If I was being harsh I would say the Ampera was made pointless by the BMW i3 REX. Both 4 seat cars; but the Ampera only has 14 mile range and woefully slow 16 Amp only charging speed BUT the perfect vehicle for the travelling salesman wanting to do their bit for the green lobby.
Interesting point of view. So, if I understand you correctly, are you saying that there is no point in different styling, size, performance, manufacturer? Would you have us all driving one car? Sounds rather like old-style Russia!
I can accept that for you and for many the i3 wins hands down and I would never argue with that... that is your choice. But to say it is pointless is just not true.
Take me for instance... I wouldn't have an i3 over an Ampera. I much prefer the Ampera style both inside and out. The EV range is 40-50 miles real-world not the 15 your claim. That is perfectly adequate for most daily use. It doesn't need rapid charge because long trips are done using petrol. The killer for me is that the Ampera has a full 1400cc generator that can hold full performance regardless of circumstances even with the battery flat. There is less compromise in performance.
They are quite different beasts and they will appeals to a different group of people.
