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

My guess is they designed/finalized the physical pack dimensions early on. You kinda have to if the entire floor, including seat mounts, is the battery itself. Then the new 4680s turned out to be such duds, that they ended up with far less battery capacity (kWh) than planned, with no room for more cells.

There’s also a reason they’re already hyping “Version 3” 4680 cells not long after they started making the first two versions.

Stick a fork in it!

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.

Here is consumption across the "trucks" laid out a little more comprehensively.

Yup. They pretty much boxed themselves in on this one.

Could you brief explained what design constraints Telsa have when creating 4680? Thanks
