2024 Model 3 (Highland)- Spoiler improves or reduces range?

[StealthgreyM3]

Does anyone know if adding a spoiler to my model 3 will reduce my range? I really like the look of a carbon fiber lip but range is important for me. My round trip commute everyday is 124 miles so every mile counts

Thanks in advance, hope someone’s already done this with their highland model 3!

Sure, adding a flat inch to the trunk lid will increase efficiency, and adding 2" would increase it more, 3" even more.
Where does it end?

This is one time that size doesn’t count.

Of course, sometimes a spoiler has its uses.

Now we're onto something.

The only thing missing is a shopping cart next to it acting as the shadow.

Let me know how that works out after a 165+ speed run,,,should be fun.

I don't know if it fits the highland, but supposedly the koenigsegg spoiler reduces drag

Up to $3500 for a spoiler? Holy moly. Someone needs to replicate this or 3D print it at least. $3500 is Ludacris, literally, for a stupid spoiler. Yikes.

Curious what their sales are. Zero maybe.

That spoiler is the same as UPP’s regular spoiler just overpriced lol

Oh yeah you're right, they quote the exact same numbers High Efficiency Trunk Spoiler for Tesla Model 3

It did look awfully familiar lol.

Overpriced and paying for the Koenigsegg branding.

Ok now I'm really curious about the sales numbers ha!

I have the UP front lip on my 2022 Model 3 Performance. I originally bought it because I didn’t want to get rock chips on that part of the bumper.

I didn’t do any controlled testing before I put the front lip on so I can’t really say if it helps at all. However, I can definitely say it doesn’t hurt efficiency.

I have been able to maintain 225 wh/mi or less lately. Most of the gains are due to the ultra efficient 235/45/18 Hankook iON EVO AS tires but my efficiency has always been better than when it was 100% stock.

The front lip is probably not worth the price for efficiency alone but if you think it looks good and you want to protect that part of the bumper then I think it is worth it.

I didn’t even paint mine. I just left it unfinished and buffed it down to make it look a little smoother.

Reminds me of this:

3D Hangar — Titan Dynamics

Home of the world's most capable 3D printed aircraft

These planes are 3D printed so it wouldn't be difficult to test out different shapes.

on the early Model S (2012/13), the same debate ended with multiple owners experiencing lower range with the spoiler. Good for looks and downward forces, but as noted earlier, if it increased range, Tesla would have put it there for base models

You do have a point. For all we know the wind tunnel tests could all be a simulation for marketing; however, there are members who say that it helps so I guess there's some substance to the claims..

As for Tesla, they can't even add in a simple blind spot indicator, so it'd be hard to give them the benefit of the doubt to do anything beyond bare minimum. As we know for them it's all about cost cutting. Perhaps the current spec of the spoilers on the Performance models are the bare minimum length, before crossing over into the no gain territory?

I would like to see a test of someone 3D printing a spoiler to extend further out from the UP one and to see how much that helps. In theory, the more tear drop shape the car is, the better the drag co-efficiency should be.

This is why the IONIQ 6 is designed the way that it is with the aggressive rear slope and duck bill spoilers making it one of the lowest drag co-efficiency EVs. 0.20 iirc.

Very curious now. Anyone have a 3D printer? I'll bring the drinks.

Could just wrap the spoiler with vinyl.
