The FIA has mandated a minimum production run of GT3 cars, in an effort to prevent the creation of so-called ‘GT3 prototypes.’
Approved during Friday’s FIA World Motor Sport Council Meeting, at least ten race cars from each GT3 model must now be produced within 12 months of the car’s homologation date and 20 within the first two years.
The new rule is understood to target manufacturers, such as Cadillac, which had produced limited numbers of its GT3-spec car.
Only three Cadillac ATS-V.Rs were built, with none having been made available to customers, during the manufacturer’s three-year factory Pirelli World Challenge program, which has since come to an end.
Other GT3 manufacturers are understood to not yet have met the minimum as well.
It includes Callaway, Honda and Lexus, which are all believed to have produced less than 20 cars since the launch of its respective GT3 models.
The FIA’s rule is strictly related to number of cars produced and not sold.
Honda revealed plans to make 12 of its NSX GT3 cars available to customers this year, while Reeves Callaway told Sportscar365 that a number of Corvette C7 GT3-Rs are set to be produced for customer orders in the coming months.
The current number of Lexus RC F GT3s produced is unclear, but at least six have been built since its launch last year.
Larger-scale GT3 manufacturers, such as Audi, Ferrari, Mercedes-AMG, BMW and Porsche, have all already met the FIA’s new requirement.
Bentley and Nissan, meanwhile, have debuted new-generation GT3 cars this year, with McLaren, Aston Martin and Porsche set to roll out new models in 2019 that would all be required to meet the FIA’s new mandate.
