Toro Rosso have not yet revealed why Sébastien Buemi’s car came to a half in the final 20 minutes of Valencia testing on Wednesday, with the Swiss driver having stopped his new STR6 just past the pit entrance on the Ricardo Tormo start/finish straight.
When contacted by GPUpdate.net on Wednesday afternoon, the team was unable to reveal the reason for the stoppage and its daily press release also failed to explain a cause.
“This afternoon was my first time in the car and it felt good to be driving again after the winter break,” Buemi commented. “I ran for about three hours managing 46 laps, which is quite encouraging for a first day.
“It is going to be an interesting evening studying all the data, as so much is new to us and we also need to understand, as soon as possible, how the car behaves; so tomorrow will be a case of carrying on down this route.”
