Around here you have to drive 25 miles and pay $2-$3 more per gallon for E-free. I occasionally do it to winterize my motorcycles, but its not a viable option for a daily driver. I'm in the Midatlantic BTW.
Same here, ethanol free gas is about 30% pricier.

Try some alcohol free fuel. It has more energy
If you’re suggesting that I should use alcohol free gas, you obviously missed the bullet where I said “use pure, ethanol-free gas”...

- Minimize use of the heater fan. This might be the biggest item to save gas. What I found that works well to keep the cabin warm is to turn on the fan to the lowest setting, set the temperature to 70 or 75, and then turn the fan off. Make sure the recirc is NOT turned on so you have air flow into the cabin. You can direct the air how you want (the defrost/floor combo or straight defrost works best for me), but I found, at least at any speed above 40mph, I have enough warm air coming into the cabin to keep things warm.
Even if I don´t have 2019+ RAV4 Hybrid, I had to try this with my RAV4 Hybrid -17
After a month trying, I'm convinced. It saves gas!

That would be nice. I kinda need my winter tires, my rav has a ski box on it, and I value my comfort (and safety) too much to not run the heat in addition to the heated wheel and seats (with AC to defog quite a lot of the time). Fuel consumption has neatly doubled in the winter. Still half of what I burned in my old truck.

Came here looking for help before heading to the dealership. I know that cold weather affects fuel efficiency, but this is just crazy...

Previously, I was a Prius owner for 5 years so knowing "how to drive a Hybrid" and all that isn't an issue. That car would see an drop of about 0.8L/100km in efficiency over winter (winter tires on) in Canada. That equates to a drop of about 4mpg in winter compared to summer.

Now, I have an XSE with 1000km on it and brand new winter tires (Toyo from dealer). The last couple of weeks I've noticed the fuel efficiency plummit to absurd levels where I'm averaging about 11L/100km (21mpg). A colleague at work in the same city is still doing about 36mpg in the same conditions. I can't imagine any combination of hacking how I heat the cabin or ultra gradually accelerate will make up the difference of 15mpg.

Even my previous best (31mpg) from when the weather was much warmer was still far below what you'd expect.

Thoughts???
Have ha my hybrid for 9 months, best mileageon a tank was 5.6l/100 km. Average until November’s around 6. With mixed driving. Now am averaging about 7.4 with snow tires, and much more running to keep cabin temp warm.

How many of you people who are discussing miles per gallon (or liters/100 km) are going by what the car computer tells you, and how many are going by your own calculations based on gas-fill-up quantities vs. odometer readings? There are big differences. Car computers almost always give readings that are too high, often by 10-25 percent.

I've found the onboard estimate to be pretty accurate, actually. Within 1-2 mpg of what I get from using the pump and odometer for any single tank.

Own calculation. I reset my computer each time, and I find it's usually within 1mpg of reality...

My RAV4 Hybride -17 has the most accurate car computer that I ever had. I'm waiting for my new RAV4 Hybrid, delivery in march. And I expect it to be as accurate.

I used to had a Skoda Suberb -12 and a Skoda Octavia -15. Computers in those cars showed mpg +10-12% above calculated...

Since most of my trips are fairly short I leave the heat turned off until I see the ICE is up to normal operating temp before turning it on, so far it seems to help. I haven't done any scientific testing yet but the ICE doesnt come on as soon when I do this and a quick check it seems to help.

I need some cold weather to do further testing, was 70 degrees today though.

When I set to these temps, and then at some point turn the fan off, it seems that the HVAC is then completely off... even when everything is off, is there still heating occurring?

The heat from the engine will still heat the air that comes into the cabin as long as the re-circ is NOT turned on! You will have passive heating in the cabin as long as the car is moving forward.

Speaking of which, another thing I found that helps in this scenario is to lift up your moon roof. That will provide low pressure which will force more warm air through the vent system, past the front seat occupants, and out the moon roof making it feel warmer in the cabin. This also helps to draw the water vapor from your exhaled breath out and prevent the windows from fogging up on the inside.

Did you ever find out what your issue was?

So I'm becoming convinced that Eco mode has a little more to it than just throttle response. I've been leaving my heat in Eco mode regardless of drive mode, but I seem to get better gas mileage in Eco than normal. The main game I've been working on the last few days is trying to get a feel for where the car shifts from EV to ICE when cruising on level or slightly downhill grades. Get the car into EV mode, push the gas pedal down until the ICE starts, release the gas pedal to get back into EV, and push down to just before it switched. Doing this, I've been averaging 38 mpg the last week in ~35-50 degree F days (so 2-10 C).

Ditto on all of this! Efficiency for this car is like a little entertaining game.

Not sure if you noticed, when the battery meter is 75% full or more, the car will stay in EV up to roughly 75% of the first marker in the ECO segment before the ICE kicks in. Versus when the meter has the usual 50% full or less, it will kick out of EV when the needle is even 1mm past the last marker in the CHG segment before going into the ECO segment.

I've now added a small reroute coming home with a downhill grade enough to charge the batteries to near full so I can have little more "give" to keep the car almost fully in EV when I get off the highway to my garage.

My wife drives a 2017 RAV4h Limited. It is rated 34 City / 30 Highway. She knows nothing about how to drive a hybrid correctly. She gets about 34 MPG this time of year, and about 36 in the summer. We usually get about 38 on trips.

We do get better MPGs now (25k miles), then when we first got it. It think it took at least 10k miles before it settled down with good MPGs. So new owners, give it some time.

Its very warm here today, 64F, and I borrowed her car tonight for a 28 mile errand (60% city / 40% highway). Moderately hilly. I got 43.5 MPGs for that trip (trying to drive as best as reasonable).

It will be interesting to see how, if any, better the 2020 RAV4h does, when I get one. On paper, I should get nearly 7 MPG better. I think there are a handful of users here that have had both the 4th and 5th generation RAV4hs, so they will know.
