develop quickly and I’m looking forward to a successful season together.”
