What is the purpose of fender vents?

The main purpose of fender vents is to relieve built-up air pressure from inside the wheel arches which causes aerodynamic lift. Typically, there are air intakes in the front of the bumper directing air over the brakes to cool them. This air gets trapped in the wheel arches and creates high pressure. High pressure results in lift over the front wheels reducing traction. Relieving this built up high-pressure system in the wheel arches reduces front axle lift thus increasing safety and grip.
In addition to high pressure, trapped air in the wheel arches also creates aerodynamic drag. Drag is the force of air pushing in the opposite direction of the vehicle, reducing efficiency. Some research suggests wheel arches account for up to 30% of aerodynamic drag of a vehicle. With fuel efficiency ratings becoming increasingly more strict on modern vehicles, you can understand why so much attention is being directed towards the reduction of this inefficiency. Efficiently routing air into and out of the wheel arches increases fuel economy through the reduction of drag.
Another benefit of fender vents is to efficiently vent hot air generated by heavy breaking out in the air stream. Quickly relieving hot air generated from the brakes makes room for more cool air to pass over the brakes, thus increasing efficiency. Finally, it is worth mentioning that trapped air in the wheel arches also contributes to cabin noise. Reduction of cabin noise is more pleasant to drivers on long trips reduces driver fatigue.

Yeah, it's probably no coincidence that there are side vents now that there are real front vents that feed air into the wheelwell.

So probably the *real* benefit for those of us who track these cars is more brake cooling without any additional lift or drag.

Thanks @ZDan, @StE92ve for pulling me off the ledge. Given they are functional (at least according to Subaru) that eases them a bit. Still, they look like an afterthought and the part of the new design I like the least, only slightly below the Civic backend.

I think the new BRZ rear end looks great.

Corolla hatch looks great as well, for a fwd 5-door hatch econocar.

I think the BRZ's rear end looks "better", but I would be 100% down for a 3-door BRZ/GR86 with Corollaesque hatch

Somebody p-shop that for me...

Well this is a Gen1 but you mean this?

Something like that, yeah!

Aesthetic nods to the past (e.g. 2000GT) are fading with the 2nd gen.
The 2nd gen is basically a modern nod to the 1st edition, i.e. the BRZ now has a past of its own to draw from.
This reminds me of what happened with generations of Miata, i.e. the NA being a nod to e.g. the 60s Elise and other British roadsters of that era, and subsequent NB-ND basically riffs on the NA itself.
I can definitely see how some new owners will be very pleased with the 2nd gen, but for now I’m really glad I still have my ‘17 1st gen refresh.

Would be awesome if they offered satin black as one of the options.

The part of the car you circled is my entire problem with the design. It looks way too ricey for me. I am not sure how functional they actually are. I suspect they are adding all these aggressive vents all over the car because that is what the average buyer wants nowadays. Just look at all the ridiculous fake vents all over the current Civic Type-R and the Supra.

New BRZ vents are real. Please refer to posts 1333-1335.

Damn, it does just keep looking worse to me. Bulbous, bloated and uncohesive lines just scibbled all over the place.

TheDonEffect · 01-14-2021, 01:53 AM

Still looking good to me. Man, this radio silence from the OEMs is killing me.
