I got my 2021 Prime in Oct of 2021 and have been averaging 63 mpg. It all depends on how far you go. If all I did was city driving or driving less than 45 miles I would never need gas. We take longer trips so the milage drops due to using the gas engine more. It is still very economical and the Prime is fun to drive.(fairly fast)

 

My wife and I purchased a 2022 RAV 4 Prime SE 3 weeks ago. So far we put nearly 1100 miles on it. Electric range is pretty consistent 42-47 miles, this is driving on highway and in town areas were speeds vary from 55 MPH highway to as little as 20 MPH in town driving. We live in N/W Oregon on the coast and average temps range from 40's to high 50's this time of year with rain at times. My wife drives her 32-36 mile roundtrip commute with 2-8 miles of electric range left sometimes a little more on a warmer day.

A couple of days ago I was driving and my wife and I went fishing in our Prime. We only had a partial charge and went 28 electric miles then when the engine switched over from the depleted battery I reset the gauge to MPG. When we pulled into our driveway after the trip, 53 total miles, MPG indicated 50.5 MPG, thats just on gas hybrid mode. Thats impressive as we at one time owned a 2010 Prius which was not all that much better on MPG than our Prime. Weather was dry with temps in the upper 50's and roads were rural 45 MPH speeds, some city and highway 55 MPH speeds. With nearly 1100 miles driven on our Prime, (which includes 2 trips to Portland Or. total of 380 miles) we only put in a little less than 9 gallons of gas from the original full tank the dealer supplied. Simply amazing for a 4,500 lb. all wheel drive SUV. In closing regular 87 octane at our local Costco is $4.499 per gallon but our electric rates are only 11 cents per KWH this is delivered with all costs, taxes, etc. included. I understand the RAV 4 Prime is nearly impossible to get especially at MSRP, now I can see why.

 

Click on my Fuelly link below and join. You can go there and look at all members with Primes and even by trim to get the info you are looking for. My last tank was 76 mpg, we drive 10 miles highway each way with errands “in town” in between, and road trips. The number in my Fuelly banner is ALL data since we drove it off the lot with 6 miles on it.

 

I use fuelly for my gas ups, but how do you track charge ups in fuelly?

 

The very first time refueling -- at 1937 miles!

 

I am back up to 40-42 miles of range from 30 miles of range during the Winter months.

I drive 80 mph in EV and get 2.7 miles per kWh when temps are in 60 degree range which I believe is the optimum temp to maximize battery efficiency.

 

I have only averaged over 4500 miles 2.4 kWh

 

I drove my R4P for 505 miles (TripA) and refilled to 10.6 gallons. That gave me 48 mpg. NO miles from the EV contribution. If EV miles were added to TripA, i'm sure the mpg figure would have gone up accordingly. YOU CANNOT SIMPLY CALCULATE MPG BASED MOSTLY/SOLELY ON MILES FROM THE EV. That would skew the mpg figure and mislead people.

 

I’m averaging 3.2 miles per kWh with a ton of 65-70mph driving. Curious for others miles per kWh?

 

2.5

But, up until recently, the bulk of EV driving is going up a hill, from our house, which climbs about 3400 vertical feet in 6 miles. The up uses 30 miles of range. The down puts about 10 miles back in the battery. So not terribly efficient.

 

Yesterday I took our 2022 RAV 4 Prime fishing down to Tillamook Oregon from our home along the N/W Oregon Coast for a little Steelhead fishing. The trip was 130 miles round trip I left our home with a full charge and traveling south on HIghway 101. I made it 48 miles just on electric. When the battery switched over to the gas engine I reset the gauge on the dash to reflect the change to MPG. The roads were dry and temps were in the low to upper 50's at the highest, I had no heat on as I was quite comfortable. Speed consisted of 25 MPH in town driving and highway speed of 55 MPH as Highway 101 goes through several small towns.

