I'm glad that this guy explained what drag coefficient is. Most people think that it's simply wind resistance or parasitic drag. The drag coefficient of a 747 is less than half that of the Cyber Truck
but it has far more drag due to its size and that it is designed to create lift.
Unfortunately, the Cyber Trucks claimed drag coefficient of 34 (38 tested) isn't as great as many make it out to be. It's better than a Hummer or an old F150 by a country mile. But it's pretty much in line with a new Chevy Silverado and not too far behind a Dodge Ram and Toyota Tundra. A good marketing department will make people believe anything without question.
12:59 Tesla has said that in the up position it improves aero slightly on that side of the truck. The reason it rests in the down position when intermittent is active, is because it's better to fling the water up and away from the vehicle (off the driver's side edge) than it is to push it down onto the frunk hood, which would just cause the air movement to push it back up on the windshield since there is no channel for it to go into like a normal car has.
Hey! Have you seen how Tesla shares have been performing lately?
Its for Snow
For the wiper, the overall drag on the vehicle may not be a large change when it is up or down. However, the air resistance on the wiper horizontal is more force on the wiper motor and joint components than when the wiper is vertical. Less stress on components over time is best, which is why design is to have vertical normally.
wind noise is also a factor, interrupting the airflow even by a low percent might cause vibrations and low frequency hums in the cabin, thats another reason why they probably perfer to have it vertical
According to an interview with Hans, I believe, the vertical wiper actual helps downstream drag as it wraps around the vehicle. It helps more understandably at highway speeds.
@@frozencold199 What do you think about the growth potential of Tesla shares?
@@dasoda_h_nahuel I think I'll report all your spam comments as they are irrelevant here.
Did you take out the mirror frontal area reduction in the equation?
Same for the lowering the car?
Frontal area get smaller and their correction factors for the tunnel should also change...
Guys, if I remember well, Franz said they were doing the coefficient also with the wheels moving - some edges around wheels are made with this in mind!
You are correct
Did they say in real life or on the computer?
@@i1Tesla i believe it was on one of the CT walkthroughs with Franz and Lars. It may have been a Highland M3 piece but pretty sure it was CT. They were talking about the wheel covers
This was so much fun to do... Great video and interesting outcomes!
Hey! Have you seen how Tesla shares have been performing lately?
Great effort on the whole thing! Most surprising was WITHOUT the side mirrors ... on other vehicles I've year 5%-7% 'MPG'. It is virtually no difference without the side mirrors on the CT.
MPG is a different unit though. Power to push through a fluid increases with velocity cubed. So no matter how miniscule the drag change, you can find a speed where you are looking at a large power difference, AKA MPG difference. Drag numbers here are not the same units as MPG and you need to multiply by the speed factor and cross section etc. to get the effect it has on total power or fuel consumption.
So on a dumb California "highway" at 55 to 65mph you will have a smaller MPG effect than say 85mph in the Texas panhandle.
Hey! Have you seen how Tesla shares have been performing lately?
@@dasoda_h_nahuel Look at the chart for the past several years. Look at growth of MegaPacks and other things in the pipeline. Tesla is more than cars.
@@Scott-sm9nm Do you have shares with the innovation shares? Especially with Cybertruck
@@dasoda_h_nahuel Your comments don't make any sense. You sound like a bot?
absolutely blown away with this testing....
Very punny 😂

Wow ok you when above and beyond for the Cybertruck team.
This is great content Brian! 👏🏾👏🏾👏🏾
7:10 yk you prolly have an exhaust fan within the room with you right now? maybe right on your lap for your laptop, next to you inside your desktop, or the one on your ceiling. Ceiling fans USUALLY have a switch to spin in the other direction during winter so it circulates rather than cools. Vaccums are NOT the only exhaust fan everyone sees day to day, and I highly doubt there are many people above the age of 12 that don't understand fans can go both ways
Would love to see comparison with Lightning and Rivian
Rivian did a lot of amazing tweaks to get better cD than Tesla has. See AirShaper's TH-cam video titled: Rivian R1T Aerodynamics - Is the claimed drag coefficient of 0.30 correct?
@@Scott-sm9nmwould like to see the tests in the same tunnel.
@@Dularr The key in this video is the comparisons (Cd) of with and withOUT mirrors, with and withOUT tonneau cover open, etc. ie. relative numbers.
The video indicated that on wind tunnels that are more compatible with taller vehicles that the manufactures numbers would be within 0.01% of each other. ie. believe Rivian's 0.30 and Tesla's 0.34. -- other approriate wind tunnesl would till be Rivian: 0.29-0.31 and Tesla: 0.33-0-35 -- the professional in the video clarified that.
