We are close on the range. I have spoken with my gnomes and they agree that is already their if you will it's the next beach head is charge times. 12 to 15 minutes with Solid State Batteries which will supposedly be here 2025 and after.
Look for the latest press releases from QuantumScape and Solid Power. Solid Power's latest Release w/ diagrams denote 300 mile range, 15 to 20 minute charge times (depending on the Cathode) with a reduction in Mass and Pac Size of 44% and 46% respectively. That also coincides with the Ford Video Press briefing given by the head of engineering Hau Tia-Tang. Solid Power also noted cost of the pac goes down almost $4000. It is a trade off at that point, more weight and pac size to reach the 400 miles, unless other breakthroughs in Watt's/Kg density occur that is compatible with the architecture and chemistry's they are using.
We shall see.... heard this for decades now...
Just like Uber arrogantly thought self driving cars we’re almost here too...
These 80/20 90/10 problems abound... people foolishly think because they push through the first 80 to 90% relatively quickly they think the last 10-20% are east, when in fact they account for 80-90% of the overall effort...
Like I have said, I think Evtol is more likely to mainstream before fully electric vehicles...
Time will tell
