- The Tesla Cybertruck is supposed to hit production in 2023, and in the meantime more informations keeps getting released. Recently, Elon Musk announced a quad-motor variant that will have some new features including crab walk capabilities. In today's video we walk through the new technological advancements including the 4680 cells and structural battery pack. Then we breakdown what we do know about the truck, and come up with an estimated weight, range, and battery capacity.

How much range do you think the Cybertruck will have? And what battery capacity will it take to reach that?
Note: If I didn't make it clear in the video, the calculations are based on the quad-motor variant which will be the heaviest
@@Christs_Apologet i've always thought that adding more motors increases power and performance by sacrificing range?
If I had to guess for a 500 mile Cybertruck, I would say battery capacity would be 180kwh. I think the Cd will be pretty good from Tesla and that the 500 miles will be on the EPA test. And as you pointed out, that will result in somewhat less range at highway speeds.
Elon has been pretty vocal lately that range over ~350 miles is unnecessary, but hopefully they still over 500 on a Cybertruck so that towing in the winter still holds up well.
I would look at Ford with the lightning and rivian as direct comparisons. The base lightning has a 98kwh useable pack targeting 230 miles hwy range. Which means around 2.3+miles per kwh.
I expect just like with almost all other current evs sold. That the tesla truck will have at least 20% better overall efficency.
So if they stuck with the base model ct having a 250mile range? Then the base rwd would likely have a similar sized pack as the current model a&x do which is somewhere around 99-103kwhs gross with 93-95kwhs useable capacity.
I actually think tesla might get 300 miles out of a base 100kwh pack ct though. I think tesla does a base model pack, possibly locking the battery for the 40k model's. And keeping it unlocked for the 50k model's. With the option for base model buyers to unlock it down the road. 🤔
I think they also simplify it and do the base pack with around 100kwhs. And do the large pack around 150-160kwhs useable giving around 380-400 miles of range. I think they don't offer the 500 miles of range at all now. Instead they rely on the 4680s with the new v4 sc offering a similar charging curve as the current cars can do. About 200 miles in 15-20mins which whoops all other trucks sold.
And call that good for the time being.

Model Y battery 450 kg 80 kWh
Cybertruck battery 900 kg 200 kWh
New Model Y battery 350 kg 80 kWh
100 kg less increase autonomy and acceleration .
This is a really good video - you did a great job making it easy to follow building up from basic physics to real world impact.
Great vid and analysis. You KISS'd it and thanks!
SS
nice physics analysis dude! what's your background?? you should legit be an analyst for EVs and tech companies! i like your logic
Excellent video as always!
The electric viking has consistently said that the Y with 4680 and structural battery pack saves 400lbs which is right with your 441lbs or 10% estimation. He also said a 4680 model S would save 250kg or 550lbs so it looks like the 10% estimation holds true with the S too. Does the 10% hold true with the cybertruck too? I'm thinking the 4680 cybertruck will save alot of weight and should not be compared to the hummer or Rivian.
If the pack is structural in the Cybertruck it will require more re-enforcement than it would in a sedan or CUV use case. Also the Hummer EV has armor plating on the bottom of the battery and rock sliders on the side. There's a reason it weighs so much. The other Hummer EV varients don't have the extreme off road package as standard so they will be several hundred pounds lighter.
The Silverado EV weight will be more comparable than the Hummer EV to the Cybertruck.
Another thing people are forgetting is GM said the Ultium modules are upgradable. Technically if you had the space in the pack you could have more modules added or as newer cell technology comes out have them replaced.
Speaking of sompthing else, i Saw that you added Aptera to your website, could it be possible to add other similar cars like the Lightyear one and the Sono Motor Sion, they are in a similar situation to Aptera they have finalized their design, and they are going to start to sell the motors this year or the next, in particular Lightyear One has similar principles to Aptera, there should be mass Drag coefficent and Horse power on wikipedia, you could put a beta on the name but the range calculator is great, (they have done some test on range aswell at 85Km/h and 130 Km/h), for the Sion i think is not so clear
How about XOS EV Trucks. ? Large EV trucks with the Semi returning in 2023. ?
I think you are very conservative. I imagine something closer to 6000 lbs weight, 150kWh, quad motor 1500hp, Cd of 0.25 and 500 miles range. Also I watched The Limiting Factor video which is projecting an even lower weight.
Great estimates used for your calculations. I'm speculating the exoskeleton gives them some significant weight savings from body structure alone, give that alone was the enabler for flight on planes. My ballpark was ~3 tonnes weight with ~200kwh pack for a robust 500mile range in real world conditions
Exoskeleton might not save much weight. Stainless steel is heavy and traditional car manufacturing uses mixed metals to get to whatever weight/strength combinations they need. So parts might be high strength steel, aluminum or alloy.
@theflew Time will tell.. Traditional truck design is quite redundant and wasteful with a frame, and then the body bolted on. A one piece structural body that deletes the frame should remove a fair bit of mass. Materials wise, this is SpaceX's own stainless steel alloy which is supposed to a lot stronger, so I'm guessing the gap between UHSS and SpaceX's concoction may not be as wide. Let's see ✌️
@@MADMAX7330 I think we'll see what the Cybertruck construction looks like when it's available. One reason Elon says the Cybertruck isn't available is because of its cost to build right now.
@theflew Give it a year. If you're insinuating that the Cybertruck is vaporware, and Elon will never get it to production, I'd say never bet against the man. 😅
@@MADMAX7330 I'm sure the Cybertruck is real. I just think all the beliefs about its cost, weight, and features are going to be off. There are Tesla fans that think the Cybertruck is going to start at $40k. That's less than a Model 3 and Y.
so, with an actual curb weight of like 6670 to 6890.. this means pack size is like 160-180?
Hey , motormatchup can you bring indian cars in your website?
Are there any specific car models you want to see?

