Ok, I'll buy that. That's about what - 10 litres of diesel? 2.19 gallons?
700km? That's around 437.5 miles
200 miles per gallon equivalent.
OK even with a power train at 90% instead of 30% efficient that's still pushing 66mpg equivalent.
Especially lugging that much battery around
But how long wail a fast charged battery last?
Before it's lost half its capacity?
I really don't see it.
