Mike Elliott will take over from James Allison from July 1 as technical director of Formula One champions Mercedes, the team announced on Friday.
Allison will stand back from day-to-day management of technical operations and take on the newly created role of chief technical officer, working closely with the factories at Brackley and Brixworth.
"I firmly believe that people have a shelf life in senior roles in this sport, and I have chosen to step away from my role as technical director in order to pass on the baton at the right time for the organisation and myself," said Allison in a statement.
