Wind Deflector

[mongo]

After getting the Urander enclosed bed cover installed as a base, I assembled this monstrosity we call (chesse) Wedgie.

Used OSB because Menards had 4x9 sheets and the final dimensions are 4.5'x9'x3' so only needed 3 sheets. Doing it in a more durable material will take six or so.

Seems to reduce Wh/mile by around 10% at 65MPH (1075 vs 1200), but that was only one test run. And I found out afterward that Teslamate had stopped logging (fixed that this morning).
Drafting (following distance of 7 in TACC) a semi at ~62MPH we were at 750Wh/mile .

I was thoroughly confused until I saw the last picture.

Me too!

Wind deflector for trailer for truck?
I've switched the photo order

This.. is one of those times I'm going to have to come down on the side of "aesthetics is more important than efficiency". But, thinking back, I do seem to do that frequently... (AT tires, running said tires without their covers...) Maybe I'm just anti-efficiency and never realized it.

That said, I'm adopting "Frontal Dominance" as my new stage name, so this thread was totally worth it.

It's a prototype to see it it's worth making a pretty version

Yeah, that's sort of what I'm thinking for a real version. Less flappy fabric though

Good Sir - Might I recommend a rattle can or two of black paint?

Yes, but that doesn't really seal (and would take ~5 cans just for the outer surface). Had also considered just going with rattle can bed liner. OSB needs a coat or two of oil based primer like Kilz shoved in the cracks with a stiff bristled brush followed by top coat of exterior paint.
Which I wasn't going to do until I had some actual test data. Paint costs more than the wood. It's a process, not a product.

So…is it?

It seems like it, but finding a semi to draft is a close contender.

How about that as an FSD setting?
Sloth, chill, standard, hurry, mad max and…draft.
all jokes aside though, it would be amazing to do behind a Tesla semi where the two vehicles could act together to get the benefit minus the increased risk.

Sloth and Chill are pretty conservative on passing so they'll draft a semi. I was surprised at the efficiency we had since following distance of 7 (TACC) is not at all close.

FSD Semi convoys would be cool, but a pain when merging

Not if they are in the fast lane
