Despite running the halo cockpit protector at the in-season F1 test at Silverstone, Christian Horner says Red Bull would vote against the introduction of the device for 2017 and says it is an 'inelegant solution'.

Red Bull have become the first team other than Ferrari to test the revised halo protection unit with Pierre Gasly completing an installation lap with it on the opening day of the second in-season test after the British Grand Prix.

Speaking on Sunday after the race at Silverstone, Horner says Red Bull are against the device being in the 2017 rules and sees the design as a rushed and inelegant fix to protect drivers' heads inside the car cockpit.

"Personally I am not a big fan of the halo. I think it is inelegant solution to the problem that it is trying to deal with," Horner said. "I'd prefer there to be more research time taken to do the job properly, rather than rushing something through that may have other consequences.

"So, I am not a big fan of the halo and the limitations that it has. I certainly wouldn't vote in favour of it at the moment."

Sebastian Vettel debuted the 'halo 2' redesign in an installation lap during free practice one at the British Grand Prix after Ferrari's first concept came under criticism when it first appeared during winter testing.

The FIA is exploring the option of introducing a cockpit protection device for 2017 and is undergoing testing to determine whether it would be ready.

Red Bull Racing has developed an alternative to the controversial halo prepared by Ferrari with its own aeroscreen which made its debut on Daniel Ricciardo's car in free practice one at the Russian Grand Prix.

However, after the FIA remained uncertain about the aeroscreen's effectiveness - despite Red Bull releasing videos of the device during a high-speed impact test - it has backed the halo device to be implemented.
