Scuderia Toro Rosso principal Franz Tost has hit out at the decision to bring Formula 1 pre-season testing back to Europe, claiming much of the feedback the team is logging won't be relevant for the season going forward.

Formula 1 marked the new era of F1 in 2014 by spitting its testing schedule between four days in Jerez and eight days in Bahrain, but opted to stay in Europe for 2015, with the Circuit de Catalunya replacing Sakhir on the pre-season schedule.

However, though weather conditions in Barcelona have been fairly good, albeit cold and - particularly on the final day - windy, the move has drawn the ire of Tost, who says it is difficult for teams to get representative data when the ambient temperatures of Spain in February are far lower than they would be during the course of a race season held predominantly during summer months.

"I have to say it's really difficult to estimate our own performance or the other teams', as track and ambient temperatures are far too low. At the races where we expect much higher ones, the tyre management will be completely different.

"Personally, I don't like the tests in February here in Europe, as you don't get the feedback on all the technical topics you need to be well prepared for the start of the season. Last year's test in Bahrain was much more useful."

The decision to test exclusively in Spain is believed to have been motivated by a desire to reduce logistical costs, but also to entice spectators to attend, particularly during weekend test days.

Despite Tost's reservations, Toro Rosso enjoyed a largely positive four days with its rookie pairing of Max Verstappen and Carlos Sainz Jr at the wheel, notching up 411 laps.

Four more days of testing begin on 26th February before the season gets underway in Australia on 15th March.
