Series organiser SRO has confirmed a full 36-car entry for this season's Intelligent Money British GT Championship, which starts at Oulton Park on Easter weekend (7-10 April).
The full-season entry is split evenly between GT3 and GT4 cars, with nine manufacturers represented on the grid. Of the 71 drivers named on in this year's line-up, eight are top-line factory drivers and 10 are current or former champions.
This year's GT3 entry is the largest since 2014, while GT4 numbers have rebounded to pre-pandemic levels.
Reigning champion Ian Loggie's title defence will be boosted significantly by the full-time acquisition of teammate Jules Gounon in their Mercedes-AMG, but he faces a stern test to retain his crown. Swiss-Italian Raffaelle Marciello (Mercedes), a multiple international GT champion, is one of the series marquee signings for 2023, having joined RAM Racing.
The other top-line drivers include Jonny Adam and Ross Gunn (Aston Martin), Rob Bell and Marvin Kirchofer (McLaren), Sandy Mitchell (Lamborghini), and Dan Harper (BMW).
Mercedes-AMG, McLaren, Lamborghini, BMW and Aston Martin will all field machinery in the GT3 category this year, while additional manufacturers including Porsche, Ginetta and Ford are included in GT4.
