Look through this forum. There are is a lot of discussion on this. Long story short, there is no heat pump and I would say, on average a 15-20% drop in mpg in colder weather.
^ @Ron_Sea, I agree with virtually everything you've stated - I'm getting pretty much the same average fuel economy as you are with my '22 Tucson HEV. My average fuel economy right now (with mainly city driving) is 7.9 L/100km (29.8 mpg). Btw.. the highway mileage number that automakers advertise is based on the test vehicle travelling at 50 mph (80.5 km/h), but who the heck drives that slow on the highway??! Driving at speeds over 80.5 km/h / 50 mph will cause the fuel economy number to nosedive, as we've both experienced. Short distance drives also help reduce the fuel economy number. The only way to consistently achieve Hyundai's fuel economy numbers for the Tucson HEV is to avoid short trips and drive for good distances (ideally 10 km or more) at speeds between 50 km/h and 80 km/h with as few stops as possible.For me, since the temp dropped, I am getting average 8.2L/100 (28mpg) which is definitely not great. Warmer weather I was getting mid 7's (31mpg), again not great. The only time I get anywhere near advertised mileage is when I am going less than 60km/h. The advertised highway mileage from Hyundai must be when the Tucson is rolling downhill with a strong tail wind because I've never come close to 34mpg on the highway (average speed for me is 115km/h). Realize there are all sorts of factors when it comes to fuel economy but I don't feel like I am driving a hybrid at all. Previous vehicles got better mileage and they were not hybrids (CR-V and GLA250).
I hope once warmer weather returns I will start to see 34mpg with more "break in" but so far I have seen no evidence of this being possible.
100% agreed. Highway mileage should be based on real highway speeds. If I drove 80km/h on the highway, not only would I be a dangerous driver, I'd likely get a fine.^ @Ron_Sea, I agree with virtually everything you've stated - I'm getting pretty much the same average fuel economy as you are with my '22 Tucson HEV.

Note the lack of a heat pump system in the Tucson HEV also hurts our fuel economy.
I've decided my next vehicle will be a BEV (battery EV).

Starboy, I will be very curious to hear how your mileage with your PHEV on the interestate goes. Your in town mileage makes me second guess my decision to not get a PHEV. My HEV gas mileage continues to disappoint, especially on the highway. I think some cars just do a lot worse than others with gas mileage.Yours must be a HEV. I am going from Buffalo NY to Florda with PHEV in 2 weeks I will let you know my readings. In charged state it only idles if heat is needed and as long as I keep my car charged it uses no gas.
So there is 3 display in the dashboardthe trip meter resets every time i drive, but I want to see how i can set this to average out over a full tank of gas.
Just looking for owner's experiences on the HEV in the winter months.
I have read that the phev and hev have heat pumps but they are not too useful when its negative temps out (0 degrees celcius) and I was curious what owners are seeing in terms of mileage numbers translated into fuel savings.
I hope to contribute to the thread soon with real-world data - car hasn't arrived yet!
I have Tuscon Hybrid Ultimate and the performance fell by 30%. In summer months, it gave performance of 15.6KM/Litre which has dropped to 10Km/litre since Dec-2021. I live in Manitoba Canada in temperature hover aroung -20 Dec C on an average from Dec to March monhts.Just looking for owner's experiences on the HEV in the winter months.

^ Same situation here. I'm at 8.0L/100km and it's dropping fast. The advertised fuel economy can only be achieved (maybe) when all the conditions are "just right". Sub-freezing temperatures, multiple short driving trips and speeds above 100 km/h (62 mph) will certainly help erode your fuel economy in this vehicle. Not impressed with what I'm seeing. I think my next vehicle will be an EV, which makes more sense for mostly city driving.When I received my Ultimate last October, I was able to achieve 6.0 l/100km on the cluster. I am currently at 8.6l/100km since it self reset, all city driving. The colder it gets, the worse the mileage as the vehicle needs to maintain heat for the comfort of occupants and to prevent glass from fogging up. When it is -20C, the EV rarely comes on or only comes on briefly as it seems to take a long time to reach full operating temperature. I am sure your mileage will improve once it warms up outside.
The hybrid has a 52 liter tank and there is always a reserve to prevent you from running out of gas which can damage our hybrids.
