Formula One managing director Ross Brawn said on Monday he wanted departing Honda to help shape future engine rules that might encourage the Japanese manufacturer to return.
Honda announced this month that it will quit Formula One as an engine provider at the end of 2021 to focus on zero-emission technology.
The company, current supplier to Red Bull's two teams, left as a constructor in 2008 when it sold its team to then-boss Brawn who went on to win both the 2009 titles with Britain's Jenson Button and Mercedes engines.
