We took the firs trip with the new '25 SX on Saturday, 725 miles total. I drove just under 80 mph the majority of the trip, the car had ~300 miles on it at the start. The first tank was against a nasty headwind, 21.8 mpg. Ugh, it prob didn't help that the car isn't broke in yet either. 2nd tank was 26.4 mpg, still into a partial headwind but not as bad. The last tank was 32.3 mpg, with not much of a noticable wind.

I need to figure out how to get the distance shortened on the smart cruise control, this is the first car we've had with that, and it keeps slowing down as I approach a car in front of us but from way too far back.

 

The distance button is the one that has a car that looks like it's in a lane that just passed a crosswalk with 4 white bars. Hope this helps. On the car's display, it will show the distance between the cars on the top of the display.

 

Same here. Only 110 miles on ours and testing out the LKA I have found it more annoying than usable. It keeps wanting to drift off to the right and then if there is an offramp it wants to take the offramp and on left curves it sometimes wants to drive off the road. Not impressed with the feature at all so far.

Sounds like you’re describing LFA - Lane Follow Assist - which is a convenience feature meant for highway driving…It needs lines to work and tries to keep the Sportage equidistant between them. The steering motor is not strong enough for sharper curves.

Works fantastic on my car w/adaptive CC. One of its best features!

LKA - Lane Keep Assist - is a safety feature that can be turned off permanently. It does not do anything until it tries to “keep” you from crossing a line, which is only useful for drunks and careless TXTers! Almost jerked me into a bicyclist when I crossed a center line to give him more room. More dangerous than “safe”.

Turned off the safety braking feature, too. Warning of a potential collision is one thing, but jamming the brakes on because of (what the computer thinks “could” be) a potential collision, could cause worse problems (like getting rear-ended).

 

Yeah I may have to have them recalibrate the camera as it constantly rides towards the right side of the lane of the freeway and I have to correct it back to the left to keep it on the road. And on some curves on the freeway it will keep going that way until I turn it back to the left to keep it on the road. And at times when it doesn't ride the right line it bounces between the lines like a drunk.
Will see if I can get the dealer to calibrate it but that will be a bit as the dealer we bought it from is fine to buy from but we don't use their service dept so I have to take it to another dealer.

Haven't had any issues with the safety braking. I have had issues with the 17 Sorento overreacting since they did a software update to stop that from happening... (was better before the "fix") It reacts to cars or weeds off the side of the road sometimes now.

 

Most of my driving in IL consists of areas where the speed limit is 40+ with few lights and or stop signs. In the summer I get 40mpg, Winter seems to affect mileage and I get around 32mpg. On the highway at 75-80 I get around 28-30mpg. 2022 Sportage SX-P.

 

PHEV chiming in. Just had my worst gas mileage figure. This was all in HEV mode because the EV range had been used up. Coming home to Cincinnati from Cleveland yesterday. Cold temps at 22 degrees or so and headed into a strong headwind for 1/3 to 1/2 of the trip. Driving at 75 to 78 MPH on the interstate. Started out with basically a full tank of gas and a calculated 300 or so miles of range. It's roughly a 230 mile trip and we were 40 miles from home and I looked down and was surprised to see that my remaining range was only about 55 miles. I ended up at around 23.7 MPG for the trip home. FYI, drove most of my 9 mile commute in in EV/ICE for heat mode and filled up the tank with about 5 miles of gas range left. It took 9.73 gallons. I guess there is a reserve of around 1 gallon of fuel once your gas range gets to zero, but take that with a huge grain of salt.

 

‘25 SX Prestige HEV with 1200 mi. is averaging 33 mpg around town. No long fwy trips yet. Had a good laugh yesterday driving a mile from the gas station to the store, downhill, and watched it climb to 216 mpg!!! lol

 

Ours is still running 39-40 in typical driving. However. When it was cold a while back mileage drops to 38 because it's running the engine to keep you warm and IMO the heater isn't that great on this car. And the auto HVAC overall does not keep it consistent like the 17 sorento does. Now that we are nearing the end of summer and misery season is starting to show it's face with mid 90s temps and 100s around the corner... Mileage drops to around 38 when the AC is running non stop.

