Toro Rosso suffered a double retirement at the European Grand Prix, making up for half of the non-finishers, as both Daniil Kvyat and Carlos Sainz were forced to retire their cars after just a handful of laps.
Having qualified 6th and 13th respectively, Toro Rosso had hoped for a good result on Sunday, but it wasn't to be as both cars were hit with rear-suspension problems which the team have yet to fully diagnose.
"Unfortunately we did not show a good performance today," explained team boss Franz Tost. "We didn’t finish with any of our two cars because of rear suspension problems.
"We will now have to wait to disassemble the cars to find out what the exact reason is, but it seems like the dampers got stuck, impeding the normal movement of the suspension.
"After performing well in qualifying yesterday, it’s a shame that Daniil’s race ended so early, as he could’ve put on a good show starting from sixth."
Kvyat isn't dwelling on the disappointment too much as he looks forward to the next race: "Quite a disappointing day, as I was only able to race for a few laps before retiring because of an issue with the rear suspension.
"The car became difficult to handle at the beginning of the race and even though we had quite a decent first lap, in the end we had to stop – it’s a real pity, but that’s life, this is part of racing," he added.
"We remain positive as the handling of the car has been very good this whole weekend, so the future looks promising and hopefully those enjoyable races will come soon.
"I will cancel today out of my mind and all we need to do is carry on working like we have done until yesterday, because everything was looking great before the race."
