You have NO concept of how electric Cars batteries work... Batteries will maintain nearly all of the torque until empty it is not like Wetcell batteries. ........ My Telsa has just as much speed and torque whether 100% or 20% of battery. That is the beauty of Lith Batts they maintain power down to near zero...
Your post/experience conflicts with nearly everything I've read as well as my own testing with Tesla cells and their output.Just because the battery charge is dropping doesn't mean torque is dropping.
Tesla Model 3 drag times tested by battery %
100% charge = 11.4X
78% charge = 11.65
56% charge = 11.87
25% charge = 12.28
Now, the Model 3 weighs around 4,000 lbs, and using the calculator here:

They estimate running an 11.4 to a 12.2 quarter for a 4k lb car is a difference of 533 HP vs 435 HP (nearly 20% drop in HP). Yes, it's rough math, but 100% unbiased.
One of the many discussions on the Tesla forums of their power/torque dropping as the battery % declines:

Ultimately it comes down to how the Jeep system is engineered, as far as how much overhead it has and how conservative it's tuned. However, I'd bet they're not over engineering it, due to it also having a 2.0 gas engine they're expecting most to use, given the low range, and it will lose power with each % of battery loss (more than the Tesla). Not only that, but probably up to 10% battery capacity with each 30,000 miles driven. We'll see, though! It's at least a step towards something I'd be interested in.
