Esteban Gutierrez says that the ill-handling nature of the Sauber C33 is hurting the team at this weekend's Canadian Grand Prix.
Sauber has failed to score a point so far in 2014 and their fortunes barely improved during practice, with Gutierrez in 16th place, one position ahead of team-mate Adrian Sutil.
"It’s been a tough day," said the Mexican. "We had some technical problems this morning, which is not ideal because we lost valuable track time. This afternoon we managed to solve the issues we had in the morning, but I’m still not completely happy with the car’s overall handling.
"But we have good information in order to put everything together for tomorrow, which is pretty important so that I can feel confident with the car and drive it to the limit. The whole driveability into the corners is quite tricky, and the car is snappy, which is obviously not ideal on a track that is quite slippery. In addition, it’s important to have a stable car when you want to drive on the kerbs."
Sutil simply said that Sauber has to make the best out of their current predicament.
"The main challenge in the morning was to get the tyres to work," he said.
"In the afternoon this was a bit easier. We tried different downforce levels.
"We still have to sort out some issues with the aerodynamics. Apart from that, there were no big surprises. We are where we are, and we have to make the best of it. The car is still not exactly where we want it to be, which is where it works the best, so we have some work left left to do for tomorrow."
