My car is a 2025 Sonata Hybrid, so I'm hoping for upwards of 50mpg. I think I could be happy with anything over 48 due to elevation changes and the occasional "need for speed".
As it turned out, I got 48.4mpg going from Riverbank, CA to Albany, OR so I didn't have to stop for gas in between

. Gotta watch out as most branded stations advertise a cash discounted price and bend you over for 10¢/gallon for credit cards

.
The 70mph stretches didn't help nor did the multiple summits near the border between Oregon and California.
