IMO the i3 range extender has the opposite problem - petrol does not extend the range enough. I do not believe the i3 would be a great car to do a long journey as you would still need to stop and potentially put in very expensive motorway petrol. That and the small boot makes me think BMW are marketing it as a city and near-to-city car. Of course the extra-cost plan that allows the swap with a ICE BMW helps, but that might not be practical for the "I have to go to Newcastle tomorrow for a meeting" scenario... I actually think the i3 range extender competes more with the Leaf than the Ampera as it can go further with a full battery and tank. Of course these are just my thought and others are more than welcome to disagree
