For Renault 5, see Mini, Fiat 500 and Volkswagen Beetle: rebooted retro versions of once dearly loved old snotters. Although I’m not sure the 5 was ever quite as loved as the Renault 4.

Still, 5 it is. Which is great: maybe if the Zoe had always looked like this, more people would have bought one. There are retro hints to the new EV, but if one really wanted to do a retro Renault, wouldn’t the impossibly pretty little 4CV be a better bet?

I don’t think so, for one good reason: the 1970s, the decade of the 5’s birth, is currently ‘peak retro’. And peak retro matters. Revive a lovely old car too soon and it will still just be in the naff phase that its decade represents. Nobody is about to make a retro variant of a 1990s hatchback. Revive a car too late, though, and it has passed into a too-classic phase.

Four or five decades after an icon’s launch is the perfect time for revival. The Goldilocks zone for nostalgia.

As with the 5, then, there was the Mini. It was introduced in 1959 and reinvented in 2000, 41 years later.

The 500 was launched in 1957 and the new 500, so popular it remains on sale now, came 50 years later, in 2007.

The Beetle was designed in the late 1930s, it’s true, but proper production didn’t begin until 1945, and it wasn’t made solely for civilians until 1947. And its replacement? It was first seen as a concept in 1994 and production began in 1997, 50 years after that.

Peak retro, then, is like a mid-life crisis in automotive form: the cars are desperate to reinvent themselves when they hit their mid-forties.

Which is great news for the 5 right now, although less so for the 1947 4CV, whose time has probably passed. Likewise a car whose lack of a retro revival I’ve always pondered: the Citroën 2CV, which arrived in 1949 so is presumably now past it. That’s a shame in a way; a pared-back electric 2CV could be very of our time.
