Brawn: F1 will have cheaper, simpler, louder engines but...

The current F1 hybrid era has been a costly exercise with Mercedes and Ferrari powering three teams apiece, with Honda and Renault each supplying two teams.

Despite the annual Audi/Porsche/VW rumours, no manufacturers are interested in investing the hundreds of millions it will take to develop such an engine package and then compete with teams that have used the technology for nearly a decade.

Brawn admitted in an interview with Motorsport Network, "In that case, I was perhaps a bit more ambitious in terms of the changes that could have been made, but when the arguments were presented they were well presented, the models were well presented, and the examples were given."

"I think we will have cheaper, simpler, louder, it's just a question of degree. There's a very strong argument that we have four reasonably settled suppliers in F1. Whilst there are people looking at coming in, they weren't as committed so, therefore, let's consolidate what we have."

"The MGU-H was a big thing. I think if a manufacturer is coming in or not coming in just because it had or hasn't got an MGU-H it seems a bit fickle."

"The engine is a tricky one, more so perhaps than the car you're sensitive to outside suppliers, you're sensitive to engine suppliers. We don't want to lose a team, but if we lose a team then hopefully F1 is attractive enough to find replacements.

"If we lose an engine then anyone stepping in has a massive programme to step in and fill their place. And if we lose an engine it impacts two or three teams. I think it was correct to push hard to see where we can get to.

"There will be some changes that you'll see - we're not going to talk about them now - which will come out in the next few months which I think definitely are strongly in the right direction," reasoned Brawn.
