Marcus Ericsson has said he has worked on improving his qualifying form in 2016.
The Swede will stay at Sauber for a third successive season in 2017, and believes the groundwork he has laid in 2016 will serve him well going forward.
"I've been focusing on qualifying and that system has been working very good for me," he told Autosport. "This year I really found a way to get a reference of what I need to be fast.
"I need a stable rear end going into corners so I can trust that and then I can get the confidence to carry the speed going into the exits of the corners,"£ he added. "That was something that wasn't maybe 100% clear for me before."
"These types of details sound small but in the end they make a big difference."
