The British racer makes the step up off the back of finishing runner-up in the German ADAC Formula 4 Championship, with five wins and a further five podiums to his name.
“I am very happy to continue working with Jenzer Motorsport after a successful test in Jerez,” said Barnard. “We've made good progress over the winter and I'm more than pleased to start the FIA Formula 3 season!
“This is by far the biggest step in my career and it will be a challenge, but definitely one I'm up for! I would like to thank everyone at PHM Racing for this great opportunity that will make it possible for me to drive at Jenzer Motorsport in 2023.”
Barnard made his single-seater debut in 2020 with a partial campaign in Italian F4 before making a full-time switch to German F4 the next year. 2022 saw the 18-year-old finish ninth in Formula 4 UAE, which he followed up with a dual campaign in both Italian and German F4, finishing eighth and second respectively.
The Brit got his first taste of F3 machinery during the post-season test in Jerez last year, recording four top 10 finishes, including topping the final session of running.
Ahead of pre-season testing in Sakhir in a fortnight’s time, Barnard is currently competing in the Formula Regional Middle East Championship, where he sits second in the Standings with one win and three podiums.
Team Principal Andreas Jenzer added: “We got to know Taylor as a very bright driver who doesn't need long to feel good on a new track. This ability will be a huge asset for him given the limited track time in FIA F3 racing events. Taylor immediately shows strong pace and a quick adaptation, although of course it is clear that there is a learning curve for him to do, too. In any case, we are looking forward to the new season together with our drivers very positively.”
