Raffaele Marciello is confident he will "do a good job" when he takes part in Friday practice for Sauber in Malaysia this weekend.
The Italian, who is part of the Ferrari Driver Academy and tested for the Italian squad in Abu Dhabi last year, has been named Sauber test and reserve driver for the 2015 campaign.
He will get his first taste of action in an official grand prix weekend though with the 20-year-old handed the driving duties for FP1 at Sepang, with Felipe Nasr making way.
"It will be exciting to drive the Sauber C34-Ferrari for the first time [in FP1]," he said. "That will also be the same for the Italians, as we have not had an Italian driver in Formula One for quite a few years.
"I will definitely enjoy the experience, and I am really looking forward to it. I am confident I can do a good job as well as supporting the team in order to find a set-up for the car which suits the track.
"I have never been to Malaysia before, but I know the track quite well from the Ferrari simulator in Maranello, and I am sure I can get to learn it fast once I drive there.
"As the circuit has some fast corners, I think the car’s downforce will be crucial. Another important aspect will be the weather, as the humidity, along with the temperatures, is quite high. From a driver’s perspective it will be a challenge, but this is the same for everyone. Together with my trainer, I am getting well prepared for this weekend."
