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!

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.

I can say for the past week in Edmonton, when it was -26 to -28 my battery stayed between 96 and 98% charged as the gas engine was running to maintain cabin heating.

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.

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.

^ @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.
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).

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.

And I am with you, next car is 100% EV for me. My Tucson HEV is a lease and I am so glad I didn't decide to buy it because I was on the fence about that.

I have the HEV Blue model. I am in the Chicago area. It was 38 degrees Fahrenheit outside when I got off work, today. I drove 96 miles home from work, mostly on the highway at 70 mph. I averaged 35.4 mpg. After I got back to town and filled up the gas tank, it had dropped to 34 degrees. I ran some errands around town and averaged 44.4 mpg. I find that in town, at lower speeds, my Tucson runs in electric mode more frequently. I am pleased with my mileage. I drive normally, and I set the cruise control even while in town. The adaptive cruise control is fantastic!

I have a Tucson Limited HEV and live outside of Philadelphia. The gas mileage has been less than expected. I am waiting to see if it gets better as the weather warms up and I get more miles on my car. So far I have just passed 1000 miles. I am averaging around 30 mpg on mixed driving (state highways, top speed 65, average speed 30 - 40). I have had a few stretches on similar state highway drives when the car was already warmed up that I hit or exeeded the highway mileage estimates but those are few and far between. I had one trip on an interstate with cruise control set at 70 mph on interstate for 50 miles and the car only showed 27.7 (and that was on a day that the outside temp was 40 - 50 deg F). On my combustion engine Audi A4, I am getting above the highway mpg estimate when driving on the interstate at 70. Yup, A4 has lower drag than my Tucson, but wow, 27.7 is pretty far below the EPA estimate of 36. Hoping that warmer weather and the car being broken in make a dramatic change.

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.

 

[Starboy]

Thanks I will be documenting the trip with pictures. Will leave with a full charge and a full tank of gas but will probably not recharge before landing in Florida. I will leave on EV Mode and change to hybrid mode on first gas fill.
