It's air cooling after all



All 3 Yaris had much better stage times in SS4 than all morning. Q.E.D.


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.
drivers quotes from stage, tells me that you dont have a clue what happened.
you dont have to imagine theories with average speeds vs high altitude vs times from previous stages,when drivers said THEY SWITCHED OFF ANTILAG DUE TO HIGH ENGINE TEMP.

hope its clear now.
