Pirelli banking on two-stoppers

Date published: May 5 2015

Formula 1 is in for a two-stopping Spanish Grand Prix at the Barcelona circuit, that's the prediction of Pirelli's Paul Hembery.

Last season, the three drivers on the Spanish GP podium all opted for two-stop strategies and this year should be more of the same.

With the hard and medium tyres on offer, the biggest challenge the drivers will face is wear and degradation while Pirelli estimate the gap between the two compounds could be as much as 1.2seconds.

Hembery, the tyre company's motorsport director, said: "Spain is obviously one of the more familiar venues that we go to, as there has already been plenty of data gathered during testing. One of the things we have noticed so far is that this year Barcelona will once again be a front-limited circuit, from a tyre perspective.

"Last year, the increase in traction and torque from the cars meant that for the first time the race became a rear-limited event, with the useful life of the rear tyres dictating the pit stop strategy. Thanks to the improvements we made to the rear tyre construction for this year, we're back to Barcelona being a front-limited circuit again.

"However, we do not expect this to mean that there will necessarily be more pit stops this year: last year the majority of competitors used a two-stop strategy and that will probably be the case again.

"The biggest unknown factor will be the weather: in the past we have seen some very hot weather in Barcelona, but it isn’t always guaranteed.

"The start of the European season traditionally means that many teams bring important upgrades, and it will be very interesting to see how these interact with our 2015 tyres."
