Sauber driver Nico Hulkenberg says that his team should be able to aim for a top ten position in qualifying tomorrow.
Hulkenberg was tenth in second practice ahead of the Australian Grand Prix.
"Overall it was a challenging day," he said. "On the first day there are always a few things you need to work on and improve. I think we still have some homework to do."
"Free Practice two was quite difficult for me because of traffic. I think we can still improve our time. We collected a lot of data for the tyres and if we do our homework well we should be able to aim at the top ten qualifying tomorrow."
Esteban Gutierrez added that both he and the team need to find a bit more speed.
"It was a very productive day. The tyres are getting better, and not as critical as in Barcelona. As a team we need to find more speed, and that means me as a driver as well. I’ve improved from free practice one to free practice two. Now I will focus on improving for qualifying tomorrow," he said.
