Hyundai has turbos in their Santa Fe and in particular Sonatas for sure since 2011. They all take regular. I’ve driven several Santa Fe turbos and they run just fine on regular.
Adding to this discussion is that I don’t like the hybrid Sonata. CR didn’t like it either.
I’m not big on turbos but they do fine in the marketplace and are not known for self-destructing anytime soon. Eventually, they will likely need to be replaced after a lot of miles roll up on the clock. Trucks use them because they have to. Car turbos are more of a marketing ploy in my opinion.
I’ve got a Subaru Legacy GT turbo and love it, but a lot has to do with the engine geometry (horizontally opposed flat or “Boxer” four), low center of gravity and a great AWD system. Premium gas though, like most gasoline turbos.
