GB4 has announced its first races outside Britain, joining GB3 in Spain's Copa del Sol in February 2027. The organiser's 7 October announcement sets out three meetings and nine races ahead of the main British season.
The provisional calendar lists MotorLand Aragón on 13–14 February, Jarama on 20–21 February and Jerez on 27–28 February. Each meeting has qualifying and one race on Saturday, followed by another qualifying session and two races on Sunday.
The programme includes pre-event testing: two days at Aragón and Jerez, and one at Jarama. Entry fees, including that testing, are capped at £3,250 plus VAT per event.
Registered as a Spanish national series, the competition will admit drivers aged 15 and over. Teams can run four cars, one more than in the main GB4 championship, which begins at Snetterton in April.
The dates remain provisional in the published announcement. Full regulations and further entry details were still to be issued when the series was unveiled.
