Alfa Romeo development driver Juan Manuel Correa will get his first mileage in a Formula 1 car this Saturday in a Sauber C32.
Correa, who races in Formula 2 for the Alfa-aligned Sauber Junior Team, will sample the 2013-spec, V8-powered machine at French Grand Prix venue Paul Ricard.
The American will take over from fellow F2 racer Tatiana Calderon, who will make her third F1 test appearance for Sauber/Alfa Romeo in the C32 on Friday.
"Driving a Formula 1 car is something I have dreamt about since I was seven years old, so I am extremely excited to finally be in the cockpit," said Correa.
"I am looking forward to learning as much as possible from this experience. Thank you to Alfa Romeo Racing for this opportunity."
Calderon sampled the 2018-spec Sauber C37 in Mexico City last year before embarking on a two-day test in the outfit's '13 car at Ferrari test track Fiorano.
"I'm really thankful with Alfa Romeo Racing for giving me another opportunity to drive a Formula 1 car, following my previous two runs last year," said Calderon.
"I'm very happy to be able to work with the team on the track once again and continue to learn and develop further as a driver. I look forward to making the most from this new experience."
Correa is the higher-placed of Alfa's two junior drivers in F2 so far this season in 12th, with two second-place finishes to his name in his rookie campaign.
Arden driver Calderon, also new to F2 this year, has yet to score points.
