I’ve long wondered about those vents myself in heavy rain. While driving, not so much, but it’s a factor. The bigger issue is when the vehicle is parked. So I’ve questioned the functionality. Non CE hood, you don’t have to worry about rain water cycling through the engine bay. So even now I don’t even know if the venting of the engine through the hood vents is worth this trade off. Especially, for people who are going to drive in all sorts of inclement weather. I’m not buying an AWD hatchback to drive it only on fair weather days. If that was the case I’d go RWD.
