Red Bull is pressing on with the development of its alternative to the FIA-preferred ’halo’ concept for cockpit protection for 2017.
F1’s governing body has played down the notion that Red Bull’s open-topped, bulletproof-windshield system might get the green light.
But Red Bull chief Christian Horner said the concept will be tested anyway next week, when a wheel is fired at it while attached to a static structure.
"If that goes ok, we may put it on one car very briefly in Sochi," he told British television Sky, referring to the forthcoming Russian grand prix weekend.
