Caterham reserve driver Alexander Rossi will test for the team in first practice at the Canadian Grand Prix next month.
Rossi was due to drive in Bahrain but was called up to Caterham's GP2 team, postponing his run.
"The weekends that I'm not doing GP2 I'll be looking to be drive the F1 car in Friday practice sessions and that will start in Montreal, he told ESPN. "Beyond that I'll be doing at least one more, and possibly others, but it's hard to say exactly what will happen because in F1 you never know for certain until you're in the car. Whatever happens, the more time you can spend in an F1 car the better."
Caterham fitted several news updates to Charles Pic's CT03 in Bahrain and the team was pleased with their effectiveness. With the bulk of the updates arriving for next weekend's Spanish Grand Prix, Rossi believes the team can make progress.
"The good news from the F1 team is that we made some good progress in Bahrain with our performance."
"I think everyone was a little bit relieved to be honest because we've had some updates that have come and gone and they haven't really produced the results we were all expecting. The fact that we made a small step forwards in Bahrain is a good boost for everyone and we'll have more parts coming in Barcelona and at other races this year, although we have to take into perspective that everybody else will too."
Rossi missed the opening GP2 round in Malaysia but scored a podium in Bahrain and reckons there's no reason why he can't mount a title tilt.
"I don't see any reason why we can't have a run at the championship this year and that's what I've got to target."
"I've only scored points in one of the opening four races but I'm still seventh in the championship. There are still 18 races left so it's a long season and I wouldn't want to go into a championship thinking about anything other than a shot at the title."
