The new 2020 Supra is set to come out soonish and the car is covered in ‘fake’ vents. These vents aren’t functional (from the factory) but the plastic filler can be popped out and replaced with real (functional) vents for people that tune the car and make it faster.
One of the reasons Toyota said they didn’t make all those vents functional to begin with, is because it would over cool the engine. Why would this be a bad thing?
Edit: a word
In: Engineering
The engine operates most efficiently when it is already moderately hot. Increasing it’s ability to vent heat makes that sweet spot farther away (which is bad if you are just driving casually but good if you are constantly pushing the limit).
