It’s not just any old LCD screen, either. Sphero has used a trapezium-shaped screen to perfectly match the shape of McQueen’s windshield from the films. They're fun to drive, but they're also much more likely to break because of the higher crash forces. And they're so fast and substantial that they could cause damage to a child, or property, if in less experienced hands. Find out how each car compares in terms of top speed, run time, durability, ease of use, and how our testers - aged from three years old to 60 - rated each car after driving it on a variety of surfaces. Once he’s charged, he’ll also say his favourite catchphrases like “ka-chow!”. He does this through a speaker within the car, and his mouth moves as he’s talking.

It helps that the car has been voiced by Owen Wilson himself, but there’s also some incredibly smart technology under the hood. Sphero calls it the most advanced remote control car ever made, and it’s difficult to argue with that statement.

There are some really nice features within the app itself though. You can queue up your favourite Lightning McQueen catchphrases and activate them as you’re cruising around your living room. There’s also a mini-game where you work in the pit stop during a race, equipping cars with the right oil and wheel changes within an allotted time. Only logged in Which? members can view the best RC cars for adults below. If you're not a member, you'll only see an alphabetised list of the cars we tested.

We tested some cars we think are too fast for very young children, and in the wrong hands could potentially cause injury or damage. We recruited a mixed aged and mixed gender testing panel to assess each remote control car on how much fun it is to drive and determine which age group the car is suitable for. The panel included two mums, three dads and children aged four, six, 10 and 11. All these on-screen buttons mean you have to constantly look down at the display to see what you’re pressing, so you’re constantly flitting your attention between two things at the same time. If you had a physical controller, you’d be able to just feel these buttons in your hand instead, and not need to look down at the screen. First of all, you need to press a small button to orient the car when it’s facing away from you, just so when you press "up", it goes forward. There are no instructions in the box or on the app to do this though – it’s only because we met with Sphero that we were aware of this.It’s clear, though, that this is a premium item as soon as you open it. The wheels are protected by small plastic clamps, and the accessories slide neatly out of a drawer underneath.
