Despite having launched their own proposal, Red Bull went on to try out rival Ferrari’s “Halo” cockpit protection system.

After launching the first halo design, Ferrari recently conducted tests with the so called “Halo 2” ahead of last weekend’s British Grand Prix, when Sebastian Vettel raised visibility concerns with the device.

Because Red Bull’s own idea, the aeroscreen, struggled during FIA crash tests, the Halo is thought to be the most likely system to be adopted by the FUA. Even so, Red Bull team principal Christian Horner continues to voice his concerns regarding this particular design.

“It’s an inelegant solution to the problem it is trying to deal with,” said Horner while discussing the halo after Sunday’s race at Silverstone. “I would prefer there to be more research time taken to do the job properly rather than rushing something through that may have other consequences.”

Horner went on to make himself abundantly clear on the matter, adding that he’s “not a big fan of the Halo and the limitations that it has. I certainly wouldn’t vote in favor at the moment.”

While the FIA remains determined to see it in action during the 2017 season, according to Autosport the design still has to be voted through by the teams at Strategy Group and F1 Commission levels.
