Too much dampers and aero lately!
Saw this picture in one of Dimitris posts:


And it got me thinking. The Yaris has the radiators in-line with the intercooler first (also a massive intercooler) and the engine radiator second. It makes sense from a power perspective given that the colder and denser the air is, the more you can manage to squeeze into the engine. It does however channel warmer air through the radiator and could explain the cooling problems they had at warmer rallies. Do we know the other team's set up?
