Cybertruck = UGLY
I don’t think the 4680 have tabs. And an extra tab at some specific place in the jelly roll won’t make that big of a deal when not at high rates. I can say from data I’ve taken, the 4680 is not a rate capable cell…I am a huge fan of the 4680's, but it does seem that the limitations Tesla imposed on itself during the design really did reduce the internal "roll" height a bit. Along with the first few wraps not having tabs at all. In the end these cells are about 295Wh/Kg and about 26Ah each. There is nothing shabby or substandard about the cells. Only that Tesla did not include enough of them.
Each cell has about 2375 square centimeters of electrode surface area.
BMW is going with a very similar configuration, but 4695 cells (95mm tall instead of 80). The geometry of this change gives a healthy 26% increase in energy. Simply because the roll inside has 26%-27% more electrode surface area than the 4680.
Remember, the 46 is the diameter in mm, and the 80 is the height in mm.
BTW, the battery capacity is 122.4 kWh and achieved 254 to absolute dead.
The F150 Lightning is 131 kWh and achieved 260-270 miles to absolute dead, at 70 in ideal conditions. Other tests are lower.

did out of spec, publish a towing range coupled with supercharge times?
I like Kyle, with the exception he doesn't use a character generator and show the results of his tests on screen.They said there’s a full charging curve video coming soon. Kyle Connor’s comments on a few podcasts seem to match the photos posted online in December. It charges well (250kw) through about 25% then drops-off massively. Charging is fair-poor overall, similar to the slow charging of 4680 equipped Model Ys.
Not sure about towing, but they did bring a trailer down to Austin. They might have mentioned they ran out of time to do a full towing test.
I haven't seen it yet, but I'm guessing no. I don't remember seeing Out of Spec doing any towing reviews. TFL Truck will definitely put it through its paces with their towing tests and their regular car channel tests a lot of EVs.did out of spec, publish a towing range coupled with supercharge times?
I referenced it in another thread, but the Out of Spec range test is now published with numbers.
Dual motor with stock All-Terrain tires. Steady 70-MPH. Zero wind, zero traffic, nearly zero elevation (Austin TX), 45F
100% - 0%: 242 miles
100% - unable to hold 70 MPH: 249 miles
100% - totally dead: 254 miles
More realistically, go from 90%-5%, add in some wind, traffic, a few hard accelerations to merge and this is barely a 200 mile vehicle. And the Tri-Motor “Cyberbeast” version gets even less range.
Let’s just say there’s a reason they came up with this last-minute idea of a range-extender they’ll install in the bed…
In summary, it’s worse than the Lightning (ER Pack) or Rivian and FAR worse than Hummer EV or Silverado EV
The biggest problem is that Tesla decided to forge full speed ahead with dry coating on the cybertruck. Unfortunately engineers have told musk that technology doesn't scale up well and from their numbers Tesla will be lucky to buildI am a huge fan of the 4680's, but it does seem that the limitations Tesla imposed on itself during the design really did reduce the internal "roll" height a bit.

Out of Spec is peak dork? Possibly, but he makes a lot of money doing this stuff. I will say I do like his videos. It satisfies my inner nerd when it comes to long range EVs.Peak dork. These guys don't get out much.
Also, "nearly zero elevation" in the Austin area really depends on which way you go. I have ridden my bicycle from SW Austin to Fredericksburg and back on country roads and the Garmin indicated 12,500 feet of elevation gain for the (long) day. About 186 miles, IIRC. and 16ish hours including stops.
Regarding the test, can't say I'm really surprised. None of the EVs in the marketplace meet their EPA ratings at the kinds of speeds we drive on the highway in Texas. I'm guessing you'd have to drive 60 or less to meet the EPA range, which would definitely not be safe on the 130 tollway.
If I bought one of those things, the first thing I'd do is get the lowest rolling resistance highway tires available. I'd bet that would be worth an extra 20 miles at least. Nobody is going to take these things offroad, at least, in the initial tranche of buyers at big, big money. And if you can afford one of these things it doesn't seem like such a reach to have two sets of tires for it anyway.
Battery density is not yet there for serious towing work, even the most strident EV fan would admit that. You'd have to buy a Tesla Semi to tow a 5th wheel a useful distance, and then, how do you charge it? No public use Mega chargers out there.it will disappoint towing every single time.
The types of folks buying CTs don’t care about the environment lol. They’re all hypebeast influencers that worship Elon and his weird anarcho-capitalist/chud libertarian mindset.Just the feeling of saving the planet makes any short falls of an Ev worth it.

It's the same all the other EV trucks in the end, if they can sell any of them at a price approaching the original $40K of the Cybertruck, they'll sell quite a few, but at $70-$100K, they won't sell too many.
Well if you could buy one for under 50K it might be an option. The weight of the vehicle highlights the battery density issue for large batteries. We really need a breakthrough in battery density like the solid state batteries that Toyota has been talking about. Unfortunately to this point there is no steak to go with the sizzle.With 200 KWH the Silverado is getting there and would be enough for a lot of guys. Too bad it weighs 8500LB.

At 8500 lbs is this thing classified as an HD vehicle?
