The organisers of the Japanese sportscar series face a tricky task balancing three types of cars in the GT300 class, with FIA GT3 machinery mixing it with cars built to SUPER GT's own GT300 rules (formerly 'JAF GT300') and 'Mother Chassis' cars based around a standard chassis.
One model that has struggled in particular in recent seasons is apr's hybrid-powered Prius PHV GR Sport, which is now in its fourth and most likely final season of competition in its current front-engined guise.
