Tommy Harfield is a British single-seater driver competing in the British F4 Championship for Chris Dittmann Racing. Over two seasons from 2025 to 2026, he has scored three wins and eight podiums from 29 starts, with an average finish of sixth place. His Racer Rating of 4,008 places him at the professional level of an entry-level single-seater field; he has beaten several stronger drivers on occasion, including former British F4 champion Fionn Mclaughlin in nine races and Jimmy Piszcyk, a front-runner in the series, in ten.[1]
Harfield's head-to-head record against his most frequent rivals shows a split picture. He has finished ahead of Henry Mercier and Cole Hewetson in nearly all their shared races, demonstrating dominance over weaker competitors in the field. Against drivers of his own calibre, however, the balance is closer; he trails Jimmy Piszcyk by four races over 24 starts and holds a narrow advantage over both Ethan Jeff-Hall and Martin Molnar, each of whom he has beaten in roughly half their encounters. This pattern is consistent with a driver solidly positioned in the upper half of a national-level feeder championship but not yet commanding it.[2]
His 2025 season was productive enough to earn the Jake Cook Memorial Award, and he was retained by Chris Dittmann Racing for 2026 with stated ambitions toward the championship. The first three rounds of 2026 have yielded no wins or podiums, suggesting the title campaign may have stalled; his current status within the year remains unresolved.
