Race-winning GB4 Championship driver Enzo Hallman has joined Hillspeed for the 2026 season, and the Swedish racer has his eyes firmly set on a title challenge in his sophomore year in the category.

The 18-year-old, from Jönköping in southern Sweden, returns to GB4 after ending the 2025 campaign ninth in the final driver standings with one race victory to his name at Oulton Park, plus two other podium finishes. 

Hallman began his motorsport career in karting in 2018 in his home country, with his biggest success coming in 2021 when he became Swedish Junior 125 Karting Champion. He also made his international karting debut in that same year, competing in the prestigious Andrea Margutti Trophy and the IAME Warriors Final.

Debuting in cars in 2023 in the NXT Gen Cup in Sweden, the world’s first electric junior touring car series, Hallman was fourth in the standings with a total of six podiums. Continuing in the category in 2024, which this time raced in Germany as support to the DTM series, he ended the campaign third in the championship with nine podiums from 13 races.

That year also marked his single-seater debut in Formula Nordic where, as a privateer, Hallman was Vice-Champion despite missing the opening weekend. He took one overall win and two more outright podiums, as well as four further Formula Nordic class wins when the series linked-up with Nordic 4. 

After winning the Ronnie Petersen Memorial Fund Scholarship in early 2025, Hallman stepped-up into GB4 where he claimed his first podium in only the third race at Donington Park with second place, then going on to take another podium in round seven at Oulton Park followed by his first win in round nine.
