24-year-old Chinese driver Fong has competed in several single-seater championships in Asia and Europe, focusing this year on the Audi R8 LMS Cup, an Asia-based sprint race series.
Nissany, meanwhile, is a 19-year-old Israeli, who also holds a French passport, and is currently competing in his second season in the FIA Formula Three European Championship. He’s also the son of one-time Minardi tester Chanoch Nissany.
“I am very pleased I am going to test a Sauber C31 in Valencia,” said Fong. “It will be my first time driving a Formula One car with this high a power to weight ratio, and I am looking forward to it.”
Nissany echoed Fong’s enthusiasm: “I am delighted to have the chance to test the Sauber C31, and I will put lots of efforts into it to do a good job.”
Joining Fong and Nissany at the two-day test at the Ricardo Tormo circuit, which commences on October 22, will be Esteban Ocon. The 18-year-old Frenchman, who recently won the FIA Formula Three Championship in his rookie season, will be driving a two-year old Lotus.
