Renault's chief technical officer Bob Bell will take on an advisory role at the team after expressing a desire to take a step back from front-line work in Formula One.
Bell joined Renault in 2016 after a brief spell at Manor in 2015 and four years at Mercedes between 2010 and 2014. He was the most senior member of the Renault technical team, overseeing both the engine department in Viry-Chatillon and the chassis side in Enstone, but will now take responsibility for developing technical collaborations between the team and third parties.
Managing director of Renault Sport Racing Cyril Abiteboul paid tribute to Bell's work at the team.