@@Scott-sm9nm I'm responding to the desire to compare the various electric trucks.
@@DularrI understand. I clarified that Tesla and Rivian already provided their numbers. Then I clarfied that the professional at that wind tunnel in this video said that appropriate wind tunnels would be within +/1 of 0.01 to those so there is no point people spending the money and time to bring Rivian and Lightning to this inapproriate wind tunnel since you have the manufacturers numbers. HTH.
7:35 oh, hell yes! Thank you!!! I plan to take my mirror off when I get my CT next month, but good to know I'll have to use tape. I'll 3d print something until Tesla has a product.
are there any wires going to the mirror?
oh, 10:55 the mirrors don't really affect much
Since Tesla has those non radised edges that are creating huge vortices, it seem like a ' fix ' would be to install air fences like you see on the sides of semi truck windshields. ( They look like a spoiler tilted sideways )
Tesla could have kept the blocky look, but angled the A pillars to direct flow around there better.
I'm puzzled why they chose not to.
Very cool Brian! Love this, wish I could’ve been there too, thank you!
Hey! Have you seen how the Tesla innovation shares have been performing lately? Expecially on Cybertruck
Thank you. Love having the numbers. Surprised how little difference the mirrors made....
@@Christine_perkins33 preordered, but changed my mind and bought a Y last year. I wouldn’t be interested in buying a CT at current price, regardless.
Me too
I especially LOVED the last 15 seconds of the video. Subscribed!
Why? You good??
This is such a cool video thanks

Sick wrap!
Awesome video! First time I've seen someone do this for any car review.
Glad you liked it!
11:47 ride height and tonneau cover efficiency differences only really make a huge impact at speeds over 60 I would say. So in the city, feel free to open the tonneau and ride in a higher suspension setting (because it looks cooler at medium or high than down low).
cybertrunk doesn’t look cool either way so your safe
Very articulate comments by the young lady near the end.
Employee of the tunnel I gather so she would know her stuff.
THIS is the stuff I'm here for.
I love that wrap. Love it!
Thank you!
Interested in the results of a golf ball textured wrap on the surfaces that matter most.
Hey! Have you seen how the Tesla innovation shares have been performing lately? Expecially on Cybertruck
I'm sure driving on the highway with the tailgate down is going to be popular.😂
Dang what flow
You should look into laminar control on your smoke
awesome nerdy stuff here! It's going to take a minute to digest!
It took be a few days and I was in the tunnel
I love it !
For the mirror drag coefficient, did you change the size of the face?
Nice one!
13:37 I mean... it's a truck. But how does it compare to the Rivian (0.30?) or the F150's (0.44?) drag? (nevermind, I googled it)
Do my eyes,see 3m color shift deep space? Sure looks like it.
Great video. Can you share the info on the Wrap? brand/color? Thanks!!!
Oke this is cool and interesting thanx .....but now seeing this make me think this.... : if you want to make the drag les with that tailgate open (witte a lot of low stuf in it ) would it make sense to flip / hinge that strip of Metal Up ( wich the cover retreacts under ) like a small spoiler so the air would flow up and over the open bed and comes down behind the tailgate.....
In my mind not that hard to do and would it reep the benefits?? If so its a good small improvement
Great video very informative. I’ve been to A2 a couple times testing race cars I’ve been a part of. They’re great people and it’s a useful resource. But a simple tunnel like A2 has limitations, especially for low ground clearance racing cars that generate downforce from the under body. To accurately measure underbody downforce requires a rolling belt tunnel like they use a Wind Sheer, but that tunnel is massive $$$ and booked up for months or even years with pro racing teams. BTW, how much did it cost to run the Cybertruck in A2?
A question....
There's a ladder rack mount just above the tonneau release button.
(and towards the peak)
Would some some kind of spoiler mounted across those points be effective?
(Either the truck on it's own, or when towing?)
10:55 can you ride with the front lower and the back higher? or do both halves have to be the same height?
The thing is many different shapes would improve drag significantly....but does it look good is the question. Function over form or form over function...need to hit a good balance for both.
Don't expect the side mirrors to change the drag coefficient much since the big gain comes from the reduction in frontal area.
Unless you didn't account for that reduction, in which case the drag coefficient reduction is overstated.
I would like to see the same test done on a golf ball dimpled CT. Maybe shoot one up, speed dimples make it go faster.
I would love to see the Rivian tested in this same wind tunnel with similar configurations so we have compatible numbers. I think the Rivian would be the most interesting since it is the only EV truck with a lower coefficient.
