Cornwall is a long way from anywhere. As someone who comes from the pointy bit of the U.K., I should know. If you’re driving an EV to and from the most south-westerly county of the mainland it’s therefore a very good idea to plan ahead. You’ll need drinks, snacks and, most importantly, a clear plan of where to stop to charge up.
A decent EV is useful too, and the rather excellent Hyundai Ioniq 5 is perfect for the job. It’s not quite a match for the 353-mile Long Range Tesla Model 3, which Tom's Guide Automotive Editor Tom Pritchard drove on the same route recently, but it’s not far off.
