ROME - The clear-out at Maranello continues.
Ferrari have parted company with chief designer Nikolas Tombazis and engineering director Pat Fry, two of the men responsible for designing this year's car, as the team endured their first season without a win since 1993.
"Nikolas Tombazis and Pat Fry will be leaving the Scuderia," the Formula One outfit said on Tuesday, while handing structural control to technical director James Allison.
"James Allison...will be responsible for all technical aspects of delivering drivers Kimi Raikkonen and Sebastian Vettel, as well as newly appointed test driver and third driver Esteban Gutierrez, with the most competitive Formula One car possible."
It has been a period of upheaval at Ferrari, after Marco Mattiacci's brief reign as team principal ended at the end of last month.
The troubled Fiat-owned outfit replaced him with Maurizio Arrivabene, the team's third boss in nine months.
Long-serving president Luca di Montezemolo, a link with the team's late founder Enzo, also left Ferrari last month.
He has been replaced by Fiat Chrysler chief executive Sergio Marchionne.
The glamour team ended the season in Abu Dhabi without a single race win and the conclusion of the campaign also saw the departure of two-time world champion Fernando Alonso.
Germany's four-time champion Vettel has been signed from Red Bull as the Spaniard's replacement.
Mexican Gutierrez, 23, was signed by the 16-time F1 constructors' champions on Monday.
He spent two years at Sauber after making his grand prix debut in Australia last year, and will provide back-up to Vettel and Raikkonen, winners of a combined five world drivers' titles.
Gutierrez, who failed to win any points at Ferrari-powered Sauber last season, said: "It is an honour to become part of the Ferrari family, a team with such an exceptional history."
