2016 F1 season teams will be allowed to select from three compounds at each grand prix weekend.
Formula One world on last Tuesday got its first good look at Pirelli’s new ‘ultra soft’ tyre.
The best time posted by Sebastian Vettel was particularly noteworthy, as the Ferrari driver went almost two seconds faster than Nico Rosberg’s 2015 pole.
Red Bull’s Daniel Ricciardo also impressed with the purple-coloured tyre, telling the Finnish newspaper Turun Sanomat in Barcelona: “They are grippier and different in nature.
“They seem like fun,” he added.
Recently F1 tyre provider Pirelli confirms the new ultra-soft compound will make its first appearance at round seven, the Canadian Grand Prix.
There are, however, some guidelines such as each driver must save one set of the softest compound – for Canadia that will be the ultra-soft – to be used in Q3.
The other compounds available for the Montreal race will be the softs and the super-softs.
