It's all change for 2023 with a very different feel to the British Touring Car Championship support series line-up. After over a decade with two series on the bill, Ginetta has departed. Instead, the Porsche Sprint Challenge GB Cayman series joins the support package on a full-time basis. Plus there are plenty of intriguing guest categories also due to appear.
But, even among the championships remaining on the TOCA undercard, there is still no shortage of change. Just a couple of the top 14 drivers from last year's Mini Challenge standings are continuing this season as a host of new names join the fray, while there has also been an influx of new faces in British Formula 4. With an intriguing Porsche Carrera Cup GB title battle also in prospect, there's lots to keep an eye on, starting at Donington Park this weekend.
