Jean Todt has dismissed rumours that the controversial Halo concept will be scrapped ahead of the 2018 season.
In a garage test in Abu Dhabi, Valtteri Bottas failed to get out of a Halo-equipped Mercedes within the prescribed seven seconds.
Amid existing concerns about the aesthetics of the cockpit protection solution, and the fact the extra weight will make next year's cars slower, it all triggered rumours that Halo could be scrapped at the 11th hour.
"There is no way back," FIA president Todt is quoted as saying by Speed Week.
"The Halo is coming and it is staying. Why? Because it offers incredible value for safety.
"I am fascinated by what has been written about it. The Halo is simply part of the natural continuity of Formula 1.
"Of course it does not have to be the final word either. If we find a better solution then we will introduce it."
Bottas won yesterday's season-ending Abu Dhabi Grand Prix, with Lewis Hamilton and Sebastian Vettel rounding out the podium.
