Pembrey announced its first Welsh Motorsport and Supercar Festival on 16 July 2024, scheduling the event for 22 September.
The venue linked the chosen date to the thirty-first anniversary of Ayrton Senna's 1993 McLaren test at the circuit. Its programme combined historic Formula 1 displays, supercars, rally and rallycross machinery, motorcycles and demonstration runs.
Participating organisations included the Castrol MEM Rally Team, Darrian, Viking Motorsport and several owners' clubs. Supercar passenger laps were planned in aid of Morgan's Army, alongside interviews, live music and family activities. The festival was intended to open the inner paddock and other parts of the venue to visitors.
