Best car accessories 2024: car tech you never knew you needed

From dash cams to key locators, we’ve put together a list of the best car accessories for your wheels

A man driving along a road with the Chris digital assistant screen attached to his windscreen – one of the best car accessories

This isn’t going to be a list of Pimp My Ride-worthy supersonic sound systems, hot tubs in the back of the truck, aquariums, or even chandeliers, but a practical list of all the car accessories that may actually improve your driving experience.

From the best dash cams that will prove your innocence in an accident to wireless Bluetooth transmitters for car sound systems that predate smartphone connectivity, the car accessory market is certainly a variable one.

We've also got the best sat nav and the best car phone holder, for those really looking to upgrade their car cabin.

But before we get into the cool gadgetry, there’s one necessary item that clinches the top spot. Dog hair, crisp crumbs, mud, hairpins and the odd penny coin; by the end of the month, your car probably looks like a detritus dumping ground. That means the clever and convenient Dyson V6 Car & Boat is a no-brainer when it comes to ‘need to buy’ car accessories.

The others? We’ll leave the ‘need to buy’ decision up to you – they are all pretty cool, though.

It's wonderfully small, but there's a sizeable digital display that tells you everything you need to know in terms of setting pressures.

You also get the benefit of an internal battery, which in our experience seems to have a reassuringly long life before you need to recharge it. A USB power port is handy if your phone dies too, while there's an LED light built in if you're stranded after dark. Granted, it's pricer than many footpumps, but the quality is obvious. Better still, it makes light work of inflating things, from car and bike tyres through to small boats and inflatable kids toys.
