There are two sets of ISOFIX points in the rear, plus another set on the front passenger seat, while top-spec models have accessories such as floor mats and a rubber boot liner as part of their standard-kit list.

Seats & passenger space
The Atto 3 uses a platform designed specifically for electric cars, which has numerous benefits, maximising passenger space in particular. For instance, there’s a completely flat floor across the back seats, so there’s decent legroom behind its large front seats.
Overall, it’s very spacious inside, given the Atto 3’s footprint, and there’s room on board for five six-footers, even with the standard panoramic glass roof fitted. However, we did find that the rear seat bases are set a little low, so under-thigh support could be better.
Boot space
The Atto 3 features a 440-litre boot, which is a decent size, but doesn’t quite outclass the Kia Niro EV (475 litres), or the Hyundai Kona Electric (466 litres). The location of the car’s battery doesn’t compromise space, so there’s a deep hidden compartment underneath, plus there’s a level load lip. However, there is no ‘frunk’ or additional storage space under the bonnet.
The 60:40-split rear seats also don’t fold entirely flat, but there’s no step in the floor, and 1,340 litres of space is on offer with the rear bench folded down.
Towing
The Atto 3 has an unbraked towing capacity of 750kg, with the braked figure not currently available. Kia and Hyundai quote the same number for the maximum braked trailer weight of the Niro EV and Kona Electric.

- Best buy: BYD Atto 3 Comfort
There isn’t much of a decision to be made when it comes to the Atto 3, because there’s only a single powertrain and two trim levels to choose from. Paying an extra £2,000 for ventilated seats, a power tailgate and a slightly bigger infotainment screen is going to be down to personal choice, but we think the generous Comfort specification will be sufficient for most needs.
BYD Atto 3 alternatives
The Kia Niro EV and Hyundai Kona Electric are the most obvious rivals to the Atto 3, with higher-specification models similarly priced. Some buyers might also look to the extra space and practicality of entry-level Volkswagen ID.4 or Skoda Enyaq versions.
