Pierre Gasly will miss the United States Grand Prix in order to compete for the Japanese Super Formula title.
The Frenchman remains in the championship hunt as he is just half a point away from championship leader Hiroaki Ishiura with two races remaining at the final round in Suzuka.
Red Bull’s motorsport advisor Helmut Marko stated Gasly would race for Toro Rosso in Austin, however, the option was left open for the 21-year old as Honda boss Masashi Yamamoto did want Gasly to push forward with his Formula 1 challenge and concede the Super Formula title to rivals Toyota.
The Honda boss told Autosport last week: “We want him to race there but if there is anybody who can drive instead of Gasly in Austin, we’re happy to have him in Super Formula. We are not pushing for him to race in Super Formula.
“Of course it is important for Honda to win the Super Formula title in Japan but we think the priority is having him in F1.”
It is unknown whether Gasly will drive for Toro Rosso again in 2017 but with Carlos Sainz’s early departure from the team to replace Jolyon Palmer at Renault, he looks set to see out the final three races of the season with the Red Bull junior team.
Daniil Kvyat is set to return in Austin after being cast to the sidelines due to Gasly’s surprise promotion to a race seat, however, options for a possible team-mate to the Russian remain very limited.
