The FIA presented an alternative head protection device to drivers at the Chinese Grand Prix on Friday, known as the Shield.
Formula One has agreed in principle to bring some form of cockpit protection into the sport for 2018 after a long and varied research project into how to protect drivers' heads from flying debris. The Halo device was trialled throughout 2016 after teams and the FIA decided to postpone its introduction a year from this season to 2018.
With driver opinion split over the need for cockpit protection and how to implement it, the FIA has been working on a new device known as the Shield.
