Red Bull has become the latest team to conduct tests on the halo head protection device following trials by Ferrari at the British and Austrian GPs.
Reserve driver Pierre Gasly wore special eye-tracking glasses to record the movement of his line of sight whilst completing two installation laps with the titanium frame mounted on his car.
The data will be used to determine whether or not changes need to be made to the design to improve visibility from the cockpit.
After finishing the session, Gasly – who drives in the GP2 championship alongside his F1 duties – said he was “a bit surprised” by the experience: “From the inside of the car it doesn’t change much. You see something on top of the helmet and also the vision when you look straight you kind of see this triangle on top. It’s different.”
However, the 20-year-old Frenchman isn’t convinced that the halo is the right way for the sport to go, saying: “I don’t really like it, because for me F1 always looked like open cockpit. We’ll see.”
His comments add to a growing sense that halos might not be introduced in 2017 after all, with Ferrari driver Sebastian Vettel, Red Bull boss Christian Horner and Haas principal Gunther Steiner voicing their concerns in recent days.
The F1 Strategy Group and F1 Commission could vote to postpone the device’s planned introduction at the beginning of next season, although this could be countered by the FIA on safety grounds.
