After an impressive first year in car racing, the 14-year-old from Cheltenham has partnered with Trevor Carlin’s team for his transition into single seaters.
Zak became the youngest-ever winner of the Rookie Cup with the R Racing team in 2019, finishing 164 points clear of his nearest rival.
He also claimed second in the overall championship, with five podiums in the first seven races and a total haul of 30 trophies across the season.
After mulling over a possible move to Europe for the 2020 season, Zak opted for the British championship to allow him to concentrate fully on his schooling.
He said the opportunity to work with a team which has previously helped the likes of Formula One world champions Sebastian Vettel and Nico Rosberg start out on the racing ladder was also too good to turn down.
Zak said: “I competed in international karting for two years and it was very challenging to strike the right balance between my studies and racing. Competing and testing in the UK will make that much easier.
“The opportunity to join Carlin was also a major influencing factor. Learning and progressing is very important and I am still developing as a driver, so getting the opportunity to work with an established team such as Carlin will undoubtedly help with that process.
“I’ve done some testing with them and I already feel very much part of their F4 squad. If I perform well there is an opportunity to progress with the team, as they are involved in everything up to and including Formula 2.”
In common with his Ginetta Junior campaign last year, Zak will be one of the youngest drivers on the British F4 grid in 2020.
He added: “I will be a rookie again next year but I hope I can develop quickly and get some good results for the team. I will start testing in earnest in February and I’m really looking forward to the challenge ahead.
“I’m not complacent and I’m certainly not making any predictions. It will be tough and competitive and I will have to work hard to achieve success. Working with Carlin and Kokoro Driver Performance, I have the ideal framework to progress. It’s now up to me.”
