How fuel efficient has your '17/'18 Impreza been so far?

Year, model, transmission, city/hwy, driving style:

'17 Impreza Sport-Tech hatch, CVT, mixed city/hwy, mixed driving style depending on traffic.

The car has been averaging anywhere between 10L/100km to 14L/100km since new. I've tried granny driving, easing into stops, and tires are always inflated to spec, etc. I never see 6-8L/100km. At some points, it even reaches into the 20L/100km range for sustainable amounts of time. Took it to the dealer while it was in for a regular maintenance, and they took a look. They said it was driver & weather related, nothing wrong with the car.

I wonder if this recall affects it at all:

We bought this car partly because of the advertised excellent fuel efficiency, especially with the added incentive of an even more thrifty CVT vs the manual, but we are consistently getting less than 450km/tank. Were we wrong in expecting 500-600km / fill up? It's left us puzzled & unImprezed on such a small car that is also a Partial Zero Emission Vehicle. Where's all the fuel going?

According to driving.ca, the CVT hatch should be around 8.5L/city & 6.4L/hwy:

First Drive: 2017 Subaru Impreza | Driving

As far as CVTs go, this is one of the better ones, and does a fairly good job of emulating a traditional stepped automatic when the paddle shifters are employed. The benefit, of course, is improved fuel economy. The hatchback with CVT is rated 8.5 L/100 km in the city, 6.4 L on the highway; with the manual, it’s rated at 9.5 L and 7.0 L. We averaged around 8.4 L/100 km.

I was wondering if the cold weather was affecting it, but it shouldn't factor in that significantly. In any case, the less than ideal fuel consumption has been the same since we purchased the car, and drove it through spring, summer, fall, and now winter.

I just wanted to compare to other Imprezas to see if it's normal/expected, or if I should have Subaru take a look at the car again.

Disappointed so far. Having to refuel so often, that the gas bar attendants are going to know us on a first name basis sooner than later. Hopefully it gets better.

17 Sport Hatch, CVT, 50/50 highway and city
Mine averages 33 according to the screen, but I measured it and it is closer to 30. I do have my tires inflated pretty high though at 45 psi, but I have a heavy foot:grin2: Overal my model gets fairly good gas milage, and if I drove more conservativly, I feel like I coud reach the advertised numbers (like when I am driving 40mph I can hold 50mpg without loosing speed). Try making your information screen show the current gas milege, it helps me recuce gas consumption.

I'm an oldschool guy, love my -1980's cars. I hate looking at the all fancy gauges while trying everything to save fuel now, bc it takes away from enjoying the drive. And since that doesn't seem to improve anything, I find myself driving it the way I like now, bc the car is actually quite fun to toss around.

My fuel efficiency is definitely worse in the winter with my snow tires on, but I still get better than 10L/100KM.

I monitor my fuel economy like a hawk and I'm around 9.2 to 8.5 this winter season. During the summer, I was around 8.3 to 7.7.

I'd bring it into the dealer to get it checked out if you're getting 14. That's nuts.

I bought my 17 sport with cvt in November. I am averaging around 9.8l per 100km. Mine is about 50/50 driving. Last trip I went on, I drove at the speed limit and still only averaged 8.5. I will be bringing this up to the dealer when I go back. I'll wait to have my regular tires back on it.

Also a side note, what is displayed is a false number. When I checked it last it was off by about .5 l/100km

It's at best an estimate, but then again so is relying on everything to be consistent from pump to pump. Ideally you'd only ever fill up at the same pump for your calculations. Figure out how close it is to doing the math yourself, and then you can probably stop bothering doing the math.

Mine uses 9.3L/100km, mainly on 80km/h road and some stops. If i use 95RON, it will drop to around 7.8L/100km. i think the best way is to try a higher octane petrol.

So far over the 800km that we've owned the car the average is 7.8. The first 650kms were over 6 mountain passes the last 150km have been local driving of up and down a 11km long hill with 600m elevation drop/gain.

Blown away by how good it is.. Will update as we drive it more.

About 2l/100km less than my 2003 impreza

This is my best Gas Mileage to date on our new Impreza - mostly set from a roadtrip from Ottawa to Toronto. Automatic, hatchback, touring, 90/10 Highway/City, drive like a grandpa. Engine is now broken in and summer gas is here.
Wow, that is amazing. I only get under 6l\100km once when I drive my 3 months old daughter from Ottawa to Toronto in my scion iM cvt.

Things haven't improved. 2017 Sport-Tech still averaging something between 10-+11L/100km which roughly translates to 21.39Gal. I'm barely getting 400km to a tank before the low fuel light turns on.

My friend's brother in-law has a 2018 Crosstrek, essentially the same car with the same engine, and he's averaging -7L/100km (33.60Gal), mixed city & hwy, and even got it to -4L/100km (58.80Gal), which yielded over 800km. Is this realistic? Is this an anomaly? Are any of you guys getting similar numbers?

Sleepy, I have a 2019 Sport 4Dr. with manual transmission and I'm averaging just over 10L per 100km also with about 50/50 city/hwy. Car is just a few months old and just passed 2000 kms. I'm just hoping that after the first oil change it will yield better mileage as it should be pretty well broken in by now but after reading your post I'm all depressed now!!

I'm being in your shoes as well driving 17 Impreza Premium hatch with CVT and averaging around 10l/100km from last March through summer, but now getting worse to 370 km from tank for 42l of premium gas taken. Car drives great for a 2l 150 HP engine, has 45 K km and and doesn't show any faults. Was bought used with 32 K km on a clock.
After reading all those posts about Imprezas getting 35 - 40 mpg I started thinking former owner chipped our car to make it faster and this is a problem.
11.2 liters per 100 km I got from last tank = 21.3 mpg

It is January 2020 now, and it is still the same. The car is still averaging +10L/100km and less than 430km on a tank with the low fuel light on. Dealer won't do anything and still claims that nothing is wrong, but how can other Imprezas yield so much more? My friends with a 2018 Crosstrek, 2017 Forester XT & a 2019 Forester (albeit different cars but I assume being bigger & heavier vehicles) are experiencing much better fuel economy. Disappointing, to say the least. I was looking forward to long term ownership, but I am looking at changing things up now.
