Optimal Conditions for Best MPG (2025 Hybrid AWD)?

[yank283]

Question - as a new 2025 hybrid AWD owner, I'm curious when these vehicles will see optimal gas mileage. The first 3 days I had the vehicle, I was getting 25 to 26mpg in single digit and teens temp. The temps have since gone up to the 20's, 30's and yesterday 43. I'm getting around 37 - 42mpg now regularly (hit 44 for a brief instant).

What is the temp range that is optimal for the engine and it no longer takes a mph hit (factoring in winter gas blend also)? Wondering if I'll ever see those crazy mpg's in 50's like the FWD hybrids.

I can't answer the question as to optimal temperatures but I can confirm that my Hybrid AWD sucked in below freezing temps. 27mpg, and now it seems to be in the low 30s (dash reading 32.7mpg current tank) and we're above freezing during the day now.

So definitely takes a dookie when the temps drop.

The temperature matters a little. Mostly cold temperatures make the gas engine run more frequently. But what really seems to matter is whether or not to need to use Heat or A/C. I've had my Hybrid Maverick for almost two years now and for weather where I don't need to use heat or A/C I can usually easily get well over 50 mpg for mostly around town driving. If I add in a long highway drive then it drops to low 40's for the mpg.

Using the blower motor for the heat A/C causes the engine to run much more frequently. Since I'm not really an air conditioning person I have been able to get 50+mpg from April - October with a sharp decline in the cold winter months. In fact it's a really sharp decline as my average for the months of December & January was 37 mpg..

I definitely had the HVAC off today while using heated wheel and seats only.

Also another reason I got the ceramic windshield film and front windows to try and help keep the cabin cool in the summer.

And also why I opted for a moonroof and that the Lariat has the power rear slider.

From my experience, it really takes a massive dive at 32 degrees or below. Not sure what ideal range is though.

I noticed the same behavior in the Prius V I just traded in. When the temperature goes below freezing, my mpg started to take a hit. To keep mpg in the upper 30s or lower 40s (when it wasn't too cold, like teens & single digits), I'd have to turn off the heater at stop lights and at speeds where it would go into electric only. If I keep the heater going, especially when it drops to teens & below, mpg could easily drop into the lower 30s because the engine would run a lot more. Overall, in summer, I'd average 45 mpg, and in winter if it's below freezing, probably 35-38 depending on how cold it is (and again, this included me trying by turning off the heater at lights & speeds below 45 mph where electric only kicked in).

I've only had my Mav hybrid awd for a week now, but I noticed similar behavior so far. When it was in the upper 30s yesterday, I was getting around 40 mpg in town, and low 30s on the highway, which is right at the epa estimate, so I was pleased especially since the truck is still under 100 miles old.

But in my Prius V experience, optimum as others have said are temps were heater & A/C are not needed and the engine can heat up pretty quick (so goes into electric only mode sooner). The Prius V really liked the 50-70F range and could get around 50 mpg fairly easily. I expect the Mav will be similar.

When it's 40+ degrees it's the most happy. Also winter blend gas has an effect.

Generically, gentle throttle input and allowing it to coast down hills works really well. There is a "science" to learning just how long you can coast towards a red light or stopped/slow traffic before you need to start pressing the brake pedal. The regenerative braking when rolling downhill or when allowing the truck to slow from a higher speed without any physical brake input works really well, and I usually can get pretty close to traffic or a red light before I need to start helping with the stopping. Helps to rack up the electric miles as well as keep the HV battery charged.

Good to know, thanks for the feedback!

Ford Maverick hybrid battery is considered to be within the range of 59-95 degrees Fahrenheit. So if the ambient temp is outside of this range, the ICE will kick in to either cool or heat the battery,, I THINK, not totally sure.

Wouldn’t know what that feels like. Since I bought my Mav it’s been really cold every day. And I live in the south too. I guess I never got a mpg honeymoon phase.

The first 100 miles my 2025 hybrid, awd, 4k was getting 25-29 in town. It's chilly in Mass, at the time of pick up I think it was 10 degrees. Move forward 1 week, temps are in the 30s and I'm seeing 38+, with just over 150+ miles, on the odometer. I do feel temp had a effect.

I haven't seen and confirmed in the logs - no heating of the HVB despite being 15 F out - maybe it needs colder.
What it does do is pull from it for the traction motor while the engine is running, and that eventually warms it up enough for charging to go to it.

But that took 5 min of warmup, and then 5 min driving that started with downhill section where barely any recharge went to battery, very strange seeing 0 amp to battery coasting down hill.

Finally on highway HVB temp up around 20-25 and it started getting charged by fact engine was running. I shared that log in another thread.

I wasn't measuring the HVB temp in summer to comment on that.

But I was surprised that there didn't seem to be any heat going to battery earlier when coolant temp had gone up.
Even my extra phone for the scan data was left out one cold night, in the morning it warned no charging was possible due to being too cold. So I get that part.

What it does do is pull from it for the traction motor while the engine is running. It heats via exhaust gasses. This contraption

Downhill helps. Bigly.