So going by that I can see there was no reason to make the AC a heat pump in the hybrid as mileage is the same either way and straight AC is far more reliable than having reversing valves in it.

 

We have 2- 2023 Sportage hybrids and both are SX Prestige. One with 27k miles the other with 51k miles.

In spring, summer, fall
38-41 mpg city/town
33-36 mpg highway

Once temperature drops below 40 degrees
29-33 mpg town
23-28 mpg highway

Huge drop in mileage the colder it gets. The break point is 40 degrees once it gets there it starts dropping and the drop is not linear. At 25 degrees mileage will be in the 20s

 

I haven’t tracked it in detail but this seems to align with our experience also.
Thanks

 

I tracked the MPG on my KIA Sportage Hybrid LX AWD 2024 for (1) year.
Temperature is the most important factor in MPG.
Graphed the MPG + Temperature through the year.

• Recorded avg MPG at each refuel (about once a week)
• Mileage Start: 50 (Aug 2024)
• Mileage End: 12,000 (Aug 2025)
• Location: Michigan, US
• 30% Highway (70+ mph)
• 40% Highway with traffic (40-60 mph)
• 30% City (0-30mph)

Conclusion:

• Advertised MPG of 38 (AWD version) is only attainable in perfect conditions: 70-degree F, <50mph
• Temperature is the most important factor
• Break-in period does not really matter. Not showing up on the graph.
• Tires do not really matter (does not show on the graph, MPG is driven by temp)

 

Getting 38 MPG on highway, even with the posted speed limit, is IMPOSSIBLE, unless the posted speed limit is 55 mph. Anything above - forget.
I see the denser the air, the worse the fuel economy. So yes, colder means worse.
Air drag? Engine inefficiency?

I did not include temp, but similar.
Mine, purchased in March 2025. ODO was 20 miles.
Now, reads 13k miles. Yes, I drive a lot, so almost all of it is highway. I use the NAV CC speed limit, so I let the car read signs and adjust speed (many times it gets confused, but I help it get back on track).
90% highway (or maybe more...) long trips, many times 200+ miles.

Blue is tank MPG
Red is average MPG, cumulative.
Green petrol cost - Costco.

 

I have a 26 Sportage Hybrid SX Prestige, less than i Month old.
Only summertime here I get 38MPG driving around town, and 39MPG on Hwy driving around 70 mph.

 

What do you consider summer.

Like the previous poster the mileage is dependent on temperature. Ours will drop to 36-37 in the summer which means 95-110 and no lower than 80 at night. When temps drop below 95 in the winter mileage is a solid 40 overall. The few days it gets really cold in the teens mileage will drop to 36ish again.

 

It has been in the Mid to upper 90's here in Georgia. 7 miles to town retired. Mostly flat.

 

It's pretty simple science:


Observation 1. Battery loses efficiency starting around 40 degrees.
Observation 2. The more the gas engine works moving the car (vs. EV) the more fuel you burn and the worse gas mileage.

As for highway mileage again simple- it takes so much energy to move a 2 ton brick down the freeway, and more energy to maintain 70 mph than 30 mph.

 

Observation 1 is wrong.
I can heat up battery in my BEV in winter, Bolt, and it still gets lower range. External temperature (density of air) and rolling resistance (colder bearings) influence the range.

Sportage was oversold by KIAs statement for fuel economy.

 

There is an empirical test you can do.
On a nice warm summer day go find a steep hill with a stop light at the bottom. From a stop roll out slow up the hill in EV mode, try and stay in EV mode as long as possible, see where you car engine, say halfway up the hill, kicks into gas engine mode. Repeat again on a cold winter day, you won't make it halfway up the hill this time.
OAT (outside air temp) makes all the difference with the hybrid sportage.