Umm, the Silverado is .331, so also better than the Cybertruck.
@@AutoReport1 Umm, you have to make more than 12 trucks to be in the competition so Silverado is disqualified 🤭
@@TheLastMoccasin 461 last year, probably a lot more this quarter. How many Cybertrucks have been delivered so far?
@@AutoReport1 More than that... Pretty sure Silverado will be fighting for 4th place after Rivian, Ford, and Tesla for 2024 total EV trucks sales. Nice looking product but it's a shame GM is struggling so much with EVs right now. All the software issues are really making them look bad.
@@TheLastMoccasin Tesla is grouping Cybertrucks with X and S as "other" so it's really anyone's guess. I'm guessing since we have some weeks to go, Silverado will be at least 1000 in the first quarter.
To improve a car it is most likely more important to measure the relative drag changes when comparing modifications, then to have a very precise absolut value.
Nice Aerostar
I think the vertical wiper had an effect similar to winglets on an aircraft avoiding "spill" over the edge and reducing the vortex?
I am sure some entrepreneur is going to make some add-on kits for the CT to make it more aerodynamic, especially the front and rear and something to address the turbulence around the sharp edges facing upward
cool to see but to be fair i don't think it is very telling along the sides of the truck due to the small size of the wind tunnel the air flow along the outside is much slower then the center especially with everyone standing on that same side. You would need a wind tunnel approx, twice the diameter for proper laminar flow along the sides of the truck.
10:50 is it possible to test tonneau closed trunk open?
how about wind test a gas car and see the difference between manufacture number and this wind tunnel to see if the difference between both is the same.
That vertical front plate could be given a sloped treatment and it will make a big difference
Good test
Thank you!
There's a place where it's legal to drive on the freeway with the tailgate down?
Huh I thought Tesla had a plastic cap in the dash that is made for the mirror hole?
Wiper down could induce more wind noise
Nice video and presentation.
Test with smoke stream give us qualitative experience and not qualitative data.
We do smoke trail test in wind tunnel for the lack of understanding in aerodynamics and by association with these test as such gave us a cool appearance in front of those who also don’t understand the subject.
To turn that around and show we do understand the science try to reconfigure the test w/wo blowing smoke. Example? Reconfigure the test from vehicle wheels resting on floor to resting on frictionless linear bearing glide rails. Attach a strain gauge (newton or kg scale) between vehicle and a test ground. The reading is the net drag caused by the wind and vehicle shape. Experiment? Record the force in a stick configuration and change something deviate from stock condition to see difference in drag for a qualitative analysis.
Hope this helps
Next, Poor man’s wind tunnel alternative for quantitive data?
The same test may be set up without a wind tunnel. You’ll need to decide safely factors before conducting it.
Attach the strain gauge between the vehicle under test and a tow truck or a second cyber truck, both on a quiet and smooth lane without traffic.
The reading is the total drag including aerodynamic and rolling drag. Record a base line force then proceed with configuration deviation to learn the cause and effect. Caveat? Turbulence of tow vehicle may cause some bias in data. Alternative? Use push instead of tow. Proceed with caution.
Thanks for reading.
Also, how does the tunnel account for the people standing in the tunnel?
We where in a different room during the tests. Only in the tunnel for the smoke
@@i1Tesla ahhh got it

Tesoro’s sells a Cybertruck wrap kit. Will you comment on it?

Good video but I can't read the graphs on my phone. Gotta be zoomed in on the video
You wouldn't think it was aerodynamic until you realise that both a cow and a Volvo 240 are more aerodynamic than a Lamborghini. Very interesting video guys.
Lambo isn't designed aero efficiency but rather high speed stability so they literally add aero for down force.
@@officialyasir No shit Sherlock? You will find, however that original, pure shape has very little areo and a cow still beats it.
Great explanation of what coefficient is for us dumb-dumbs out here :)
the wind tunnel itself is a cybertunnel shape
.34 to .35 is a good aircraft number for drag.
That would be pretty typical for something like a Cessna 182. Large airliners get down to about half that.
what chemical do they use for smoke?
aircraft smoke fluid.
@@marvindebot3264 oh, cool, thanks!
Why wiper down? (pardon if I missed reason, skipped some)
In intermittent mode, it rests wiper down because moving the water up and off to the side it can't blow back onto the screen.
@@marvindebot3264 It has a dramatic effect on aerodynamics which is why it's not normally parked there.
Go watch the 911 turbo s vs Cybertruck dragrace....The guy driving the truck said at 80mph he could feel the truck being held back from heavy wind friction........
