Lotus are reportedly looking to drop Cosworth in favour of Renault power for next year's Championship.
The Lotus name returned to Formula One this season, powered by Cosworth engines, and have proven to be the more competitive of the three new outfits.
But in a bid to move further up the grid, the team is already considering swapping to Renault power.
According to the BBC, team boss Tony Fernandes and tech director Mike Gascoyne held talks with Renault at Silverstone on Sunday morning.
However, when asked about the situation, Gascoyne refused to comment, saying: "We have a contract with Cosworth and we're discussing with them ways to work together in the future."
