Sauber: No excuses for not scoring in every race given car's potential

The Swiss team's C31 has proved to be quick at most circuits, but Sergio Perez and Kamui Kobayashi have struggled at times to capitalise on that performance - either through poor form in qualifying or getting involved in incidents in the race.

And although Sauber CEO Monisha Kaltenborn says there is little point ruing what might have been in previous races, she suggests that there is no reason why the team should not deliver on all occasions going forward.

"We have failed to score points this season several times and for a variety of reasons," she said. "In hindsight it doesn't help to pine for those points, as now we have to move forward.

"The Sauber C31 has proved to be quick on all types of circuits. Plus we've got two strong drivers - Sergio has been on the podium twice this year, and Kamui has been able to shine with a fourth in qualifying and a fifth in a race. Both have a fastest race lap to their names.

"We have everything it takes to wind up the first half of the season in a positive way, and that's our aim for Hockenheim."

Sauber introduced a car update at the British Grand Prix, but the team does not know how much of an improvement it is because bad weather at Silverstone hampered running.

Kobayashi said: "We are not totally sure how the updates we took to Silverstone work, as we haven't really been able to confirm these in practice in dry conditions. Maybe we need to do some more fine-tuning on these, so it will be interesting to see how this happens in Hockenheim."
