The series brings together a mix of GT3 and GT4 machinery that compete at the twelve 1 hour-long races spread across six events and five countries.
Two types of driver pairings compete for outright victories: the mix of a professional and amateur (Pro/Am) and two professionals graded no higher than Silver by the FIA (Silver Cup). The latter will be subject to performance adjustments and approval by SRO to ensure that both Pro/Am and Silver/Silver crews are capable of winning races outright.
