Gene Haas says it would make little business sense for his team to hand a full-time race seat to a Ferrari junior in future, despite an extensive engine and technical partnership with the Italian company.
Haas is the only Ferrari customer using up-to-date engines this year and receives as many parts from the Prancing Horse as the regulations allow. Ferrari junior Antonio Giovinazzi is set to complete seven FP1 sessions with Haas this year, though the team has already confirmed it will retain Romain Grosjean and Kevin Magnussen in 2018.
Sauber recently confirmed a deal for up-to-date Ferrari engines for next year and is expected to take Giovinazzi's fellow Ferrari junior and current Formula 2 points leader Charles Leclerc in a 2018 race seat, though it has denied suggestions it will become a 'Ferrari B' team.
