Toro Rosso have explained that a "steering issue" was to blame for Alexander Albon's spin on the second day of pre-season Formula 1 testing.
Albon exited the pits when the track went green to complete a shakedown lap, but as he approached Turn 4 on what was his first ever lap of the Toro Rosso STR14 (bar a filming day, which is conducted at slower speeds), the Thai driver span and beached his car in the gravel trap.
That caused an immediate red flag just a minute into the session as Albon's car was recovered back to the pitlane.
However speaking on Tuesday morning, Toro Rosso team boss Franz Tost laid the blame on an overnight change to the STR14's steering.
"It was a steering issue. We changed something from yesterday to today but it didn’t work out as we expected and therefore we changed once more to yesterday’s version," he explained to the official F1 broadcaster.
Tost said Albon's aim today was to get comfortable driving a new car and they would only focus on testing different specifications and set-ups next week.
"There are not so many test topics today as yesterday with Daniil [Kvyat]. We can’t test so many different specifications on the car, for him it’s important to drive to get experience, to learn the car to get familiar with the car.
"Next week is then another story. We will also test different set-ups with him next week. This week is more for him to do as many laps to get experience."
