Team Lotus will use Renault power and Red Bull's rear end and KERS system in 2012 and 2013, it was announced before the Singapore Grand Prix on Sunday.
The collaboration - excluding the KERS element - was already in place for 2011 and 2012 and so the one-year extension will take Team Lotus' technical solution through to the end of the V8 era.
Team Lotus also said it aims to stay with Red Bull and Renault "when the new engine regulations come into force" in 2014.
"This year we have established solid foundations with Team Lotus and this latest agreement consolidates the relationship that we look forward to continuing for many seasons to come," said Renault Sport F1's Jean-Francois Caubet.
