"Getting a podium is the next thing on my list of achievements. We came very close in Singapore. It's not a secret that would probably be the biggest target I've got this year, to get on the podium. After that, we will set goals of what we think is realistic for where our car is but I expect to be racing the likes of Sauber and Williams," di Resta was quoted by Autosport.com Thursday.
"The likes of Mercedes, who we were racing at the end of last year, they have moved up a step by the looks of it. But never say never."
Di Resta also wants to improve his consistency this season.
"Consistency is probably one of the things I want to work on. That's equally the way we have built the car. I want to keep plugging away and keep coming away from each weekend saying we achieved everything we could have, or very close to it," added the 26-year-old Scot.
Di Resta's best finish ever was last year in Singapore, when he finished fourth.
