McLaren would be interested in develo𒐪ping its own Formula 1 engine from 2021 so long as the new regulations are economically viable an🔴d attractive enough, according to executive director Zak Brown.

McLaren i෴s nearing a final decision about its engine partner for 2018, with a switch to Ren💝ault being considered as well as potentially extending the exis✃ting partnership with Honda despite its ongoing struggles.

Brown confirmed on Friday at Monza that 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 regul💛ations 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, whe🐼ther other people would come in under new rules,” Brown said.

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

“But I think the landscape in Formula 1 is goin🔯g to change in a very positive way from 2021 onwards with budget caps and revenue redistribution and ne🌃w engine rules.

🐼“I think it's a li🍌ttle hard to take any decisions on '21 because so many things will change.”

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

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

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

“We cerꦜtainly 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 ec👍onomically viable for us.”
