      New 2019 T6 XC90, low MPG numbers

      I've just purchased a 2019 T6 XC90. I've very happy with the purchase, except I'm getting very poor MPGs. First tank MPG only around 16.1, with more than 50% highway driving. Everything is set to ECO mode except steering force. I don't think I'm an aggressive driver.

      What numbers are people getting?

      Our '19 V90cc is getting around 17-18 now that it's colder. Our commute is 50/50 highway/city. Back in the summer I was able to get it closer to 20-21.

      Like you, that's in Eco and non-aggressive driving.

      How many miles have you put on the car?

      In my case nearly 7,500.

      I found that the mileage on my 2016 T6 improved as the engine aged in. Initially my fuel efficiency was closer to yours, but was much improved after 5K miles or so (and I'll be honest, I am an aggressive driver.). I am seeing similar poor mileage on my 2019 T6 with 1k miles, but am confident it will improve.

      PSA: 'Eco' modes don't really work. You're just robbing yourself of power. You're better off learning how to be gentle on the throttle and to avoid braking (ie. 'go with the flow' of traffic)

      OP I don't think your MPG numbers are necessarily out of line. So much depends on traffic, personal habits (lead foot?), climate, terrain, mix of city/hwy. If you really want to find out how your car is doing go on a long road trip.

      On our 2018 the city MPG is rather poor (I'd guess 17) but on a long trip we can easily get 25-30 MPG.

      Are you going off of “TM” MPG numbers or actual mileage-based MPG?
      The TM MPG feature is not necessarily accurate

      I've got a 2017 XC90 Polestar, and have religiously tracked my fuel economy on Fuelly.com since the day I got the car. That means I record mileage and gallons at each fill. I have over 30,000 miles on it, and according to the Fuelly record keeping, I'm averaging 23.1 mpg with 47% city and 52% highway. My high mpg was 28.1 and my low was 16.7. I never rely on the in car computer as it is always 1.5 to 2 mpg high. Most of the time I drive in Econo mode although when I want to play I'll put it in dynamic, although that happens infrequently.

      My car is brand new, 200 miles or so now. I'm in sunny socal so climate shouldn't be a big factor. I've never considered MPG as a deciding factor when buying a car, but 16 mpg combined is quite a bit off of the advertised. Will drive another tank and probably talk to a dealer if its still this low.

      btw, I'm just going with the number from trip computer. Didn't actually measure it at gas fill up.

      Volvo’s ECO mode does actually make a difference. It allows the car to coast rather than engine braking and it optimizes the climate control to use less fuel. It also softens your throttle response, which is the same as the driver “being gentle” on the throttle. It doesn’t turn your car into a hybrid, but it does help to get a few more MPGs. I’ve had good results using it on road trips. I doubt it would help much with city driving.

      FYI, after about 30K miles, we are getting 21-22 mpg average on our T6 XC90. Probably 30% city driving.

      MPG is low in city driving with uphill and downhills.

      Driving an XC60 and getting about 22 mpg with my T6. I'd probably guess 80/20 city/highway driving, but with only 2700 miles on it. In ECO mode most of the time as I'm usually in stop and go traffic. I also use pilot assist too, not sure if that makes a difference.

      I have a new 2019 T6 XC90 Inscription I added Polestar and I avg 13.1 mpg. I have a lead foot and I like extra pull when I hit the gas.

      I’m getting about 15.5 mpg with most city driving. 2019 T6. It seems low to me too so I was thinking about asking the same question on this forum.

      Consumer Reports testing showed 14 mpg for city driving with the T6 XC90. So if you mostly do city driving and are getting around 15 mpg, that makes sense. Their highway driving results showed 28 mpg.

      Thanks folks. I guess their EPA combined MPG is just way off (16 vs 22). Not too happy about that. It is a a first for me as all my previous cars (honda/toyota/bmw) driven on the same daily route had always met/exceeded their EPA numbers.

      How do you like the polestar? I tried dynamic mode on my volvo and I hated it. I don't like throttle curves where the car is jumpy for light paddle input then run out of steam when you floor it. Good sports cars always have linear throttle based on my experience (bmw/tesla). ie, you when tap on throttle it moves gently, then progressively faster when you give more input.

      60k miles on our 2016 and I use Fuelly as well. We almost always average over 20mpg at fill up regardless of driving type.

      It's exactly what I was looking for. On the non Polestar I did't like the lag now it has no lag and I like how it pulls quicker. The milage not so great due to me having fun

      Several factors. Winter gas, new motor being the biggest. The EPA figure is also based on 91.. so if you're running less than that it can affect fuel economy. The computers on a direct injection motor should make the economy figure spot on.

      I run 93 octane from Costco. Looking at Fuelly, I have gotten an average of 18.8 MPG over 23 fill ups. I don’t drive the car hard (2019 XC90 T6 Momentum), but I just chalk the not stellar gas mileage up to it being a really heavy SUV.

      I just purchased a 2020 XC90 T5 AWD. There's probably ~400 miles on the odometer and i'm averaging around 18mpg with city/highway driving combined. I try to use eco mode whenever I can.

      2016 T6 .. only had it for a few months, but via fuelly, averaging 23.1. I like some of what ECO mode does, but I'm already easy on the pedal, so ECO mode is highly problematic when the occasional burst of speed is necessary and you need to stomp down. -- I might set it as my default mode if that was freaking possible .. so I just leave it in Comfort.

      You are using a petrol engine in a heavy car with a huge front surface. I think your fuel consumption is pretty normal.