Thank you for making this video. Although I believe the Hummer is a poor comparison. Just like its processors, efficiency was not a priority. It has 33% less MPGe than Rivian, which has 30% less MPGe than the model X . I imagine the curb weight reduction alone to be 20% to 30% of the Hummer, closer to your estimates without the battery. It would be interesting to see your figures compared to Model X efficiency.
Hummer is larger than the model X and can actually go off road. So that's a poor comparison. The Model X is closer to a minivan than an SUV.
@@theflewThe weight maybe, efficiency definitely no. Off roading capability was not what he was calculating.
@@theflew You should check out
The Limiting Factor cybertruck video they recently posted. It was the most thorough weight analytics I've seen yet. He also concluded the weight would be more closely compared to the X. More specifically, a quad cab King Ranch F150.
@@eternalbalance7703 Are you actually telling me to watch a video from someone that has nothing to do with the Cybertruck and say it's the most accurate so far?
@@theflew Recommended, your call.
I realise that you have to be conservative with your figures, but I think on a net of battery basis, cybertruck would waste quite a bit less than the hummer. Hummer is not sold in huge quantities and so GM can be lazy with their design in terms of culling weight and efficiency, but you can be sure that the cybertruck, designed to be sold in much higher volumes will be better.
GM also has armor plating and rock sliders on the Hummer EV. No mention of that on Tesla's site. Those add several hundred pounds alone.
It seems to me that your curb weight with battery is about 1000 pounds too high, and your coefficient of drag is about 0.1 too low.
Cd of Cybertruck is about 0.4, at 60 mph, less at higher speeds.
th-cam.com/video/6fuLD0R1iEU/w-d-xo.html
Cybertruck is the same weight as an F-150, per Elon at the unveiling.
th-cam.com/video/9P_1_oLGREM/w-d-xo.html
“The F-150's curb weight varies from 4,069 to 5,697 pounds, depending on the size of the engine, cab and bed”
shift.com/articles/how-much-does-a-ford-f-150-weigh
Edit: compelling arguments below. I am now convinced both the weight and Cd are good estimates. I was wrong.
That aerodynamics analysis video is interesting, thanks for sharing. But in it he mentions how harsh the software is. If you listen until the end, he says that the Cd is probably around 0.3 at higher speeds in the real world. Hence why I have a range of 0.25-0.35 because we really don’t know.
Also, a comment about the curb weight being the same as an f-150 doesn’t mean a whole lot. Tesla could easily be referring to the single motor variant with less than half the battery capacity. But yes overall my curb weight estimations are meant to be conservative.
@@MotorMatchup fair. …After further review, I now agree 0.3 is reasonable for the Cybertruck.
@@synchmanpe Rivian has a 0.3Cd so the likelihood of the Cybertruck being higher than that is very low.
Musk is still adding motors and features to the Cybertruck so I doubt he knows what the final weight is. The model X weighs over 5000 pounds with half the battery capacity and no real off road capability. So I would be surprised if it's under 8000 pounds.
@@theflew Compelling arguments. You have convinced me.
