2018 Prius Prime finally showing actual MPG?

The odds are slim to none. The only reason I could think of would be if there was some other reason to update that part of the software and adding that feature made Toyota's software version maintenance easier & less expensive.

I cannot think of any other way Toyota could profit from making such a change.

 

No profit opportunity, but still opportunity.

You can have the FOB updated, upon request. I did for the "open all windows" feature.

Toyota updated the buttons on the steering-wheel in the past, providing a software update just for driver convenience.

 

I just looked at my Gen 4. I suspect it would need a different speedometer display, much like the early Gen 4 needed to switch to Km. there does not look like any space for a digit wider than 1.

 

I want this. I have been pinned on 199.9 for a while.

 

I've been pinned on 199.9 per trip A on a tank of gas, so I just changed the ODO to total miles on car and voila 115.9 mpg for 4500 miles.

 

Who would buy a 18 when the 17 is the same car but so much cheaper

 

I have a ScanGauge2 and it seems to show the actual MPG. So the computer may have the info but only displays up to 199.9.

 

Diminishing returns... there simply isn't much benefit of values over 200 MPG, especially when margin-of-error is considered.

 

Sure hope so

Fill my tank every 500 miles.
Last time I used 1.5 gallons of fuel.
That's about 348 MPG.

 

agree, the actual calculated has never been accurate on a Prius IMO.

 

I've never really understood why anyone cares about the >199 mpg readout. When you're driving mixed EV/gas miles, it's pretty much meaningless, as it doesn't factor in the $$$'s/carbon contributed by the EV/charging component.

The only time my mpg readout means anything is when I'm running in pure HV mode. If I reset the tripmeter, and run in HV mode, I get a true mpg indication. But I often forget to switch back to HV from default EV mode after a stop, and then my mpg calculation is toast. I really wish the HV/EV mode selector was persistent.

Which is why I don't bother running Fuelly stats with my Prime - meaningless...
