McLaren would be interested in developing its own Formula 1 engine from 2021 so long as the new regul𒀰ations are economically viable and attractive enough, according to executive director Zak Brown.

McLaren is nearing a final decision about its engine partner foꦦrℱ 2018, with a switch to Renault being considered as well as potentially extending the existing partnership with Honda despite its o🉐ngoing strugg𒅌les.

Brown confirmed on Friday at Monza ꦚthat any decision will be chiefly based on short-term thinking in a bid to improve McLaren’s on-track displays, with no long-term calls being made until the plans for shaking up the engine regulations in 2021 are made clear.

“We're interested to see what the new engine formula is in 2021, whether we'd consider doing our own engine, whether other people would come in under ne꧃w rules,” Brown said.

“I thinꦡk right now we've got to focus on the next three years. As soon as we get that figured out, we've got to look out.

“But I think the landscape in F🎉ormu🥀la 1 is going to change in a very positive way from 2021 onwards with budget caps and revenue redistribution and new engine rules.

“I think it's a little hard to take any decisions on '21 becaus𒆙e so many things will changeꦍ.”

When pressed about McLaren building its own power unit in-house, Brown stressed it would only be po♒ssible if it was cost-effective and a significant shift away from the current formula.

“For us to doℱ our own engine, that’s not something we’ve done before, so that would require good lead time and some expenditure that we would consider doing,” Brown said.

“W🧜e just need to have an understanding of the path forward, what are the rules and what are they going to cost.

“We certainly💮 wouldn’t be in a position to spend the hundreds of millions that it takes now to develop engines.

“So they’re going to have to change the engine formula for it to be something that is eღconomically viable for us♏.”
