Pat Fry: Ferrari's engineering director leaves Formula 1 team

Pat Fry has worked in Formula 1 since 1987, with Benetton and McLaren among his former employers

Ferrari have parted company with two more major figures as their year of turmoil takes another turn.

Engineering director Pat Fry and chief designer Nikolas Tombazis have paid the price for years of sub-standard cars and are to leave the team.

They are the latest changes in 2014 that has seen Ferrari president Luca Di Montezemolo, two team principals and Fernando Alonso leave.

Alonso moved to McLaren having lost faith that Ferrari could win titles.

The Spanish two-time world champion, granted a release from his contract two years early at his request, has been replaced by four-time champion Sebastian Vettel, who will partner Finn Kimi Raikkonen in 2015.

Technical director James Allison will take over Fry's role running trackside engineering on an interim basis.

Fry had been at Ferrari since 2010, and in May 2011 was placed in overall charge of design following the sacking of their former technical director Aldo Costa.

Costa is now engineering director at Mercedes, where he was one of a team of senior figures who produced the car that dominated this year's world championship.

Fry was moved away from responsibility for the design of the car when Allison arrived at Maranello in September 2013.

Tombazis has been replaced by his former number two, Simone Resta.

The changes mark the latest stage in a major restructuring that has taken place at Ferrari since Fiat chief executive officer Sergio Marchionne took over from Di Montezemolo as president.

Marchionne sacked team principal Marco Mattiacci two days after the end of the season, only seven months after he had taken on the role.

Mattiacci was replaced by Maurizio Arrivabene, the former vice-president of global communications for Philip Morris - the tobacco giant and long-time sponsor of Ferrari.

Mattiacci, the former head of Ferrari North America, replaced Stefano Domenicali, who resigned in April following a poor start to the season.

Ferrari have not revealed why they dispensed with Mattiacci, who has left the company.

Former Mercedes technical director Bob Bell has been linked with a move to Ferrari in the future.
