The tweaked qualifying format was first trialled at Snetterton in 2020 and features the regular 30-minute qualifying session followed by a short five-minute break before a 'Top 10 Showdown' is then held over 10 minutes to set the front five rows of the grid.
It was used at three events in 2021 but not at all this year - however, with the number of support series reducing from five to four for 2023, there is now more flexibility in the timetables and the alternative format will be used at the season-opening Donington Park round, as well as at Brands Hatch (Indy layout), Oulton Park, Knockhill and Silverstone.
