The final six hours of testing began in similar fashion to the running on Tuesday and Wednesday, with Maserati driver Guenther top of the pile after the opening 20 minutes. He posted a 1m26.647 as his initial benchmark, and later took three tenths out of it.
Sebastien Buemi then brought out a red flag as he crashed at Turn 4 and required a clean-up operation, with a crane summoned to peel the Envision car out of the barriers after a suspected braking issue.
