Is there a way to tell how much of the vehicle's total mileage is on ICE and how much on battery? Would be good info to know when buying a used one or selling.

No, there is no direct way to tell.
Yes, you can calculate it, approximately.

Look at the overall MPG displayed on Sensus screen in Car status app, say it is 35mpg.
Then you know that means total_distance_traveled = fuel_consumed * 35mpg
Now make a guess of overall pure ICE mpg, say 20mpg (or up to 28mpg, just a guess, because we really don't know),
then the distance with ICE on is fuel_consumed * 20mpg.
So distance on ICE / total distance = 20 / 35.
distance on battery / total distance = (1 - 20 / 35)

If a car is never charged, then the overall mpg number would be about 20mpg.
If a car is mostly on battery and uses little fuel, then the overall number would be about 50mpg, or even 100mpg :)

I've been wondering about this myself. I have 21K miles on my 2018 T8. Using 28 MPG (which is what we got driving 4,000 miles in Europe when we picked it up OSD and drove it without charging for 3 weeks) I calculate that almost 50% of my 17K total US miles were on electric only. We drive almost 100% electric when not traveling out of the area. This means that the car has 12.5K ICE miles and 8.5 electric. Based on my driving patterns, this will eventually be over 50% electric overall. I track all of my miles on Fuelly and the last fill up was 109.2 MPG (961 miles on 8.8 gals.). My overall Fuelly mileage in the US is 54.1 MPG on 17K miles.

I suspect that somewhere in the car's computer system there is a value that represents the total hours on the ICE. This would be an interesting number to know as it would a fair representation of normal wear on the ICE and it's components/drivetrain.

Interesting topic. Next time I have a T8 plugged in I'll dig around to see if I can find a parameter that shows this info.

You can get an approximate breakdown of mileage on gas and electric by creating a report from the driving journal on Volvo on Call.

Thank you, Red. That is very helpful.

Where is mileage at in the Car Status app? You can see it in Driver Performance, but that is easily reset.

Anyway, there is another mpg number in VoC app, seems not able to be reset.

Sorry, was that the answer to my question? Where is it at in Car Status?
I don't have the car with me, can't give you an answer.
If you see all of them can be reset easily then there is no lifetime MPG number.

That's exactly what I have done in Excel. I update it every month with the most current Volvo App trip data and add in the Fuelly info on MPG. It's interesting to see how much electricity regen you get. I have integrated the data from my electric bill to get a more complete picture of actual total costs to see if in fact there is any real dollar savings when considering the cost of electricity to charge the car. The verdict after 17 months and 21K miles is that it is marginally cheaper than gas only. I live in MA and we have the 4th highest electricity rate in the country at an avg of $.25/KwH. Charging in TX would cost half as much to charge.

One reason I bought a 2018 Panamera E-Hybrid (Porsche's PHEV) last year, after having spent many hours (over half a year) test-driving all of Volvo's T8 PHEVs, was the superior display of electric vs. ICE stats (single trip as well as continuous since new); see attached screen shot of my Panamera's dash instrument panel (hours and mileage on right side are for "zero emissions" driving). I wish that Volvo would put much more useful info in their screens -- including the permanent tachometer that Porsche uses in all its PHEVs. (Much greater battery range was also a huge factor -- 50-75 percent greater all-electric range in the Panamera over the Volvo T8s.)

I download and do a monthly summary also and arrived at the same conclusion you did regarding cost effectiveness. The area I live in (Carlsbad, CA) has average tier 1 rates of .29 kwh. I could go to a time of use plan for lower rate but lose advantages of my grandfathered (solar) plan.

Tech....anything further on this? Would be interesting to compare engine hours vs mileage on a T8 vehicle to a non-T8

In fairness, I don't think Volvo positions any vehicle to compete with the Panamera. It's $30-40K more expensive than Volvo's top offering.

I'm a big fan of head-up displays to get the most important regular information in front of you. The Panamara display seems like an absolute onslaught of data that I suspect some of which would be as effective in a center console.
