There are now quite a few videos about the new Smart #2 (pronounced "hashtag two" it seems, whereas the petrol Smart that most people know was called the "Fortwo"), for example this one from What Car:
The range is not officially confirmed but they have a "target" of 180 miles. The video says charging is capped at 65 kWh and will take 20 minutes to charge from 10-80% at that speed. So 20 minutes charge to go 127 miles. Is that good? The video says this is good compared to the Honda Super N and Renault Twingo.
That's likely to mean a circa 2 hour trip should be doable without charging (in the winter, rough ballpark of usable milage being 55% of quoted range) and you'll then need 20 minutes to do circa 3.25 hours of driving.
However, as I highlight, typically most people would be best to stop for a break in that time anyway (even if it's just a loo break) and from parked to back to the car can easily be 10 minutes anyway (especially at larger motorway services).
Also, someone owning such a car probably are the reason we can do 6 return trips of 240 miles each way a year and the average number of trips of over 50 miles is lower than that.
That's not to say they won't do them, it's just that it'll be fairly unusual, as that would likely be the small run around with a larger car for other trips.
If its £13,000 new (even £14,000) that's going to be very much in the price range which could mean £120/month lease costs and so a good entry level EV for commuting up to 30 miles a day (might just get away with charging twice a week, or 5 times a fortnight).
That would compare with a fuel bill of around £95 a month, and so the cost of say £25 a month plus £1,600 up front, would mean a cost of £2,500 for 3 years.
Even allowing for some resale value that's quite a cheap car to buy second hand as an alternative and finding one where you do well and there's no major maintenance needed.
