How to stay cool in your car

An MG ZR is no place to escape the current heatwave

WHAT’S the hottest you’ve ever been? Chances are it’ll be mid-gulp during a particularly brave visit to an Indian restaurant, or during that holiday to Majorca where you and your mates forgot to dab on the suncream.

For me it’s always going to be an assignment that involved watching Ford GT40s powering around the Catalunya circuit – it’s a rotten job, I know – but last weekend very nearly edged it. If you want to ramp up the hottest day of 2017 to extra degrees of stifling discomfort, just chuck a car into the mix.

The one at my disposal was an MG ZR, which you’ll no doubt remember as being a Rover 25 with a bodykit and really stiff suspension. It’s a lairy, chuckable hot hatch in the old-school sense of the phrase, but being a 14-year-old car made on the cheap by MG Rover it has no aircon whatsoever.

So coming back to it after a car show – with it having spent nine unbroken hours in 30 degree sunshine – meant having to take a rather more cautious approach to driving.

For starters it might have been 30 degrees on the outside but on the inside the temperature was probably closer to what you’d find on the Sahara. Putting your hands around the steering wheel felt more like grasping a freshly cooked Cumberland swirl – only minus the oven gloves. The ZR’s also fitted with part-leather seats, which normally add a touch of class to a teenage hatchback but last weekend felt like having two small ovens burning into your shoulders.

The little MG did at least managed to keep its cool in traffic – which is more than I’d be able to say of my MGB in the same scenario – but driving it even for an hour, with every window wound down, was unbearable. It makes me wonder how everyone racing at Le Mans, managed to sit in even hotter climes last weekend and do a bit of racing while they’re at it.

But if you aren’t lucky enough to have air con fitted there are a couple of things you can do. Drive early in the morning or later at night, when it’s cooler. Leave the windows partly open if it’s safe to do so. Make sure your engine coolant’s topped up, and whatever you don’t leave any children, dogs or other vaguely cute things strapped in while you pop to the shops.

Oh, and don’t leave it for nine hours in the baking heat at a car show.
