AlphaTauri say they will have a major review of their performance at the Austrian Grand Prix, in which both drivers finished well outside the points.
Pierre Gasly and Yuki Tsunoda ended the Spielberg race down in 15th and 16th places respectively, and with AlphaTauri now having not scored points in the last three Grands Prix, there were long faces in the team after Sunday's struggles.
"It's been really tough, that was a long race," lamented Tsunoda.
"I had no pace at all this weekend and really struggled with the car sliding all over the place.
"We need to go away and look at what the issue may be, as we've not seen anything in the data that explains why this weekend has been so difficult.
"I gave it my everything and there wasn't much more I could've done, but this has been the hardest race weekend we've had so far this year."

A big review incoming at AlphaTauri
AlphaTauri's Technical Director, Jody Egginton, was equally downbeat, and mentioned the need for a major review at the team's Faenza headquarters ahead of F1's next action at the French Grand Prix on 24 July.
"A very difficult race for us today, as we weren't able to make any progress," said Egginton.
"We've been on the backfoot all day and unfortunately have come away with nothing. We've got a lot to review back at base.
"Now our focus is to get our updates to the car ready for the French Grand Prix and get ourselves back into the midfield fight."
