There are many electric cars now on the market that will comfortably handle 75 motorway miles. I'm running a Volkswagen e-Golf which I rate highly and, with a bit of restrained driving, can cover 160 miles on a charge. The Hyundai Ioniq Electric is another good choice, officially capable of 174 miles on a charge. If you'd prefer a crossover, the new Kona Electric has a range of up to 300 miles. I'd buy new - the battery technology is progressing so quickly that even a year-old EV won't be capable of travelling as far from a charge. There are some good deals to be had on new EVs too - and you can take advantage of the Government's plug-in car grant.
