Integrating the controversial Halo device onto next year's cars is proving to be a big challenge for F1 teams, despite the fact it is likely to have a "minor aerodynamic effect" on performance.
Earlier this year the FIA confirmed the cockpit protection device will be introduced for 2018, one of the most significant changes to the overall look of a Formula One car in the sport's history. The Halo is designed to reduce the risk of serious head injuries by offering drivers extra frontal protection against flying debris.
The Halo has been tested by various teams at the races since the announcement was made in July but continues to divide opinion among drivers and fans.
