      New XC60-poor fuel efficiency

      Hi. First post. Sorry if I do it wrong.
      2019 XC60 T6 AWD Momentum. Mostly city driving. Alot of 4 way stops. Stop and Go on major roads.
      But gas mileage is worse than I'd expect. 13-15 US mpg / 16-18 L/100 km.
      Is this expected (even though its far off the posted stats?). Or is there something not tuned right? Dealer non-commital.
      Tire pressure came at 40 psi. thinking of adding a few lbs to see if better, but doubt that's it.
      (actually surprised didn't come at 36 ish).
      Was thinking of an XC40 for second vehicle, but not if this is how things go.
      Thanks for any insight folks.

      Try a long trip of 2 hours and see. Slow traffic is the worst thing for turbo engine and heavy cars. I commute on city street and would buy hybrid cars going forward. XC40 PHEV will be wonderful for me.

      I average between 16-17 mpg. Picking it up and driving it home was the first (and best overall) sustained trip at 25 mpg. I would expect that as it gets broken in that you would see better mpg. I just passed 7000 miles. ¯\_(ツ)_/¯

      I do about 90% city travel and i get around 20mpg. Yours seems a bit low, maybe try and drive in Eco mode to see if that makes a difference?

      My city driving averages 21.7mpg, recently read a post where it said that MPG started to increase after 18k on the odometer. I'm just over 17 so will see what happens

      In the summertime, I've driven thousands of miles cross country with no charging at all on my T8 and the worst I ever got was 26.8 mpg.
      In the winter, the worst I ever got was 21.6, also with no charging. So even though you would expect somewhat better mileage with the PHEV, I think the OP's issue is mainly related to the stop & go city driving.

      It is exact for daily stop and go traffic that I recommend PHEV. Don't like to sit in ICE while burning gas.

      How many miles on your new xc60?

      When I first pick up mine T6. The mileages was horrible. I thought the reading was wrong.
      Now my xc60 T6 has around 800 miles.
      The gas miles has improved a lot more.

      Gotta wait til broken in and you will see the true mpg.
      Look at image, my first 59miles only 11.2 mpg

      PHEV would be better for you

      With that kind of driving, the ICE in this car is not great, especially with a heavy foot. My commute is 13 rural miles each way and I can do the whole thing (barely) on one charge in 2018 T8 Inscription with 8k. I doubt I’ve spent more than $200 for gas since buying it, but unless I’m showing off Power mode to a friend driving like an idiot or doing a road trip, the engine rarely fires up except, of course, in cold months.

      The belief that new vehicle fuel economy improves over time was largely true for older vehicles, but completely unfounded for modern vehicles (circa 2005+). It's a myth told by baby boomers.

      Modern vehicles have lower internal friction, primarily from reduced piston ring tension and enlarged valve guides. This means there's significantly less engine "break-in" needed because the friction is already minimized (less metal surface to "seat").

      It's also why OEMs use synthetic oil as the factory fill and don't recommend much, if any, engine break-in period (e.g, first ~300 miles).

      https://autoexpert.com.au/posts/the-...in-modern-cars

      Likely, the best explanation for perceived/actual fuel economy is the owner becomes accustomed to operating their vehicle in a more efficient manner. There's also ancillary factors, like adaptive transmission algorithms that "learn" optimal shift points from your driving style. Again, that goes towards your driving style.

      It is not just the engine. Lots of the moving parts have more ‘drag’ until they have a few hundred km on them.
      Brakes bedding in for example.

      If your brakes are sticking/dragging, you should get that fixed. Hydraulic transmissions lack a break-in period too.

      I can only assume you're a boomer because you seem convinced old vehicles equate to modern vehicles.

      Driving like a granny in Eco mode I can marginally eke out 15 mpg.
      Not good.
      Eco Mode makes me wonder. The on off is so quick, sometimes slowing down to make a left it will cut out as you start turn, which isn't great for safety.

      I am indeed a Boomer! I don’t think anything,especially the brakes, are dragging but close fitting mechanical parts are never harmed by giving them a short period to ‘get used to each other’ no matter how good the lubricants are.
      My last car was a 2014 Audi Q5. This new Volvo is the only car I have ever had that has not had a suggestion to be a bit gentle with rpm for the first 1000 km or so. For what it’s worth the 300 miles you mention is 500 km...close enough!

      Yup, I'm referring to folks claiming fuel economy improvements after 1000, 5000, 10k miles. Your vehicle is fully broken-in after 300miles/500km.

      MPG in city drive is hard to compare. Depends on what town or area you are in, there could be multiple stop signs and traffic lights within quarter mile. And in other city area there are longer streets with maybe just one traffic light in half mile and 45mph speed limit. These will result in very different MPG.

      And yet I, for one, saw a steady increase in MPGs all the way to 20K miles with all of my new Volvo's. It is not dramatic, but nevertheless noticeable. Not going to speculate on what part is responsible, but I am sure it is NOT my foot...

      I barely get 21mpg with my 18 Inscription. I got better gas mileage with my 07 XC90 w 135k miles.

      Why did it stop improving at 20k miles? Why not 30k? I mean, it's the internet...

      I'm an Uber driver with a 2012 T6. Lots of idle time, and stop-go. I average between 20.5 and 22MPG, and that's with the last-gen I6 engine and AWD. There's only one way you could get that kind of mileage out of a car with 2 fewer cylinders: YOU!

      Try changing your driving technique. Between stop signs, I gently accelerate away, then get off the gas completely and coast down to 15 MPH, then apply the brakes to stop the car at the line and go again. If I see a red light 1/4 mile away, I just take my foot of the gas and coast to it. Staying on the gas longer is wasting fuel since you'd have to stop anyway.

      My 19 T6 Inscription gets horrible gas mileage. Mind you I only drive short distances in stop and go traffic. Yesterday I went to pick up my son from school and the fuel gauge was just over 1/4 tank and the distance to empty was 100 km and the low fuel indicator went on. This is crazy - at 1/4 tank it only has 100k? The current mileage stats from the volvo app are 19.7mpg or 11.9l/100 km. I only have approx 3500km on the car so hopefully it will increase.

      The odd thing is it is reporting it only has a 71 liter tank - I thought they increased the tank size in the 19's?

      71 liter is about right, 18.5 gal in US. Tank size is increased on T8 only, from 50 liter to 70 liter.

      Stop-and-go traffic is no good for mpg. If one always drive short distance and stop and go traffic, a hybrid car is much better to burn less fuel, get longer transmission lifetime, and not waste energy.

      Thanks. If driven as you describe, and people behind me honking and passing on quiet streets, it can marginally eke out 15 mpg. The dealer says its the Superchargers.

      I've had a couple of '18 XC60 T6 loaners for about a week at a time and I got 21 - 24 MPG combined (60% city, 40% highway) in both loaners driving normally. It ain't the supercharger, it's how you drive it.

      For reference, I'm getting 50 - 52 MPG in my T8 on the same commute (charging once per day).

      Cool. Cool.
      This is 100% city. Short trips. Alot of stop signs. I can guarantee you how I drive it.

      VERY pleased with the fuel efficiency of this car.
      Just did 24.4 MPG on the highway during a 1300 mile trip.

      Per the Volvo app, my average Fuel Consumption over the 9268 miles currently on the car is 21.7 MPG at an average speed of 26 MPH...that's lots of city stop and go!

      What's been going on with your T8 such that you've had to have it serviced twice, each for about a week?
