Sauber has confirmed it will run Adderly Fong alongside Marcus Ericsson during next week's Pirelli test at Abu Dhabi next week.
In 2014 Fong tested for Sauber in Valencia and appeared in FP1 during the Abu Dhabi Grand Prix weekend. Fong, who is also a Lotus development driver, has competed in GP3 this season but has failed to score a point.
Sauber hopes he can complete 300km in the car in order to extend his superlicence. Once Fong has completed the laps required regular Sauber driver Ericsson will take over to continue testing Pirelli's 2016 compounds and new ultra-soft tyre.
"I am very pleased and thankful to have another opportunity to drive for the Sauber F1 Team," Fong said. "I will do my best to give valuable feedback. I am looking forward to it, as well as the aim of extending my superlicence after completing 300 kilometres. Last year it was great to have the chance to drive the Sauber C33-Ferrari during FP1 here at the Abu Dhabi Grand Prix. Now I am curious about testing the current car."
Team principal Monisha Kaltenborn said: "We are pleased to have Adderly in the car again and to give him the opportunity to drive a current Formula One car. He immediately put in a solid performance in his last opportunities for us. We are confident Adderly will again put in every effort in this tyre test."
