Renault is expecting less caution and more aggression from Jolyon Palmer in his maiden Formula 1 season this year.
In 2015, Palmer dovetailed his GP2 commitments with Friday testing duties for Lotus, running in eight free-practice sessions on Grand Prix weekends.
The French manufacturer's trackside operations director Alan Permane has no doubts about Palmer's ability to perform consistently at the highest level, but he does believe the 25-year-old British driver, who will be paired with Kevin Magnussen at Renault this season, needs to show more aggression behind the wheel.
"Jolyon didn't have too much of a chance to shine last year," Permane told Autosport.
"He was very unlucky with the weather, missing a lot of first practice running. He still did well, but now I would like to see him do even more as he was possibly cautious, I don't know.
"He is not the sort of driver who will go out and spin at every corner to see where the limits of the car are, and stuff like that.
"Just to be clear, I have no doubt in him or his ability, or anything like that, and just talking to him you can see he is a bright guy.
"Seeing what he did in GP2, how quick he was, how well he raced, and knowing how he talks and thinks about race strategy and stuff, just how his mind works, I'm sure he is going to be fine."
