'22 model year fuel economy seems subpar

There are a huge amount of variables when it comes to fuel consumption! Weather, Speed, Terrain, even passenger Weight! (I once sold a car that gave me 40 mpg to my brother who out weighed me by 100 pounds and the best he ever got was 25 mpg! But then again, he went through a set of brand new brakes in less than 5000 miles too!)
My ‘22 XLE gets ~30 % less mileage at US Interstate speeds than at 55 mph. It also gets ~ 50 mpg during northern winter months and has just jumped to ~ 65 mpg with the warmer temperatures.
I have a 10 mile drive to my dealership that I can choose a fairly level route or a route that as some significant hills. Going to the dealership the hills can be in my favor and I can get 75+, coming back on that same route, drops it to 50 or so; the more flat route I get 65 either way unless I decide I am in a hurry, so I drive 65 instead of 55 mph, in which case I get around 55 mpg.
Get the idea?

 

Well said.
My ‘22, in arid climate CA, is showing 57.8 mpg since purchased. Now with 2800 miles on the odometer.
I have it set in ECO mode & drive conservatively on freeway and around town.
I’ve noticed that Car drives in (auto) EV mode much more often in my Gen4 vs my ‘09 Gen2.
For comparison, driving similarly, my ‘09 rarely exceeded 46 mpg average between normal 15-20k odometer resets.
So for me…the Gen4 performs much much better than the Gen2.
