It was reported yesterday that Pirelli will be supplying the teams with their P Zero Purple ultrasoft tyres for the first time at Spa-Francorchamps, together with the P Zero Red supersoft and P Zero Yellow soft.
These are the three softest tyres in the range, selected together for the sixth time so far this year. But one famous variable in Spa is the weather, so there's also a strong chance of seeing the Cinturato Green intermediate or Cinturato Blue full wet at some point during the weekend.
Spa is a favourite of nearly all the drivers, incorporating classic corners such as Eau Rouge and Pouhon that make it a real rollercoaster ride, as well as a true test of bravery.
It is also the longest circuit of the year at 7.004 kilometres and it's geographical layout means it can be raining on one part of the track but dry on another. Elevation changes and compressions generate forces on tyres from all directions and compromise on set-up is needed to provide downforce in corners without causing too much drag.
“Pirelli was racing at Spa for the 24 Hours last month, which showcased everything this circuit is famous for: changeable weather, unpredictable competition, and heavy demands on the tyres,” said Mario Isola, head of car racing at Pirelli.
“Now that we are bringing the ultrasoft tyre there for Formula 1, we would expect those demands to increase further with the latest generation of cars: two stops would appear to be a likely strategy but we will know more after the first free practice sessions."
"Working out the optimal race strategy is especially tricky at Spa as it has to be flexible: the possibility of rain, safety cars, or even a red flag – as we saw last year – means that teams often have to react to changing circumstances rather than follow a fixed plan”.