Maybe youll want to do some real world testing and let some tail vacuum & drag along with some side drafting do some of the talking..........
You're comparing a sport car to a truck...
Gee whiz then why did Tesla post a video of a Cybertrashan beating a Porsche while towing a porsche trying to look like the cybertrashcan can actually beat porsches so go take your comment and shove it where the sun doesnt shine buddy,,,,, how does the facepalm taste? th-cam.com/video/OyrTLYyIvNI/w-d-xo.htmlsi=bsi96kP8VEKJ2x2f

1:27 wait, did he just call the Cybertruck "not a real vehicle?"
So what's the final outcome?
Drive in low mode
Should have tried it in reverse just for giggles!
Every fan I see sucks "air" in and blows it out. That's not a revelation my guy. Lol
Can you not ask Lauren to make some calls ?. She is an attorney right ?.
So I took the mirrors out for nothing? D: lol Expensive mod to cover the holes. Lol
Why "Wrap" it? What's your point?
I'm guessing fingerprint reduction.

Tesla should have Hidden the wiper blade
This test is a bust .. why the wiper is not vertical ?
No mirrors I see…
Its a truck in the end. Not a Lamborghini or Ferrari
headphone warning: 3:16
Wiper down is putting a lot of force on the wiper itself. Not good for it.
It ain't gonna hurt it. The air can't compare to rain, sleet, ice or snow.
@jamesengland7461 I don't mean like break it, but in the long run, it'll wear it out faster and the blade will deteriorate much quicker.
Correction, the truck is covered in curves.
Why do ppl put background music louder than their talking voice?
Awesome video.. and those fans suck
85 MPH. Big suck
lol Tesla would use a modified car with an extra slick wrap for their test that doesn’t come on any factory vehicles. Why do they keep doing shady stuff like this? The Porsche 911 video was already disproven to be fake as well. They say the wrap doesn’t affect anything.. well then okay, do the test without it then and let’s see.. oh wait they won’t
I would like to see if this comment shows up
You did it
Car/truck radiator fans suck, almost all of them. All kitchen extractors suck. The average paint booth fan sucks. It's an endless list.
We all know that EVs get horrible mileage as speeds increase. Why is this not as big a factor on ICE vehicles? Is it due to the transmission and axle gearing in the ICE vehicle?
It's exactly the same for ICE vehicles. Gas consumption goes way up the faster you go. But most gas cars don't have precise enough data or display of data so drivers not aware of it.
Yes, but the percentage difference is way larger in an EV. Maybe due to cooling of the battery and just battery heat zapping energy.@@Martinit0
We are testing this truck. Are you towing a boat to a lake and taking it in and out of the water - no. Are you plowing a driveway - no. Are towing a camper up and down a mountain pass - no. How about showing how to attach a winch - no. For sure you are doing some muddin - no. How about loading gravel into the bed and hauling - no. How about going to hunting spot in the woods - no. When do the truck test come? Does anyone use it as truck or are they just used to create TH-cam content?
I know a good website for you. It's name is TH-cam i think. On it you can probably find all tests you need. But in this video, i think, but i can be wrong, it's just a wind test for efficiency, like on highway.
It still has better aerodynamics than your average truck in any scenario you clown
That is my point. There are no videos of those things.
@@theplouf5533
Will the majority of Cybertruck owners do any of those things? No.
Tesla lying about numbers. Who would have expected?
Did you not see the part of the video where they explained how their small tunnel is distorting the results and that a bigger tunnel would give more accurate results for a vehicle the size of the Cybertruck? You most likely saw it, but chose to ignore it in an attempt to try and crap on Tesla. That is getting exceedingly hard to do with any credibility.
@@donm2255 He said different wind tunnels tend to vary by about 1 point, not as large a difference as they noted. Tesla has a long history of lying. Get Elon's cock out of your mouth long enough to think critically. He's not giving you a pony.
Clearly you didn't watch the video.
This is a cheap wind tunnel
They tested a Model S and got very close to Tesla's numbers.
Almost identical.
As was stated in the video, this truck is rather large for the tunnel, and that may have skewed the numbers.
Of note was also the different wheel and tire combo on this Cybertruck.
Personally, I think 'Moon' wheel disks like you see on racers at the Bonneville Salt Flats would look right at home on the CT.
Especially since it was designed to look "retro future " and all those vehicles have wheel disks.
That's one ugly truck.
No moving floor and too much blockage.
There's no saving grace for this inefficient battery-sucking garbage can of death.
