I don't doubt your experience, but Hyudai-Kia has always marketed Hyudai as the higher-end car. Take that quote from Automotive Reports, combine it with this from this 2013 Forbes article:

Of the two Korean brands, Hyundai has been more upscale. Hyundai offers the Genesus [(base price $35,200)] and Equus [(base price $61,000)] luxury cars, which Kia's tops out with the new Kia Cadenza - the Kia version of the Hyundai Azera. Kia's image is more affordable, youthful, and a little sporty.

Hyundai offers five models higher on the luxury scale than the Cadenza, topping out with the Equus.

Kia may now compete, or even exceed, Hyundai at the lower end or even lower middle, but Hyudai is considered Hyundai-Kia's upscale brand.

Should be “Hyundai” instead of “Hyudai” throughout.
