Romain Grosjean has ruled out early podium finishes for his Lotus team, and says scoring points will be the main target in the first races.
The Enstone-based team endured a dismal 2014 season, with Grosjean managing just eight points and teammate Pastor Maldonado two.
But both drivers have been encouraged by the progress made with the Mercedes-powered E23 during winter testing.
Despite that, Grosjean is setting modest targets, at least for the first part of the season.
"It's too early to talk about podiums," Grosjean told RMC Sport. "I think you can say now that I will be reaching Q3 at times.
"Being in the top ten, scoring points, that is the primary objective.
"Then it will be the top five and then we can dream about the podium, but you have to climb the steps one after the other."
Lotus' decline last year was linked to the significant personnel cuts after 2013, but Grosjean said the team has now corrected that with recruitment to "important positions" in the last six months.
"Between 2013 and 2014 there were a lot of departures, but people that have since arrived have become accustomed to their roles and are now offering us the best solutions."
