Cool temperatures, fog and rain has been blamed for holding up Pirelli's final private test with Mercedes on the 2017 slick tyres at Circuit de Catalunya with the Italian manufacturer looking to make up lost time in Abu Dhabi.
After overnight rain factory Mercedes driver Pascal Wehrlein, who filled in for Lewis Hamilton who pulled out of testing duties with a foot injury, could only manage 31 laps to add to the 60 laps Nico Rosberg managed on the first day of the slick 2017 tyre test at Barcelona using the 2015 Mercedes mule car.
Pirelli confirmed running was hampered by cold conditions – with track temperatures reaching just 15 degrees centigrade – while persistent rain and fog also restrained Wehrlein's track time on the wider compounds on 2017 sizes.
Paul Hembery, Pirelli motorsport director, is confident the Italian tyre manufacturer can pick up on lost time in Abu Dhabi with a three-day slick tyre test with Red Bull on the 14-16 October.

“Obviously the weather hindered progress to some extent both today and yesterday, as is not entirely unexpected at this time of year in Europe,” Hembery said. “The same can apply to the early part of next year, which is why we are in favour of some guaranteed warm weather testing in 2017, before the season gets underway.”
