Surprising Aerodynamics of Champion Subaru Impreza

See how a splitter plate helps this Subaru Impreza WRX's downforce production and drag here: / premier_aerodynamics
The Subaru Impreza 1996 was one of the greatest rally cars ever. But was it aerodynamic? The results are surprising!

And that's the reason why almost every sedan nowadays is a fastback or has a sloping rear window.

Hello@@PremierAerodynamics , I wonder if analyzing the aerodynamics of an EUC rider would be interesting for you? I'm very interested in this (because I ride a monowheel;)) I found some of the answers to my questions in your video about the aerodynamics of a character/person sitting on a chair. You have very interesting content. Regards ;)

[@SlimothyJimothy621]

Looks lamer tho, you gotta figure if you want looks or aero

[@elektro3000]

Okay, we've spent a lot of episodes looking at cars with varying levels of effort to optimize the aerodynamics. Now let's see a vehicle where they did not care at all: 1980-1986 Ford F-350 four door dual rear wheel 4WD (important because of the different front axle from the 2WD) with the giant towing mirrors.

[@PremierAerodynamics]

Thanks for the idea!

[@rolandotillit2867]

That's cool, your simulation picked up the buffeting from the rear glass.

[@PremierAerodynamics]

Thanks man!

[@test987665]

Hmm, I am not sure how accurate this simulation is. There is no way that the car was lift neutral. I think the problem is that the models don't model the underside of the car very well and instead assume it's flat... even though on these older cars it was anything but. The flow under the car was probably a lot more messy in reality, increasing both lift and drag.

[@iamcarl4591]

This simulation clearly doesn't take holes into account. The hood scope, underbody components, radiation, etc, was not taken into account, of which, is the most common factor of lift. In this case, the WRX, has a lot of huge functional holes, which could increase drag and lift. The worst aerodynamic part of WRX is always the iconic hood scope, there's a reason why rarely any modern car still has it.

[@Claudio_And]

Car designer here (again). Some videos ago, we discussed this in the comments. You guys are correct, these video game models are used for visual purposes only. No underbody or air intakes are modeled correctly. In car aerodynamics, the flow inside the vehicle is sometimes more important than drag alone. This hood scoop is a great example. It is more important to supply the intercooler with cold air, even if this means a little more drag. The engineers behind this project knew exactly what they were doing.

[@Claudio_And]

by the way. It is interesting to note that in every video, the airflow under the car is always "pretty good." Regardless of the brand, model or year.

[@PremierAerodynamics]

Thanks for the input!

[@DctrBread]

@@Claudio_And i was wondering about this. Not much point in trying to model the aero on a car unless its been modelled very accurately and in high detail to the real car. the placement of small grooves or bumps can really impact the downstream effect, was also thinking we need to see whats going on when the tires are actually rolling.

08 STI wrc car would be a cool comparison. There is a reason most manufacturers changed to a hatchback for rallying.

[@PremierAerodynamics]

Thanks for the idea! It would be interesting. The hatchback might also be something to do with the weight distribution.

[@poetsrear]

​@@PremierAerodynamicsI also expect hatchback to have better support-to-weight ratio. The shorter, more round unibody skeleton is probably more resistant to rolling damage and frame bending. Sedan is longer and flatter, thus "bends like a bar"; hatchback is like an internally arched pod and "bounces off rather than crash & bend". This is layman speculation though.

It's cool to see a visual representation of the aerodynamics, and then piece together why modern cars look the way they do. I've noticed a lot of car designs make an effort to "pinch" the rear airflow around the rear window. Love this channel!

[@PremierAerodynamics]

Yep, and also to reduce something called the "base area" which also reduces the total drag.

[@PremierAerodynamics]

Thanks for the idea!

[@jamsbong]

analyzing the wake is just one aspect of external aerodynamic behavior. You need to look at the pressure plots on the surface of the vehicle. Much of the reason why the spoiler version of the car has less drag is because the flow over the rear windshield is slower and thus does not result in so much low pressure on the surface that acts like it is pulling the car back. I always look at the drag and lift coefficient along x-axis first and followed by the surface pressure plot. The wake analysis is more for visuals and not always useful for understanding the flow. Generally, wake is unavoidable, but you can try to place them in a good location.

[@windowsxseven]

KZbin "aerodynamicists" are generally clueless, get used to it

[@PremierAerodynamics]

[@ertgery9084]

Do you take into account that the front part of the car and the intake on the hood take in air and throw it under the bottom or onto the windshield?

[@Voting-does-nothing]

Exactly mate 👍 A ton of air goes in the front bumper the then out the upward facing vents on the bonnet, Plus the scoop catching and pushing air directly under the car must affect things. Im sure the 1999 version also had the steeper bonnet angle too ?

The Nissan skyline R33 GTS-T came with 3 different optional wings. (Round where it continued the curvature of the side over the whole boot, flat, where it raised just a little then was a flat plane and GTR where it was lifted substantially, extended beyond the side mounts and was a flat plane) It would be cool to see the difference between each of these.

[@Danger_mouse]

Thanks for doing this one. I'm an ex mechanic owner of a 98 GC8 WRX, so was interested to see how it faired. 3:41 The A pillars have little dams built into edges of the front screen rubber filler strip. While this does force air up and over the roof, it also forces rain and wiper water up there too which is important if the windows are down a little during rain 🙂👍 * The STI did have a different spoiler fitted at the factory, and I recall it came with the tall extension blocks to stand it right up in the air stream at about 1/2 window height. Also, I recall the last WRC GC8s had vortex generators fitted when they moved to the 2 door, which no doubt also helped with the rear glass angle. 👍

[@PremierAerodynamics]

Wow, I didn't notice the little dams. That is a nice feature for the rain.

[@maxbroke7054]

You mentioned the roof being a low pressure area and would be better if the car (and roof) was a bit longer. The Impreza is a shortened legacy (or whatever it was), where subaru just took their at the time highest performing road car and shortened it for rally use, and I guess they didn't consider the aero affects (like the roof lift) from doing so.

Also intercooler drag from the scoop on the bonnet would increase lift/ pressure under the bonnet.This air has to go somewhere,which would be under the car creating more turbulence again not good for drag.

Curious where the best place to put a wing on the hatch back version would be, as well as finding out the drag coefficient. Good to know I should change out the mirrors and grab some more arowdynamic wheels.

[@PremierAerodynamics]

If you mean the wrx hatch, I would probably leave it how it is because if you put a wing on, it will likely reduce its handling because the front to rear lift ratio will be changed. If you do put a wing on, then at the back on the roof, but then you also need to increase the splitter at the front to increase lift there too to keep the handling decent.

[@GoddessOfMisfortune]

if you look at aftermarket and subaru racing mirrors from the time, you'd notice how much smaller and aerodynamic they were designed, such as the wrc mirrors, or the famous Ganador mirrors. Would be curious to see how those affect this.

It would definitely be better for downforce than this wing, and for this model, you probably wouldn't get much of a drag penalty. But, for ones with the flow attached down the rear window, that roof spoiler would increase the drag dramatically because now you have a much bigger wake.
