LOL!
One month ago, when I bought my ZeroS, I had to ride it 300mi from Paris to ALsace. Took me 1.5 days at a cruising speed of about 40mph. This was my calculation to get the best overall trip time, taking into account the very long charging time using the internal 1.1-1.3kW charger.
The GM Bolt is much expected in Europe too, as a game changer, or a potential alternative to the TM3. It will be put on the market under the brand name OPEL Ampera-e, Opel, former (or still) german car maker and part of the GM group, which has been recently sold out to PSA, Peugeot-Citroën, french automotive group. The "Opel" cars are sold in the UK under the "Vauxhall" brand. Complicated marketing!
By now, the best range/cost ratio is owned by the Renault ZOE which is Europe-only. It has a 40kWh battery and a real-world range of 300km (180mi). Unfortunately, in some countries like France, it is sold virtually battery-less with a mandatory battery-rental scheme which make things complicated and costly on the long term. This is the only reason why I did not acquire one. The i-MiEV remains the best possible EV at the "entry-level".
