Feb.17 (GMM) Mike Gascoyne has handed over day-to-day control of the Caterham team's technical operations.
The former Lotus outfit announced that Briton Gascoyne - a founding member of the Tony Fernandes-led team and a long-term prominent figure in the paddock - has become chief technical officer of the whole Caterham Group.
That group now involves a GP2 team as well as the niche Caterham road car company, which was acquired by Malaysian millionaire Fernandes last year to solve the Lotus naming dispute.
The news means Mark Smith will "lead the F1 team's technical division day to day and will increase his presence at races", a media statement read.
Caterham said Gascoyne, formerly with Renault and Toyota, "will continue to attend races", "adding his wealth of experience and knowledge to the team when it is required."
Gascoyne clarified on Twitter that he will be at "most" Grands Prix.
"Mark Smith is exactly the right person to step up to the broader role he will now be taking on in the F1 team," the statement quoted him as saying.
