I'm betting on the tri motor which is supposed to be rated 500 mi to at least get 300 mile. Hope I won't LOSE AGAIN. To get 300 miles against any factor thrown your way is comfortable
Have a M3P (300mi rated range). The way I drive it - mostly 85mph freeway I use 50% of my battery (leave at 80-85% charge, get home around 35-40%) on a 100 mi round trip to / from work in Denver...so 200 mi car (max) on long distance trips with 75+mph freeways. Also have a CT Tri reservation..I think 300mi useful range is probable for most worst case scenarios excluding towing.

Do we know if Tesla currently "limiting" the total utilization of the 4680 packs as they dial in efficiencies and develop a deeper knowledge of the chemistry/geometry pairing? I know they did this with the Model S battery in the beginning. If they are, in fact, holding back some of the capacity of the 4680 packs, what we know about the range / cell could be very conservative.

We got similar mileage because if I drove 90 mi round trip with my Model 3 LR, I used about 40%. If I drove 170 mi r-trip, I used 80%. For EPA rated 330 mi, I only got an effective 200 to 210 mi fully charged on the terrain similar to yours In Nevada. Practically, I'm only getting 65% efficiency from how it was advertised. (During my first discovery of this deficiency, I got mad and disgruntled. I felt it was dishonest. Considering negative mileage factors shouldn't be 35% reduction, just practically too high.) Therefore, to use the same logic, 500 mi should net us 325 miles. I can live with that because for long trips usually we stop to eat or restroom every 200 to 250 miles. My issue is I believe I'm in the middle of the pack in the order list. Actually, I still have to convert my order from dual to tri motor. If I don't get my order by the end of 2025, I'll look for an alternative probably the very reliable Toyota. BMW might price me out.

Seeing all the wrong units here makes my head hurt

kWh - Energy, pack size

kW - Power

I may be the one or one of those using the wrong units to hurt your head. We all want to be able to know everything if possible but we can tolerate mistakes. All I care is I bought the CT with the right battery pack that can go 500 miles and hopefully reach a destination of 300 real-world miles on a full charge. The older we are, the more tolerant and pragmatic we become.

It will be a long while before we worry about demands. All I care is I get what I like and they don't have to buy what they don't like. I believe that other brands will imitate the CT instead of the other way around. I could be wrong too.

Everyone is currently speculating on recent density.

What actually capacity/density does the 4680 need to achieve in order to fulfill its promise of 500 miles ?

_____________________________________

Goodness, ChatGPT come on down !!! But is the answer close ?


To determine the required energy density for the 4680 battery cells to fulfill the promise of a 500-mile range, we need to make some assumptions and calculations.

Energy Density = Battery Capacity / Battery Volume

First, let's assume a specific energy density value in watt-hours per liter (Wh/L) that the 4680 battery cells need to achieve. This value will vary based on the specific chemistry and design of the battery, as well as the desired performance and safety requirements. For this estimation, let's assume a specific energy density of 350 Wh/L.

Next, we need to calculate the required battery volume for a 125 kWh capacity battery:

Battery Volume = Battery Capacity / Energy Density

Battery Volume = 125,000 Wh / (350 Wh/L) ā‰ˆ 357.14 L

So, in order to fulfill the promise of a 500-mile range, the 4680 battery cells would need to achieve an energy density that allows for a battery volume of approximately 357.14 liters.
A fairly reliable source told me Texas is producing their gen 2 cells and thatā€™s what the Cybertruck will ship with.

We donā€™t have much info on those cells so hard to say where density will land.
