Ferrari have announced former Lotus technical director James Allison will join the team on September 1.
Allison, a highly-rated engineer in F1, left Lotus in May. The deal to join Ferrari, who have struggled for form in recent races, was done back in June, around the time of the Canadian Grand Prix.
In a statement, Ferrari said he will work alongside Pat Fry, who will take on a new position of director of engineering, with both men reporting directly to team boss Stefano Domenicali.
Allison and Fry previously worked together at Benetton in the early 1990s.
This will be Allison’s second stint with Ferrari as he worked for them between 2000-2005 when the team enjoyed considerable success with Michael Schumacher.
He then moved to Renault, which later became Lotus, when Fernando Alonso won the title in 2005 and 2006. He was made technical director in 2009.