When I arrived home a took a photo of the dash which read 49.5 MPG just on gas. Impressive to say the least for a 4,500 lb SUV all wheel drive.

 

We don't get anywhere near the actual mileage of most of the posts on this thread. If you believe the computer maybe we would get close but actual mileage driven divided by gas or electrical charge level isn't even quite up to the EPA estimates. Maybe it is the hills or my wife has developed a lead foot but we don't quite get 42 miles on a full charge or 38 MPG in HV on the highway. And I drive conservatively. Don't get me wrong I love our R4P and we are only on our 3rd tank of gas since August on 2021. But some of these numbers are hard for me to believe.

 

We are splitting hairs here.

We get about 38 highway mpg, roughly 75 mph ish.

The fact is that when we fill the tank, the “clock” starts ticking, when we fill it next time it stops. The economics of it work out to 76 mpg. (Our last tank). For the record, I do track the electricity used through my ChargePoint app and add it to my program for tracking maintenance costs etc so it is factored into cost of ownership. Is it 100% scientifically, empirically provable in court, of course not.

In the “real world” it IS true, if we do the exact same process (other than the plugging in part) with our other (pure ICE) vehicle the mpg is absolutely not 76.

So, the “real world reality” (for people who aren’t super anal engineer types) IS that now they have a better car and are spending less money every week.

Sorry, no. Perhaps the “economics” works out to be 76 (in your case) with the added electricity, but the electricity isn’t free. That’s the real world, because we (if we plug in) are combining two forms of power, both of which we pay for. Even solar home charging has a significant hardware cost. We are spending less overall on driving the Prime, but the efficiency metric is not mpg, and posts proclaiming absurdly high figures as if they were comparable to an all ICE vehicle are really misleading. I’m glad to be getting 35-45 mpg HV and about 3.1 miles/KWh EV though.

 

As a general personal opinion, people are free to use their vehicles legally as they see fit, in any way it pleases them. Even so, I’m perplexed with posters that proclaim they have used just a few gallons of gas and gone many thousands of miles in their Prime. Heck, if I traveled that little outside of town I would have a BEV, not a PHEV. Why carry around that ICE and pay upfront for it when you don’t need it? I bought a PHEV because I do take frequent trips where a BEV would need charging, and the current charging situation isn’t good enough in my area (as well as battery tech) for my driving pleasure or security.
I don’t get it, but don’t resent folks that make a different calculus. Still head scratching, though.

 

Did you skip over the part where I said I keep track of the cost of electricity too?

 

All of my numbers (and my Fuelly banner) are “by the math”. The only thing I use the guess o meter (In The car) for is the average mpg since we bought the car, which is over 48 mpg.

 

Those numbers are misleading because they consider the electrical energy free...so the mpg numbers are super inflated.
You are right that the Prime has relatively low operating cost, but that's not looking at "efficiency."

 

We usually fill up on gas around 1/4 full, as is recommended for all ICEVs. We have gone over 2000 miles on a single tank of gas when we have not done out-of-town road trips, and I calculated that for some tanks of gas, we are getting around 185 mpg.

 

I got my Prime 9th of september 2020. Now driven 45 000 km. From February to june 2021 I drove 7002 km and fill up after that 38,02 L gas. Thats 0,543 L/100 km, which is 433.19 MPG. I havent never zeroing average kWh meter and its now showing 20,1 kWh/100 km.
After 2 years gas consumption shows 0,9 L/100 km, which is 261.35 U.S. mpg. Here are Toyota app pictures with GPS kilometers.

Those 2 last ones are my lastly month drivings with 0,3 L/100km. So that is 784,05 MPG So far.
My average year elerticity consumption is that 20,1 kWh/100 km and Ive been driven 88 % in EV only mode. So thats for year total energy
(0,9 L gas + 17,7 kWh)/ 100 km
Not bad from my Prime.

My Solar panels will produce about 7000 kWh this year and my Prime will take about 4000 kWh. So must were to put that overdose.
