Ferrari gave the Halo 2 its first public track run on Friday morning at the British Grand Prix as work continues on refining the concept.

After extraction tests were completed in Austria last weekend, a planned run in first free practice had to be abandoned because of problems on the car – and the threat of bad weather.

However, Sebastian Vettel was able to complete an installation lap at Silverstone with the tweaked head protection design at the start of first free practice.

The Halo 2 is a lighter and reprofiled version of the original Halo that appeared at pre-season testing at Barcelona.

The shape has been changed slightly to ensure there is no risk of a driver hitting his head on the structure in the event of an accident, and the final version will be made of titanium to bring down the weight.

F1 technical directors met with the FIA ahead of the British Grand Prix to discuss the latest progress as work continues on introducing it for 2017.
