Sebastian Vettel ended the first day of a Pirelli wet weather tyre test at Fiorano early with a crash into the barriers.
The German was driving a modified Ferrari SF15-T 2015 car on the artificially dampened track to evaluate the progress Pirelli had made on their new wet tyres for the upcoming season, which are wider than the previous incarnation of the Cinturato rubber.
Further changes have also been made to the structure and compound in response to criticisms from drivers regarding a lack of confidence in the grip of the full wet tyre.
Thursday’s running was brought to an abrupt end when, on what is believed to be a warm-up lap, Vettel lost control of the car on the right hander following the bridge section and hit the barriers.
The damage was such that the remainder of the day’s planned programme was abandoned, with a decision yet to be made on whether the car will be ready to continue running on Friday.
Pirelli’s decision to take an extra wet weather test was prompted by a new regulation for 2017 which will see cars take a standing start following a safety car period, which means tyre temperature will have been built solely by the driver.
Antonio Giovinazzi is due to continue running on Friday, although he may now be sharing driving duties with Vettel.
