I wonder if the 1.6t cars from Hyundai and Kia do this as well but just not as a published thing like they do in the Elantra N owners manual. The pictures below are from the Elantra N owners manual.

I wondered the same thing. I just picked up my '23 GT2 Monday and I'm about at the end of my first tank, which I'm sure is 87 as the dealer filled it up. I definitely plan on running 93 the majority of the time, as I've had to run it in all my other vehicles over the past 7-8 years, so I'm use to that bill. Have you tried it yet? If so, what's your thoughts?
I am not sure what to think, this powertrain is so finicky to weather conditions, temp, humidity, air density etc. I swear my car is a woman since I never know what to expect for power, each day is a new surprise. I just went cheap on the last tank of fuel and put 87 in, I don't think it has ever felt this strong. Is it weather or fuel or is my ECU really an "artificial intelligence" that has good and bad days?
Maybe a woman AI?
