It's air cooling after all

the air cooling was different from other 2 yaris?
All 3 Yaris had much better stage times in SS4 than all morning. Q.E.D.
so you dont know if all yaris had engine overheat problems. Thats the answer you had to give at my question.
answer is not that ''they are faster vs previous stages''.
Off course I don't know if they had overheat problems, you don't know either. Heck often the drivers can't be sure either as the engine turns down power automatically (ref. Toyota engineer), supposedly without even telling on the dashboard (ref. Latvala SS2).

But based on times they clearly had much less issues in SS4 and the higher speed is for sure the reason. I recommend you actually read and think about whats written first. "Highest stage" doesn't mean much if the difference is a few 100m while the avg. speed difference is 30 km/h.
