The Haas F1 Team has confirmed that teenage hopeful Santino Ferrucci will run with the US outfit next week at the Hungaroring.
The 19-year-old, who is racing this season in the GP3 Series, will be entrusted with the team's VF-17 car on both days of the in-season test in Budapest.
Ferrucci enjoyed his maiden F1 run with Haas last year at Silverstone.
As part of its young driver development programme, Haas will also run Antonio Giovinazzi in Friday's first free practice session, the Ferrari reserve driver continuing his scheduled FP1 apprenticeship with Haas.
Haas founder Gene Haas confirmed last week that Romain Grosjean and Kevin Magnussen have both been retained for 2018.
