aerodynamics helps Ioniq a lot, not much to Kona/Niro. As for efficiency of the drivetrain, if you took electrical engineering courses - being electric does not mean being efficient, it is all function of the design and cost. Then comes integration between subsystems. Hyundai/Kia offers heat pump, that is integrated into battery and HVAC loops so it helps with low temp in the winter when all other EV suffers the most. Tesla also wastes a lot of power on computers to keep it running and devours battery even while turned off (0.5-1 kW/h depending what features are on or off), Hyundai/Kia are more efficient in this area by far - it hardly looses any charge over a week, while Tesla looses 2-5% daily just to check once a day battery SOC over the phone.
As for battery - tiny temp sensor would bring perfectly healthy battery to a screeching halt and render it inoperable, cell degradation is non-existent on LG batteries, 2016 Ioniq/Soul EV owners did not detect any degradation after 3 years (nobody would dare to say it about Leaf batteries or even Tesla ones). Also unlike most EV batteries at least Soul/Ioniq EV batteries are serviceable, could not say about Kona/Niro yet. We do have SoulEVSpy android app to check on battery and other internals of the car, so claims are not just made on consumer assessment or guesses.
