I've had my XC90 T8 for 6 weeks now and have filled the tank twice

First tank I averaged 38mpg (US gallons)

Second Tank 39.7 (On board computer claimed 42mpg)

I'm now on the third tank and the on board computer is claiming 46 mpg, so I seem to be getting better. I have a 40 mile commute to work, but recently I have started to Plug In and charge at work. Around town the ICE is used sparingly and I get between 50mpg and 150mpg depending on the time between recharging.

recently I have downloaded the app to help find Charging Stations, and will start shopping at those locations.

Wow scaramoucheii, that's outstanding! The T8 is a good fit for you.

Having owned a Prius I'm convinced that if someone really wants to save money on gas they should just get the smallest vehicle possible with the most efficient drive train, the hybrid overhead/payback is less attractive on larger vehicles. In the XC90 range the T6 is probably the sweet spot for most people.

After 4,400 miles our T8's average is 45 mpg Love it :thumbup:

I must be doing something wrong. My battery just depleted and I'm getting 10-15 mpg @ 35-45mph. That just doesn't seem right. Even when coasting a depleted battery only gets me around 22 mpg. If I try to drive anymore conservatively I'll just pull out my bicycle.

Which mode you are driving? If it is not "Power" or "AWD" or "Off road" mode , have it checked by a dealer.

If I'm driving completely local, I'm probably at about 15-18 mpg.
If I'm doing mixed driving or looking at the average for the trip meter, I'd say about 22-23 mpg.
If I'm doing completely highway driving and I'm in eco mode trying to maximize my mpg (aiming to not even touch the brake), I have gotten between 25-33 mpg depending on speed and the flatness of the road.

As always, your mileage may vary.

Something is amiss.

We're close to you (metro DC) and recently completed a round trip to Ottawa, Canada for the Christmas holidays. Started with a full battery leaving DC, and achieved a real 27mpg. That was at a crushing speed of 72-75, in the winter (started around 40 degrees and ended around 20 degrees), with a loaded car. On the return we started with an empty battery, and pushed against strong 30mph winds for much of the drive, and achieved 26mpg. T8, all software updated, 5000 miles.

I'm driving in Pure, always. I suppose that's what I'll have to do. It seems like when I don't have battery left that the car is guzzling gas. I always have the car in ACC or PAII. No issues with the car to date. But that is why I started this post, is because they gave me a loaner and the loaner got much better mpg than my car on ICE.

Also I'm not understanding their auto climate feature. If the car is in auto and the cabin reaches the 77 I have it at, shouldn't the fans slow down? Why do I have to choose fan speed if the car is in auto.

Seconding this. I just drove a shorter trip for the weekend here in the Midwest. Total of about 250 miles and averaged around 26 mpg with speeds hovering between 75 and 80 mph. My overall/lifetime mpg is around 39 mpg since I picked it up at the end of October. It was around 45 to 50 mpg before Winter hit.

I've posted a lot on my T8 experiences elsewhere - you may want to look for some of those posts.

In the first six months or so ownership I easily broke 60 MPG - most of which is a combination of commute, around town and some not that long trips on the Interstate.

After about 14 months and 11,000+ miles I'm at around 42 MPG for the life of the vehicle.

My daily commute is 9 to 10 miles - I charge both at work and at home - and I adjusted my commute to ensure it is 100% electric.

Ok so if I drove from MD to New York, which consists of 95N 295 and the Turnpike, doing 75-80mph on Pilot Assist, what would you forecast my mpg as? Very hypothetical but..

My Fuelly link which I'm using to track as well says my last fill up I did was 40.8MPG.

The last fill up was at 707 miles and I've got 1/4 90 miles left in the tank and am currently on 1060 with the onboard saying I'm doing 38.6MP

My diving is perfect for the hybrid engine. The school run is 5.1 Miles round trip and all my daily driving is well with range and one has a free charging point.

I am not familiar with that area or the distances involved. Terrain and weather conditions are important factors in efficiency, of course. But in the relatively flat area between the southern suburbs of Chicago and southern Wisconsin, on clear roads with no particularly strong winds, I averaged 26.5 mpg according to the data in my trip journal.

I don't know if Pilot Assist is any more efficient than not using it. I would imagine that it's not without adjustments to your target speed. As I recall reading in an article/post from a hypermiler a while back, taking advantage of terrain by slowing down uphill and accelerating downhill can have a significant impact on fuel economy. While not considering myself to be a hypermiler, I do tend to use that strategy and believe it to be more efficient. Pilot Assist cannot take advantage of such a strategy automatically although you can certainly easily adjust its target speed accordingly. Drafting off of larger vehicles is another technique that can be employed but is one that I don't feel comfortable with in many situations.

I made the drive from metro NY to DC, averaged about 26 mph with the flow of traffic, so above 70mph or so, in eco.

Errrm, the point of the XC90 is that it seats seven. That's why it exists. The hybrid/PHEV is not just to save gas for economic reasons, it's also to reduce the emissions (at the very least to the point of production, or better to a renewable/clean energy source)

So is this not normal? This was at 35-40mph. Ultimately if there is an issue, how would I bring that to Volvo?

There's nothing particularly wrong with that display, assuming you've been a bit lead-footed. The mpg you are showing there is instantaneous (or at least for the last few seconds). If you've just accelerated to 35-40mph hard then that's what it'll show, given that you're out of battery. As soon as you hit the cruise control for your 35-40mph then the mpg will increase at that point. Use the "driver performance" graph for detailed information instead.

 

[UnknownUser]

As tillsburg said, that's not the average, that's instantaneous. When accelerating it's normal to have it less than even a couple mpg if you floor it, because in that instant you're killing gas.

Pull up the trip info, you can see either the average since you last reset the trip meter (the TM mpg value) or the automatic trip meter which calculates the average for the miles driven since the last time the engine was off for 4 hours or long, I think (the TA mpg).

 

[goVolvo]

Actually I don't know if in Pure mode the MPG is calculated differently by computer. Essentially Hybrid mode also will use battery first just like Pure mode. Maybe only the time to turn on ICE is different. So I don't know why there is need for Pure mode at all, just to make sure you don't need to use gas for the last several miles to home? I am sure it is useful to some but not really big deal.

OP can try hybrid mode and see what's the MPG number.
