The Kona has the same engine internals as other cars from the group (Kia Niro hybrid & Hyundai Ioniq hybrid) so it’s just more choice on the Scheme, Ioniq for the most efficiency, Kona for the small SUV looks, Niro for the larger luggage space & more legroom for rear passengers.
Having sat in a Kona I like it very much from the drivers seat, having driven the Niro I like that too, however, I’d ideally want the full EV versions of these cars, not the dirty fossil burners.
