Bell enjoyed three separate stints with the team through its Benetton and Renault eras, starting in 1997.
He took a step back to an advisory role in 2018 and subsequently – like several technical veterans at other teams – he moved away from an F1 involvement to work part-time for Alpine Labs, an organisation founded to explore the use of racing technology in other fields.
Although no longer directly involved with F1 activities Bell remained something of a talismanic figure in the camp, and was a tangible link to past successes.
His daughter Katy works for the team as an electronics systems engineer, attending some races.
Ulsterman Bell first made his name as an aerodynamicist at McLaren from 1982 and then in the Ayrton Senna era, and was part of the team that designed the dominant MP4/4 of 1988.
He moved to Benetton in 1997, before heading to Jordan for a spell as head of vehicle dynamics – including the 1999 season when the team finished third in the world championship – before returning to Enstone and the renamed Renault team in 2001.
He was technical director during Fernando Alonso’s successful title campaigns in 2005 and 2006.
