Motor racing-Bell follows Alpine F1 exodus and moves to Aston Martin

(Reuters) - Former Renault technical director Bob Bell has left the Alpine Formula One team, where he had an advisory role, and joined rivals Aston Martin as technical executive director.

The move reunites the 65-year-old with Spaniard Fernando Alonso, who won two world championships with Renault in 2005 and 2006 and joined Aston Martin from Renault-owned Alpine last season.
