> I want, need, have needed for years an electric car. I want 100 Klicks per charge. It only has to do maybe 100 Kph max. OK, so I need to re-buy the batteries every five years or so. I do not want a car that goes 0 to 110 Mph in 3 seconds. That is just stupid. It should cost around 15 grand. Where is that car?
Let's look at some real-world examples -- the Prius can go about 7 miles on battery-only power at 35mph max. Replacement batteries are about $8k. They start at $23k.
Fast forward two years: the Chevy Volt can go 40 miles on battery power. Replacement batteries: ???, but most be more than $8k. They will start (I'm guessing) $40k.
Rewind 12 years: GM's EV-1 was produced for: well, they spent about $1.5B for 1500 cars - that's around $1M each. Higher production numbers: let's guess $100k. Batteries (replaced every 3 years or so - guessing again): $50k. Not close to $15k. GM bet big that they would find a significant battery break-through (the breakthrough that has been "just 5 years away" for the past 25 years). What do you do with 1500 cars that will require a $50k replacement battery pack? Recall them, and shred them.
Toyota's Rav4 EV is a contender. Though battery packs for that vehicle are $26k (so says Wikipedia). I've seen used ones on ebay in reasonable shape for $60k. Except for cost -- this one is a winner for you.
The Aptera has 3 wheels so it can be classified a motorcycle, and not meet all the safety requirements and testing that cars need. (neighborhood cars - max speed of 25mph and another way to avoid being tested as a "real" car - are not included here) It's much lighter and easier to get speed and distance out of the batteries (plus batteries are better today).
Assuredly -- if someone could build a viable EV for $15k, they would, and they would make a killing. Your $15k goal is too low for today's battery technology.
