Manor Racing has continued to bolster its set-up after confirming the signing of Pat Fry as an engineering consultant.
Fry has worked for Benetton, McLaren and most recently Ferrari, which he departed amid the mass exits in 2014.
Manor has been restructuring across recent months with Dave Ryan and Nikolas Tombazis both joining the fray.
"We are extremely fortunate to have Pat on board to help us hit the ground running with our exciting new technical package," said Ryan, the outfit's Racing Director.
"The aim is to bring performance to the car with effect from the Barcelona tests, then translate that to the race track in Melbourne, to ensure we make the strongest possible start to 2016 and have a good basis for development in the early part of the season."
Manor will debut a new car this year, fitted with Mercedes power units, having spent 2015 using a modified version of its 2014 car and year-old Ferrari engines.
