Tyre assessment: two-quit method at the Japanese Grand Prix
The Japanese Grand Prix did not fall short to provide what was predicted following Friday’s extended operate simulations: significant thermal degradation and several quit method. F1Technical’s senior author Balázs Szabó analyses the tactics at the Suzuka race.
Subsequent the Singapore Grand Prix that observed Ferrari’s Carlos Sainz just take his and his team’s initial acquire in 2023, Max Verstappen bounced again in Suzuka, dominating the Japanese Grand Prix from begin to complete.

This afternoon, every little thing went as we experienced predicted and all a few readily available compounds were being employed, hence making a scenario in which we observed numerous distinct tactics concerning the groups and motorists. Immediately after learning the info from free of charge exercise, we reckoned that a two-quit method was the fastest and that was verified.
“People who tried out anything distinct, Russell for illustration, experienced to give very best in the closing levels to their two-halting rivals.
