Red Bull advisor Dr Helmut Marko says that Honda are not yet committed to Formula 1 beyond 2020.
The 2021 regulations are still yet to be finalised, and Red Bull’s principal Christian Horner joked that UK prime minister Boris Johnson is closer to signing a Brexit deal than F1 teams are to agreeing on the rules for 2021.
This also means that there is no Concorde Agreement in place yet for post-2020, and Marko says that Red Bull’s engine supplier Honda haven’t guaranteed their future in the sport.
“In qualifying we are still clearly behind, especially Ferrari,” he told Auto Motor und Sport.
“We lost eight tenths to them on the straights [in Japan]. But in the race we are about equal to Mercedes.
“They [Honda] are waiting until the new regulations are on the table, then they will analyse everything and decide.”
Marko went on to paint a bleak picture, stating that if engine costs are not reduced, then there will be “hardly anyone left” in Formula 1 when it comes to engine manufacturers.
“If it does not get cheaper, there will be hardly anyone left,” he warned.
