High-degradation Pirellis causing biggest headache for Formula One’s least-experienced driver.
Toro Rosso's teenaged sensation Max Verstappen has admitted that learning about the control Pirelli tyres, and their high-degradation nature, has been the hardest thing to adapt to in Formula One so far.
F1 rookie Verstappen, who stated that he was used to driving "flat-out" from start to finish in F3 European Championship races, said during testing in Barcelona: "Tyres are quite difficult, that is where I have to pay a lot of attention.
"In every aspect I can still improve. I'm enjoying every lap."
On the subject of development of the Renault-powered STR10, he added: "We are learning in every way, not one particular point is difficult, because we've just started."
Race distance completed with ease
The 17-year old claimed he was having no issues with the physical side of driving the much more powerful cars, after setting the sixth-fastest time on day one.
"I feel quite happy about it," he said after completing 94 laps on the opening day at Barcelona.
"The morning was not like we wanted but we were able to do a lot of laps in the afternoon, I think reliability is getting better all the time.
"It's good to do some many laps in one go, to see where your weaknesses are and where you're good. I was feeling quite well.
"This track is quite hard on your neck, so it's good to do race simulations here. It's just understanding the car more and more."
