Independent Aerodynamic Study of Tesla Model 3 by Unplugged Performance
The OEM spoiler reduces drag in this analysis.
So did your wh/mile increase? like did it go from 245 to to 270 or did it go from 295 to 270? And wow your car looks amazing!!!!!!!! I love those wheels.I have the front lip and the lip gained me 10 wh/mi and the spoiler another 15 wh/mi. I’m happy with the looks and efficiency at 270ish.View attachment 604183
It’s went down. I’m on 20s open face wheels flush fitment and still down in the 260s-270s. Haters are gonna hate so don’t listen to them. Yeah you can get “solid” wheels and get way better efficiency but fcuk that...my car isn’t gonna be boring for efficiency. This solves that problem and looks awesome.So did your wh/mile increase? like did it go from 245 to to 270 or did it go from 295 to 270? And wow your car looks amazing!!!!!!!! I love those wheels.
eaiser said then done.All that stuff is hype and looks if it really works Tesla would have has a option or even on their cars.
eaiser said then done.
Cost of labor+parts+health insurance+training+overtime ... does it justify the option? will people buy it?
How much time is added in production cost?
all genuine questions with real calculations
sometimes it's better for aftermarket company to solves issues OEM don't want to touch
I don't have the exact answer since I don't work for TeslaLet's flip your question - you assume unplugged has the resources to support everything you quoted above? (Or, a generic aliexpress shop?!?)
They will get the production scale anything close to tesla? They can sale in the volume anywhere close to tesla, to pay back that development cost?
What's easily done is drafting a base spoiler design and running stochastic simulation to tweak the shape and optimize for aero. What's not (because it's costlier) is to prototype the shapes and run actual physical testing on it. Where are the wind tunnel results?
My grandma can produce a fancy looking 3d render with blue and green streamlines by paying 4$ to a kid on Fiverr to draft it up on a pirated copy of solidworks.

Damn dude...who pissed in your coffee this morning? No one has a gun to your head to make you buy it. There’s a button at the top called “unwatch thread”. Do you know how big Unplugged is? It’s pretty obvious they have the resources to do CFD testing. No one else in the aftermarket space is claiming any benefit except them. You think they would put their reputation on the line for a false claim?
Can’t really call bullshit when people are actually backing up their data with their data soooooo....You're missing the point - CFD modeling takes next to no resources at all. So their "white paper" serves no substantiation except to impress lay people.
Theyre not exactly Dinan. A new upstart Tesla centric vendor doesn't exactly have any reputation to protect. And I'm not saying they make outright lies -- I'm saying it's low grade marketing wankery just like the countless "reputable" aftermarketer vendor who claim their intakes and exhausts adds 15 horsepower each.
It's not malicious enough to be punitive -- nobody is going to take AEM and Steeda and Borla to court over it -- but we're all within our rights to flag bullshit when we see it.

Let me know when you want more screenshots. If I can beat this number daily...it’s not bullshit.
FWIW, while I'm in the "I'd love for this to work" camp and am generally really sour on the "It'll never work because..." mentality that's all to pervasive when it comes to something new/different, I'd maybe suggest a little more data driven to your data set. Its easy to pick holes in an analysis when the error bars are unknown to the audience (other vehicle modifications, seasonality, software versions, etc); if you're really fixin' to justify efficiency gains more diligent record keeping would go a long way.
While @holmgang's delivery might be a little salty, the points are valid. Like, even if Unplugged did some best-effort real world before/after test, it would go a long way to validating their claims in the white-paper-that's-not-really-a-white-paper. Even if they could reproduce, say, 4% efficiency vs their claimed 6%, most reasonable minds would allow Unplugged to hand wave the 2% difference with a rational explanation of 'real world' variables. Or, you know, just advertise 4% ("But calculations show it can be more like 6%").
FWIW, I have Unplugged mild springs on my M3 and love them (installed at Unplugged, in fact). 100% the way the car should come from Tesla.
Yeah, I agree with this. I think there very well could be manufacturers that will come with parts that could improve efficiency. But as @bxr140 said about @holmgang response, it may sound harsh but technically many valid points. Even claiming there are people out there who have 'proven' to have better efficiency cannot be called proof. Did they test in exact same conditions? same temps, same humidity, same road, same traffic, same wind, tire pressure, tire temp, and tire wear? That's impossible to do. The only way to accurately do this is in a controlled environment and with accurate measurements in place.
So I'm not saying their parts don't improve efficiency, but there's not really any true data to back it up. Someone saying now they're able to beat their efficiency consistently from previous just leaves way too many other possible variables to call that 'proof'.
Personally, I think it's entirely too easy to be a skeptic on the internet, as it's a relatively safe position to argue from. Nothing on the line, the burden of proof is on everyone else, and there is always an "out", by calling some variable into question. So I agree with you, the general air around this topic isn't the best.FWIW, while I'm in the "I'd love for this to work" camp and am generally really sour on the "It'll never work because..." mentality that's all to pervasive when it comes to something new/different, I'd maybe suggest a little more data driven to your data set.

I decided to test for myself, since it's an area I'm interested in. In my 3, I decided to drive a regular ~30 mile route that I often take my cars on, which consists of long stretches of highway, using an average cruise speed of 70mph (in the 65mph zones), and 60mph (for the 55mph zones). I warmed the battery before starting the factory spoiler test, to better balance temps against the following UP efficiency spoiler test, but otherwise, my tires were inflated to 45psi, it was a mild 70 degree day, dry and clear. Distance travelled was exactly 29.3 miles, using the same 7kwh. With the factory spoiler, I averaged 236 Wh/mi, while the UP averaged 233 Wh/mi, start to finish. There was naturally more variation once I pulled off the highway, but as I monitored the tests for the highway portion, I was consistently 2-3 Wh/mi lower than the factory Performance spoiler on each stretch, which was indicative of the entire run.
...
One last takeaway as to why Tesla may not have done this from the factory (and this is just my personal opinion), is that building cars for aerodynamic considerations (primarily) is very polarizing. The Honda Insight wore rear wheel covers and people either loved or hated it. The 3 has a very "distinctive" front end. The aero wheels on most EVs aren't the most attractive. If you've seen some of the mods people do in extreme hypermiling, it gets really out there. Likewise, a spoiler which trails the car (even this much), will turn a lot of people off. The reason the Model S was so popular? It performed well AND looked distinctively good. Once you start to deviate from the norm, you really do divide opinion and I think aerodynamics definitely play in the realm of function over form, and sometimes practicality.

Let me know when you want more screenshots. If I can beat this number daily...it’s not bullshit. Also my mods occurred during half of this lifespan of the car and the mods are especially worse ie wheels/tires.
like I said...don’t buy if you don’t believe. Let other people make their choice but you cant call bullshit if you don’t own