 

Thank you for all of the information.
I'm also looking for a K&N Air Filter they seem to give an increase in MPG.

 

Whew Gosh I like my Hybrid!

 

I have a 2026 Sportage SX prestige hybrid, and after the 600 miles settling in period I took a trip from Raleigh to the Outer Banks and went up and down the barrier Islands. Two thirds highway driving, but NOT interstate, the rest regular roads, one lane in each direction or two lane with lots of stop lights. Total of about 600 miles, starting with a full tank of regular gas and refilling at the half way point. First tank gave me an average of 37.3 mpg, second tank 35.7 mpg.

 

I have a ‘25 Sportage PHEV, which is a little heavier given the battery requirements. I get an over mpg of mid to high 30s when driving solely in hybrid mode. Considerably better in stop and go traffic when I can drive 35-40 mph and coast when practical. Needless to say, when employing electric mode and not doing trips exceeding 30+ miles, no gas is used.

 

30ish seems to be the average in my 2025 EX.

 

My 2023 SX-P now gets about 35MPG average in good weather when I’m driving a decent average miles as on short trips under like 10 miles it just kills my mpg. In the winter it’s more like 27mpg so it’s a significant difference.

As mentioned earlier in this thread I did struggle with mileage earlier but now I’m around 11,000 mileage and I get 35mpg consistently as long as I’m not doing a lot of short trips. Short trips mostly engage the ice and the mileage on that is dreadful.

 

I mostly drive short distances around town. The last fill up it (The computer) registered 32 MPG.
Coming from a 2022 Toyota Tundra only 18 to 19 MPG I don't mind the 32 MPG for now.

 

Here is a picture from yesterday when I went to Dahlonega about 1.5 hours 1 way.
This is when I was close to getting home. I set cruise control and let it roll.

 

Just for the fun and giggles... I just did a round trip, 95% highway, sunny day. 75 miles one way, so total 150 miles.
Morning was warm, about 16 C. Traffic small, open road, no stops. A couple of little slowdowns. No AC.
Afternoon, return, warm, 26 C. A bit more traffic, a few minutes (about a mile) stop and go. AC set at 23 C.

I set the CC speed at 60 mph. All the time except on the side roads (35-55 - total maybe 4 miles on those roads).
According to the Google Maps - elevation change - drop 400 ft one way, gain 400 ft on the back (makes sense right?).

The only difference on the way there I was on reserve fuel, on the way back full tank. No, I did not drive 75 miles to get gas

Results?
Impressing.
Way there 47 MPG US indicated.
Return 44 MPG US indicated.

I find my car to be very close to calculated vs indicated.

When I was covering this route at 70 mph - I got about 38-36 mpg. Just a few days earlier. Same weather, same traffic.

 

It's ben my experience that it does better cruising.

Misery season where it's 95-115 it drops to around 34
Summer part 1 and 2 which are either side of misery season where it's 92-95 it's 37ish
Spring and fall it's 40 or so
Winter spells when it was 12* drop it to around 34

Lots of stop and go driving will drop you to 34 and possibly less. The PHEV is a better choice for those with mainly in town driving and very high and very low temps but performance of the battery drops off in both temp ranges so take that into consideration.

I haven't done a long distance trip with ours yet to see how it does on them but the high temps will degrade that allot here. I prefer to fly as I hate road trips.

I wish the display of the hybrid section was better. It's very simple on the 25 and there is no data logging as it resets every time you open the screen. It would be interesting to know how many KWH you have regenerated over the life of the car etc.

Oh and as for the calculated on the dash vs doing the math when refilling i stopped doing the math because it's really close. The fuel flow sensors and injector calculations are pretty good now. And for those saying car companies lie about mileage numbers. Well no they don't They have to publish numbers done on an EPA test cycle and they have no influence on those numbers. Driving style temp traffic terrain play a huge role in mileage.
