Both Scuderia Toro Rosso drivers endured difficult days at the Circuit de Barcelona-Catalunya on Wednesday as both suffered drivetrain issues on their STR12’s.
Daniil Kvyat was in the car for the morning session before handing over to his team-mate Carlos Sainz Jr, but the Russian completed just 31 laps and the Spaniard 32 laps as the problems with their drivetrains materialised.
“A bit of a frustrating morning for me today because we lost some valuable track time due to a drivetrain issue,” said Kvyat, who finished bottom of the time sheets on Wednesday.
“It’s a shame for myself and the team, because we should be using the time to add laps to our tally… But, on a positive note, when the car is running it feels good and there’s always something positive found by the engineers and myself.
“My feeling with the car is also improving lap after lap. We just need to keep our heads down and continue to work as hard as we are already doing.”
Team-mate Sainz finished eleventh fastest of the thirteen drivers that took to the track on Wednesday but saw his session end when he stopped on track at turn four to cause a red flag.
“How annoying to have to finish the session early!” said Sainz. “Doing only half a day today, we were looking to maximize it, get into a good rhythm and add plenty of mileage to the car.
“Unfortunately, we suffered a drivetrain failure half way through the afternoon, which meant we had to stop and not run any more today. It’s frustrating, but this is what happens sometimes during testing.
“We need to stay positive and make a big push tomorrow and during next week’s test.”
