The cold rational left-brain summary is simple. The Renault 5 is an electric supermini, sitting at an impressively good-value part of the price-range curve. Thanks to the UK government's Electric Car Grant, a version with 255 miles of WLTP range can be had for under £24,000, and it's got most mod cons. But of course, the right brain is in charge here. Just look at it. This is a car you desire rather than merely decide upon. Renault has tapped into a seam of happy memory. The original R5 was a brilliant piece of distinctive product design that gave millions of people sunny memories in the simpler times and roads of the 1970s to 1990s. That covers two generations of drivers, and there's another generation younger than that who were rattling round, unbelted, in the back. Of course the 5's pitch isn't wholly novel. You can have a Mini Cooper Electric and an electric Fiat 500 or Grande Panda. Like them, the R5 is more than a slavish visual copy of a sepia-toned memory. Of course you can go modern: there's Hyundai Inster, notably. Or the Peugeot e-208 and Vauxhall Corsa Electric, but unless you twist your dealer's arm you'll pay more for them and come home with a car that’s unlikely to make you feel as bright and cheery. There's also the MG4 and BYD Dolphin, which have more space but nowhere near the feelgood. The decision to re-make one of Renault's 24-carat greatest hits has galvanised everyone in the company to pour their uttermost efforts into it. There are plenty of tales of designers and engineers working most of the way round the clock to perfect it. And when a car has been made by people who love it, it shows.
