Cruising Range City poor?

How do you figure that?

Don't assume that is figured with the claimed fuel tank capacity, because it isn't. Several gallons are set aside as safety margin, and not counted towards the displayed range. To get a "distance to empty" of 416 miles, its recent history must be getting over 40 mpg.

The true way to compute MPG is to compute it from fuel refills. Keep a fuel / odometer log.

Short of that, use the trip odometer MPG display, and remember that it is a bit "optimistic". E.g. subtract 5%, give or take several %.

Notice that I added a link to a fuel economy page after you first read it.

 

well, if you're getting good mileage, there may not be much more you can do.

one major item on gen 3 is the egr circuit

 

It's dead, you should sell it to me for cheap... jk! Maybe air up tires, check the HV battery health with the Dr. Prius life expectancy test and go from there. Also always drive far enough to warm up the engine fully and no short trips if possible.

 

Try cleaning EGR circuit and intake manifold..

17” tires and “lots of stop and go” both likely factors.

This is calculated mpg?

I second the EGR cleaning, not so much for mpg, but for engine preservation. It’s overdue. See first two links in my signature (on a phone turn it landscape to see signature).
