Incumbent Formula 1 engine suppliers will be obliged to share certain componentry with new entrants in the wake of the winding back of 2021 regulation changes.
F1 managing director of motorsport Ross Brawn hopes that the arrangement will encourage additional manufacturers to join the championship after attempts to dramatically change engine rules from 2021 did not come to fruition.
“The drawbridge has been pulled up and the existing suppliers don’t want anyone else to come in,” said Brawn in an interview on F1’s official website.
“We have found a compromise. There are regulations coming out which would mean new entrants will get support from existing entrants. There will be components and technology which will have to be shared if it is requested.
“It is not quite such a radical change that we were proposing, but still quite a good step in the right direction and there are some nice changes to the way the driver has to manage the engine, which I think goes a long way in the sporting direction.
“There has been a recognition from the existing manufacturers that they can’t shut the door behind them.
“If we start to get serious interest from another manufacturer or supplier, they have to cooperate to find ways of helping that manufacturer come into F1.”
Mercedes, Ferrari, Renault, and Honda currently supply teams on the grid, while Aston Martin, Cosworth, and Porsche had looked at joining the championship in 2021.
