I don’t know where else to go for this. Hoping someone can provide some insight. I’m averaging 53.2 mpg in my 2007 Prius. No mods.

My question is, Is this above average or below average for a hypermiler. I practice as many hypermiler principles as possible.
In the winter I get about 45-47mpg and now that it’s warmer, 53.7. I get that warmer air is more fuel efficient, so no concern there.

It’s just an old car. And I’m wondering if anyone can tell me if I could do better?

Also, if I am getting this with 2007 Prius and 200k miles, what could I get with a later model and less miles.

Lastly, when I compare the 2007 to later models, it seems like the 2007 is right on par with the mpg of the newer models. Am I way off?
