A roof box on the Kia EV6 is fine as long as the box, its contents, the rack and the attachments stay under the roof-load rating, and an empty box alone weighs 15 to 25 kg. Choose a fit configurator that lists the EV6 generation, not just the model name, and locking towers are worth the few pounds extra.

What to look for on the listing
- Fit configurator that lists your Kia EV6 generation - not just the model name.
- Locking towers (few pounds extra, stop the whole rack walking off).
- Torque wrench in the fit kit (over-tightening cracks the door frame on clamp-on kits).
- Cross-bar length: 108-127 cm is typical for a car this size.
Frequently asked questions
Can I add a roof box to the Kia EV6?
Yes provided the box + contents + rack + attachments stay under the roof-load rating. Empty boxes weigh 15-25 kg on their own.
Does a roof rack hurt fuel economy?
Empty, around 5% penalty at motorway speed; loaded, more. Aero bars minimise the empty penalty. Remove the rack for long motorway runs when nothing is on top.
