i am a commuter - i drive approximately 150 miles per day or more- 95% of those are highway miles - since getting the car this month i am only averaging 25 mpg, in eco mode, while coasting on the highway @ 75 mph also using premium gas. Am I crazy to assume under those conditions i should be at least averaging 27mpg? When I purchased the car i really thought that i'd average closer to 30mpg perhaps 27 or 28 worst case scenario. Also if im not going to average epa estimates with premium would I be fine switching to 87 octane?


aside from the MPG i LOVE the car!!!

You should see an improvement after getting some more miles on it. I have also found that where I live the fuel blend changes for the winter and my mileage drops 2-3 mpg. I live in California, other areas of the country also supply different fuel blends in the winter. I drove to Yosemite National Park this weekend about 370 miles round trip. I averaged 25.8 mpg. I have made this same trip in the summer months on the same roads and averaged over 28 mpg.

Dan made a great point about the winter fuel. It makes a difference. Also--what PSI are you running in the tires?

I have a T5 R Line with the 20" wheels. 31k mile on it. Averages 23.5 MPG on a good day. 80% highway at 70 to 80 mph. I didn't buy it for fuel economy anyways. My other car only gets 16 mpg average.

My XC 40 now has 10,000 miles and has never gotten more than 22.5 MPG either highway or City and
the dealer has been unable to explain this or help.

Same '21 T5 with 2,000 miles. A very disappointing 25.4 mpg is my best. Surely isn't 30 mpg, and I am a coaster! Would not have bought it if I was going to get anything below 30 mpg! All my past cars, I got over the stated mpg. I was expecting 33 mpg's.
I love this crazy little car, but I hate hate hate this mileage.

The MPG thing is funny. I have long given up on believing anyone's posted mileage are reasonable. Still our 1997 Land Rover Discovery I got in 2000. In the beginning, I was getting about 16~18MPG. Later in life and set up for off road, I get 11~13mpg. The car the XC40 replaced was a 2003 Infinity G35 Coupe that got about 18~20MPG. My company car is a 2019 Ford Escape. If I get 22MPG out of this "economy vehicle", I'm happy. Best value I think I ever had was my old company Toyota Sienna mini-van. 20MPG with a big v6 powering a large vehicle. I annual get a chance to drive a fair number of rentals due to travel so I get to see how other cars are economically. I guess it's all a matter of perspective. Time will tell how the XC40 stacks up. So far I find it no better and no worse than others I have tried. I like the car so I don't worry about it too much.

Comment from the UK - my XC40 T5 gives 28.2mpg (average across 8,000 miles, normally in "comfort" mode) - BUT this is UK gallons which are 20% bigger than US gallons. My 28.8mpg (UK) is equivalent to 24mpg (US), which seems similar to USA experiences. Canada uses UK gallons, I believe.

Same boat. I spend most of the time on the freeway and get 21.9 the majority of the time. ive seen 26 while on a 1500 mile road trip and thats it.

We've used liters in Canada since the mid-1970s. I still prefer to calculate my mileage in Imperial miles per gallon. I found a neat trick to change the car's settings to Imperial and the trip computer displays miles per gallon. My current reading is 27.2 mpg and that's in Normal mode. I look forward to driving on a major highway in ECO mode. MyT5 R-Design has Polestar Optimization and I wonder how this will affect my mileage when I let 'er loose?

Just coming to say I'm in the same boat as ya'll! Coming from a Subaru Crosstrek that seemed to last forever on one tank.. this is miserable lol

There are other threads on this too. Three points from someone at 43k: (1) I saw a big improvement at 20,000 miles.. not sure why it took that long. (2) The Economy drive mode does actually make a noticeable difference. I can only stand using it on the highway, though. (3) Economy is very dependent on the conditions in the XC40. Any wind, uphill grade or elevation increase, low temps, aggressive acceleration, or driving past 70 will drastically decrease your economy. I am getting 30 mpg driving an even 70 on the highway in good conditions. Average over 43k miles and 3 years in the Midwest is 26 mpg and that’s mostly highway with attention paid to efficient driving.

THIS website states that you get 23% lower fuel economy at 75 MPH vs 55 MPH.

So, if you think the car should get 30 MPG at 55 MPH (EPA estimate), you'll get 23 MPG at 75 MPH.

That seems to match your experience.

Maybe the car is just fine.

I have the 2020 XC40 Inscription with the T5 engine.

I was definitely spoiled. My previous vehicle was a 2014 VW Sportwagen with with a standard 6 sp transmission and the infamous 2.0 turbo diesel. I had a Malone 2.0 tune. I was averaging 42 MPG on highway driving, usually at 70 - 75 MPH. Then after the big stink and "fix" it dropped down to about 38 MPG. I sold my VW with about 135,000 miles, and still running great.

I purchased the XC40 for comfortable long trips for my wife and I, not for economy, so I haven't checked my mileage, but with almost 30,000 miles on the car it has been quiet, trouble free and very comfortable. I couldn't ask for anything more.

2021 Momentum/T5 with around 1,000 miles on the odometer.

We got 22 MPG towing a camper through the low hills of northern Vermont last week.

The car still idles at like 1,500 RPM so I hope it will get better after some kind of break-in period and the engine controller lets the engine /transmission shift into a higher gear.
