The number of red flags shown in the Japanese Grand Prix weekend grew to six on Friday night, with two more stoppages for grass fires at the Suzuka track.
After four stoppages (two for fires) in FP2, Friday night's FP3 session saw its first after less than ten minutes despite the FIA taking extra precautions overnight.
However, the vast majority of the session ran under green flag conditions once that first fire was extinguished, with around 45 minutes of clean running until a second fire terminally red flagged the session with six minutes to go, denying teams a chance for practice starts for the second day running.
The McLarens of Lando Norris and Oscar Piastri topped the timing boards as expected, but George Russell pushed them hard, putting his Mercedes barely a tenth of a second behind on his qualifying simulation run and setting up a fascinating qualifying session.
Yuki Tsunoda once again made his promotion to Red Bull look like a reasonable decision, setting a faster time than both Racing Bulls – although in the case of Isack Hadjar, only by a single thousandth of a second.
