In June 2018, ahead of the 2018 24 Hours of Le Mans, the FIA first confirmed that the new set of top-level prototype regulations would feature design concepts based on hypercars when implemented, with a summary of the new technical regulations being presented to the FIA World Motor Sport Council in Manila. At the time, Toyota, Ford, McLaren, Aston Martin, and Ferrari were revealed to have been in roundtable meetings with the championship organisers for the new regulations, with a significantly reduced targeted full-season budget in the region of 25 million euros—75% lower than existing budgets used by manufacturer teams.
