How a BTCC support series demonstrates British single-seaters’ turnaround in fortunes A packed Formula 4 grid looks guaranteed to deliver action and entertainment – who are the rising stars setting out to make a name for themselves in 2026? There’s also lots to look out for in Porsche Carrera Cup GB, Caymans and JCW Minis There was a time, not so long ago, when top-level single-seater racing in the UK was in the doldrums.
