Kia EV9 review - Boot space, practicality & boot dimensions

“The EV9’s five-metre length pays dividends for passenger space, and there are some neat storage solutions”

5.0 out of 5

Measuring over five metres in length, and with the advantage of a flat floor with no transmission tunnel, Kia has been able to put the EV9’s vast interior space to good use. It’s available as a traditional three-row seven-seater, but also in a more luxurious six-seat layout, – both configurations genuinely allow enough space for adults to sit comfortably. The middle row in the six-seater version has two captain’s chairs capable of rotating to face passengers in the third row, for a pretty unique experience.

There’s lots of legroom and middle-row passengers can move their seats forwards to improve space for those in the rearmost seats. In this configuration, there’s a good amount of space for adults in the third row, although they’ll need to be somewhat agile to access them. Headroom and shoulder room is excellent in the rear of the cabin, although the Volvo XC90’s third row has a touch more kneeroom and a better view out.

Kia has clearly spent a lot of time optimising the cabin for family use, with features such as a large glovebox that pulls outwards instead of dropping down onto the front passenger’s knees. A large central area houses wireless smartphone charging and storage, along with pop-out cupholders. There’s also a pull-out tray and storage cubby for those in the middle row, along with USB ports dotted around the cabin and more cupholders.

Has the Kia EV9 got a big boot?

Even with all seats in use, there’s still a decent 333 litres of boot space – about the same as a supermini offers. Fold the third row down (electrically in some versions) and a huge 828 litres is available, easily beating the 569 litres of an Audi Q8 e-tron. If you need some extra space for shopping or charging cables, the single-motor versions of the EV9 also have 90 litres of storage under the bonnet, shrinking to 52 litres for AWD versions with a front motor.

Is the Kia EV9 a good tow car?

If you plan on towing with your EV9, you’ll certainly want to give the entry-level Air version a swerve. Pick this trim and it’s only rated to tow 900kgs, while the GT-Line trims with four-wheel drive and lots more power can tow 2,500kg. That’s the difference between a small tip run trailer or bike trailer and a full-size caravan, and it beats the Volvo XC90 by 100kg.
