In late 1993 Postlethwaite returned to Tyrrell and invited Gascoyne to become deputy technical director responsible for the design of the team's 1994 car. Gascoyne accepted and remained with the team for four years, although lack of money severely limited his ability to produce a competitive racing car. When Ken Tyrrell announced his intention to sell to British American Tobacco, Gascoyne was forced to leave in the knowledge that the renamed British American Racing was to employ Malcolm Oastler as technical director.
