Much less.

It says here that the road load for a Metro is nine times as high at a steady 65mph than at 25mph. Also, the faster you discharge a battery, the less energy you can extract from it. So... somewhere around 60 miles? That's enough to get from one side of Buffalo to the other and back. I'd love to have that kind of range.

I'm curious, why did they choose 8320 cylindrical cells instead of a few dozen 60Ah prismatic cells? It seems the latter approach simplifies your battery monitoring/management scheme.
