Alpine has continued its ongoing technical overhaul in its bid to become F1 title challengers within 100 races.
This year the team has parted company with Marcin Budkowski as executive director and four-time F1 champion Alain Prost who served as an advisor and non-executive director.
As part of a new organisation designed to maximise the team's performance that was initiated in November last year, Alpine has promoted Pat Fry to the role of chief technical officer and Matt Harman as technical director.
As CTO, Fry will primarily be responsible for all technical activities in Enstone, while Harman, who was previously engineering director, will oversee chassis technical direction in tandem with delivering performance and experiments to the track.
The moves are part of the vision of Renault Group CEO Luca de Meo and Alpine CEO Laurent Rossi as the team targets a title tilt within 100 races of its arrival into F1 last year.
Rossi said: “We are considerably strengthening Alpine F1 Team by having Pat and Matt at the helm of engineering in Enstone.
"Pat is one of the most experienced engineers in Formula 1, while Matt’s drive and expertise will prove critical in extracting the full potential of our race cars, thanks in particular to his unique expertise combining chassis and engine development.”
