Hi, could someone please explain how the T8 works.
My understanding is ICE drives front wheel. Electric motors drives rear. Making 4wd when both working in conjunction.
What happenes when the battery is depleted?
Is it then just Fwd or does the engine act as a generator too charging batteries to drive rear wheels if 4wd is needed?
I’m guessing if this is the case fuel economy will be severely compromised as a result.
We are looking for a Xc90 and on paper the T8 would work better over the other engine options, but also slightly concerned about the reliability of the electric motor.
Thanks

Engine can act as a generator.
The rest you're also correct on
We've done 1500 miles in ours now and we're averaging 120mpg (plus, of course, whatever the electric is costing us).
We reliably get 30 miles from a full charge. Often 36 or so. Only seen over 40 indicated once.
Takes 4 hours or so on my EV quick charger to go from 0-100%. More like 8 on the 3 pin charger that comes with it.
The one regular journey we've yet to do is a 400 mile round trip. I suspect this will dent the 120mpg markedly. (We were seeing over 250mpg until my OH needed to do around 100 miles in one day last week).
OH loves the car. It's our 3rd XC90 so familiarity helps, plus it's a very high quality place to sit. Air suspension works well, sound deadening glass does too (Ultimate spec). So no issues with it at all. And I still rate them extremely highly as a family wagon. But......
IMO, unless you need to tow regularly and a reasonable distance, I think a full EV is a better proposition.
The only real contender is the Kia EV9 at present. If they'd been out longer/were prepared to cut a better deal, we'd likely have bought one I think. Not quite up to the same quality standard... But for the majority of use cases it's a better option.
Also IMO, if the EX90 ever sees the light of day, it's too expensive.

One thing to be aware of OP is that unless you're getting new/next to new the larger capacity batteries haven’t been in too long (Google will confirm).The rest you're also correct on

The first gen T8’s will get ~23 miles indicated range on full EV, I have the XC60 so expect the XC90 is getting high teens. I was pleasantly surprised when Volvo started doing a larger battery PHEV as I thought with the ever-increasing amount of EV’s manufactures wouldn’t bother. I would say 95% of out journeys within pure EV range, school run, shops etc. I’ve had it >3 years and getting a combined 60 MPG, I previously had the T5 which is effectively the same engine minus the battery and got 27 MPG. What I’ve never done is the sums to see what the difference in is taking into account increased purchased price of PHEV vs Petrol or Diesel minus fuel savings. I would hardly use fuel at all if I got a real world 40 miles EV range, when we do go outside of that it tends to be 250+ miles visiting family so for us the PHEV is a good compromise for now.
I get 24 miles on a battery charge. Pretty much constantly. I had a V90D5 and realised from the trip log that 95% of my journeys could be done on a battery (11.8KW). I find it very economical (don't forget to add in the cost of the electricity)
Last long drive, last week, was 150 miles, one charge, and rest on petrol = 52.7mpg - journey was busy M1 with stop start traffic Leeds and back.
I tend to use EV first the ICE, rather than hybrid with battery switching in and out........is that optimal?
For a big car and six occupants that's pretty good. I pay 7p per kWh which makes a difference.

I've got an XC40 T5 plug-in hybrid. I guess it's a similar setup, but with the electric motor sharing drive to the front wheels.
I just leave it in Hybrid drive mode, where it will run in battery mode, firing up the engine if I floor the pedal.
On longer journeys, I use the "battery hold" feature on faster roads to force it to use the petrol engine. In town, I turn it off again, and run on the battery.
The battery never goes flat - around 20% of the capacity is held in reserve for stop/start driving, or where full power is needed.
Even when the "battery hold" function is used, the car will crawl in traffic on the battery.
Range is shown as 24 miles. This is achievable in mild weather with a bit of restraint. Driving faster, in winter, I get around 20 miles.
On a 50 mile round trip, I get better than 80mpg (plus 80p of electricity).
I've done just over 1200 miles since I filled the 50 litre tank. Trip computer says 80 miles of petrol range left, so I should be able to break 1500 miles on 11 gallons of petrol and less than £40 of electricity - cost equivalent of nearly 90mpg.
It probably doesn't save me any money, if you include the cost of purchase/depreciation, over a 2 litre petrol version, but it's faster and nice to drive.
