Former Mercedes technical director Bob Bell has returned to the newly-created Renault Sport Formula 1 team as chief technical officer.
After recently splitting from Manor Marussia as technical consultant after just six months, the Northern Irishman steps into the senior technical role at the Enstone-based squad which has revealed an all-new line-up after transforming from its Lotus F1 team guise.
Bell was officially announced as Renault's chief technical officer at the team's launch in Paris alongside the unveiling of new drivers Kevin Magnussen, Jolyon Palmer, new third and reserve driver Esteban Ocon and the Renault RS16 challenger.
Bell will manage Nick Chester who becomes chassis technical director and Remi Taffin who steps up engine technical director. Renault also confirmed the team's F1 chassis will be developed at the team's Enstone factory while the Renault power unit development will continue at Viry-Chatillon.
Bell began life in Formula 1 with McLaren as an aerodynamicist in 1982 before being promoted to Head of Research and Development in 1987.
After spells at Benetton and Jordan, Bell joined Renault in 2001 as deputy technical director before being promoted to the head role two years later, leading the team to the consecutive drivers' and manufacturers' F1 world championship in 2005 and 2006.
Bell then rose to Renault F1 team principal in 2009 before departing to Mercedes as technical director in 2011 and officially left the team at the end of 2014..
