GP3 driver Santino Ferrucci will continue as a Haas development driver for another year.
The 18-year-old American joined Haas last year and made his F1 debut at the in-season test at Silverstone last July. Alongside his second season in GP3 with French team DAMS, Ferrucci will continue to attend races and tests and take part in the team's simulator programme this year.
"We're very happy to have Santino back with us and look forward to his continuing development in GP3," said Guenther Steiner, team principal, Haas F1 Team. "We liked what we saw of him last year in our test at Silverstone and his maturity inside and outside of the car is impressive.
