The FIA has now confirmed that Red Bull's 'aeroscreen' concept is in the running to be introduced in Formula 1.
Daniel Ricciardo tested the windshield-style driver cockpit protection in the opening minutes of practice in Russia.
Earlier, the FIA's preferred solution for 2017 was the Mercedes-devised 'halo' concept that debuted on the Ferrari recently, but F1 race director Charlie Whiting has admitted that he actually likes the look of Red Bull's screen even more.
Auto Motor und Sport quoted him as saying that once all the tests are complete, the two solutions will be presented to the F1 Commission which will "decide what route we take".
