Toro Rosso Formula 1 drivers Pierre Gasly and Brendon Hartley are set to start Sunday’s United States Grand Prix from the back of the grid following a decision by Honda to change the power unit on both cars for the Austin weekend.
Pierre Gasly feels the time he spent racing in Japan last year is easing Honda's arrival at Toro Rosso ahead of the 2018 Formula 1 season, having enjoyed a successful first pre-season test in Barcelona last week.
Toro Rosso technical chief James Key is not concerned about no longer being Honda's exclusive Formula 1 power unit partner in 2019 should Red Bull strike an engine deal, believing it can only be a good thing for the B-team.
