The Japanese manufacturer caused a surprise by registering 52-year-old Sasaki as a third driver for the final test of the pre-season alongside its usual drivers Takuto Iguchi and Hideki Yamauchi in the works R&D Sport-run BRZ.
Sasaki previously drove for Subaru between 2010 and '14, his stint at the team coinciding with its switch from the Legacy to the first-generation BRZ that was only replaced by the current car in 2021.
