F1 could delay its engine rules change beyond 2021

Formula One could delay the introduction of its new engine rules alterations beyond 2021 according to Ross Brawn.

Formula One had hoped that new engine regulations would perhaps attract more maufacturers, with the likes of Porsche, Aston Martin and Cosworth all considering joining the sport.

However, interest from these teams have now fallen away following delays of the rules being announced.

F1's managing director of motorsport, Ross Brawn has said that they might have to delay these rules, that were planned for 2021, even further - to attract more customers.

"We want to try and create a set of technical regulations on the engine which are appealing to new manufacturers coming in as well as consolidate our existing engine suppliers," Brawn said in an interview with the official Belgian Grand Prix programme.

"And I think we just need to think of our timing on that, whether 2021 is the right time to do that, or whether it's better to keep that powder dry until we can be certain that major regulation change will bring fresh blood into the sport."

Even if the main revamp is delayed even further, Brawn says that F1 will do all in its power to try and make proceedings fairer.

"My feeling is that there's still quite a lot we can do on the engine side in terms of sporting regulations such as limits on dyno test time, number of upgrades during a season, consistency of specification to all customer teams etc," Brawn added.

"On the engine, we need to decide if now is the time to have a revolution or an evolution."
