Sauber are hoping to finish with both cars in the top ten at the Spanish Grand Prix – a feat they are yet to achieve after a disappointing start to the season.
The Swiss team will introduce its latest upgrade package at the race, which includes a new rear-wing. Head of track engineering Tom McCullough hopes the wing will resolve some of the rear stability.
“We have some further aero updates, including a modified rear wing, and we will be evaluating these during Friday practice,” he said.
“Qualifying is particularly important here as overtaking can be difficult in the race. Our target for the race is to finish with both cars in the points.”
At present, Nico Hulkenberg has scored five points in four races, whilst Esteban Gutierrez is yet to score.
