With Valtteri Bottas’s pace-setting 1:19.705 two seconds up on last year’s Barcelona pole and five seconds faster than the time set in 2015, Pirelli have declared that the “objective has been met.”
This season Formula 1 wanted the cars to be up to five seconds per lap faster than in 2016, and although they aren’t there yet, they are closing in on the target.
Bottas topped this week’s timesheets at the Circuit de Catalunya as he posted a 1:19.705 on the ultrasoft tyres.
That put him 2.295s up on his team-mate Lewis Hamilton’s 2016 pole position time, and 4.976s faster than Nico Rosberg’s P1 time in 2015.
Mario Isola, Pirelli Racing Manager, said: “We’re satisfied with the results of these four days. From what we can see up to now, the new product is in line with our expectations.
“For the 2017 season, the sport asked us to develop tyres with less degradation, which allow drivers to push to the maximum. That’s what we’ve seen during these four days of testing so far, and what we’ll continue to see in the second four-day session next week.
“During the first session, the lap times have already been lowered considerably. The target was for lap times that were five seconds faster compared to Barcelona in 2015.
“Yesterday, Valtteri Bottas set a best time of 1m19.705s on ultrasoft tyres. Considering that the pole time in 2015 at Barcelona was 1m24.681s, I would say that this objective has been met.”
Pirelli switched over to the wet and intermediate tyres for the fourth and final day with the trucks artificially wetting the circuit.
“Today, we also saw the new wet weather tyres on track for the first time on the 2017 cars,” Isola added.
“The combination of new dimensions and a new tread pattern means that the water expulsion capacity of the Cinturato Blue full wet tyre has gone up from 65 to 85 litres of water per second, per tyre, at 300kph. The Cinturato Green intermediate also has an increase: from 25 to 30 litres of water per second dispersed.
“We’ve now collected plenty more data for our engineers to analyse ahead of the next test session that takes place from March 7-10, again in Barcelona.”
