Even if the Mini EV does offer a range that's a bit lower on the spectrum, they could easily compensate for that with efficient rapid charging. I think this car can beat the Cooper S' 0-60 time of 7.3 seconds.
Outside of the city, I rarely see a Mini. People buying these understand their limitationsI think there are some limitations with range and performance, merely do to the size of the platform they have to work with. Isn't a whole lot of space in that floor for a capable battery pack, and we might have to wait until density can be improved.
