Hello,

I have a relatively new Rav4 PRIME, and in the last 2.5 months, I have added about 2500 miles on the car. Most of those miles are pure electric; however, I was wondering if there was a way to see what percentage of the 2500 miles was driven on electric and what percentage was in hybrid mode?

Thanks,

Go question. I’ve had mine for 2 weeks and wondered the same. I’m mesmerized by the power diagram constantly switching between battery and engine and regeneration and thought about how difficult it would be to determine true mpg etc. i guess a smart charger with good record keeping will tell you exactly how much electricity you use and then you should be able to figure the rest with gas receipts. Not exact but good enough for me. I read that some people reset the trip meter every drive to track their activity.

The simple answer is no. Several threads on this subject, search them.

Thank you for your response. I already go thru the Trip meter reset, and however I was hoping the car has some sort of system to capture this date. Just thought I ask as I could not find anything.

I believe that there is also an option to have the meter reset after each fill-up. Of course if you're driving your RAV4 like an EV with a range extending ICE, then those resets won't occur too often.

The only suggestion I can offer is what I do:

On your next fill, note the gallons purchased

Say 10 gallons.
Multiply 10 X 38 ( average MPG, city/highway ) = 380 - 400 miles on the ICE

2500-400= 2100 miles on EV


That's the best we can do..

As I’m pretty sure has been discussed in earlier posts, no automatic way to calculate miles traveled in HV, but you can get an approximation of mpg from zeroing out the gauge when HV is pushed. Couple of approximations for total HV miles and mpg other than the gauge.

Track total miles traveled in HV manually by zeroing out the odometer and divide by gallons used for mpg and add up all HV miles. I figured out how to do all that and used it to get a good feel for my actual mpg in HV, then quit doing it. My results using both methods were fairly close on mpg but I didn’t keep track of total HV long term miles. The very easiest method would be to estimate typical mpg and multiply by gallons purchased. Some owners like to know how many HV miles they travel in order to decide when to do oil changes, etc. rather than just using the OM recommendations.

Overall for 7,450 miles, my HV mpg varies from low 30’s at 75-80 mph to 40 ish in mixed highway/urban HV driving. My EV Miles/KWh is 3.1, and all of my daily driving usage is in EV. On a trip I always deplete the EV as part of my overall miles traveled plus HV to give me somewhat improved efficiency.

We have a 2022 RAV 4 Prime SE, I have been keeping track of my fishing trips. I begin by resetting both trips A & B. I then drive until the electric range is depleted. For example I traveled from our home on the Northwest Oregon coast down to the Tillamook Oregon area via Highway 101. When the battery was depleted and the gas engine started up I quickly reset Trip B and left Trip A alone. I also quickly reset the gauge to display MPG which then read 00 MPG. I continued on my trip and returned home with total miles of 135.0. I subtracted the total miles from the HV miles from trip A. HV miles was 81. 4 miles which calculated electric miles to be 53.6.

With three fishing trips:
total electric miles: 158.7 ( 3.9 miles / KWH overall avg. last 6 weeks or so)
total gas HV miles: 187.8
Average MPG just on gas HV: 53.8 MPG

Just saying, but if you fill the gas tank to start the trip, then zero out either trip odometer, run in EV until depleted, then note the miles traveled, you would have total electric miles without the A and B thing. Note the total miles traveled at the end of the trip, then fill the gas tank. Subtract electric miles from the total traveled to determine HV miles. Divide HV miles by gallons consumed. That will yield a much more accurate mpg estimate. When I have done that early in my ownership in order to check the gauge estimate vs reality, I have found the HV mode mpg gauge estimate to be high.

I also do fishing trips about twice a month from Tallahassee, Florida to Carrabelle, Florida, a round trip of about 124 miles. My total electric miles (@3.1miles/KWh) are usually around 45, and the HV mpg about 42, with the A/C on. About 100 miles of the trip is @ 55-60 mph on US 98. Perhaps the near constant speed with no braking makes a difference, but I have never come close to the HV mpg you claim. Mine is much closer to the EPA estimate. Sometimes I have played with using the EV miles all during the stop and go portion of my trip to see if it made a difference. It added a couple to the total EV range, but might have knocked a bit off the HV mpg. Not a lot to justify worrying about.

Just filled up our 2022 RAV 4 prime SE at Costco. Regular gas, $4.799 / gal, pumped at the lowest setting just like the last fill up and when it clicks off remove nozzle from tank, just like the last fill up for consistency.

Gas HV miles total for 3 trips: 187.8 miles

Gas pumped: 3.539 gallons = 53.065 MPG

Computer average for all three trips in HV: 53.866 MPG

Dash readout after fill up HV miles: 586

Note: Highway 101 goes through several small towns with speed limits 25-45 MPH, with max. speed limit 55 MPH. There are few places to pass
and vacationers driving 10 MPH or more under the speed limit. On the way back from fishing from when I left to when I pulled into our driveway the computer readout:
Distance: 63.8 miles
Travel time: 1 hr 44 min.
EV driving ratio 61% Note: ( entire trip in HV: battery was depleted)
Fuel Economy: 60.8 MPG

I believe this averages to about 37 MPH.

For comparison we had a 2010 Prius and we took several identical fishing trips to the same area. MPG for the Prius was not much better than the Prime. It appears that Toyota has a very fuel efficient engine for me to obtain that type of MPG for a vehicle that weighs with me in it and all our gear as well, 4,550 lbs (weighed at Oregon DOT truck scale).

The electric miles total for all three trips 158.4. At 11 cent per KWH cost total cost $5.445.

Must be all of the small town stop and go. It takes me 1 hour and 15 minutes to go about 62 miles on a fishing trip. In the 6,500 miles MOL I have on my XSE, my HV mpg has never broken 44, because almost all of my HV miles are 55+ mph highway miles. Destination HV miles are limited compared to highway. Almost no regen braking.

Or, if you have a smart charger it keeps a history and let’s you back into the EV percentage based on electric consumption rather than fuel consumption. I can estimate my EV usage at about 30% (lots of road trips).

My "fishing trip" drive last week from Calgary to Whitehorse 2200 km. Starts on flat roads with speeds of 120 km/h ( 75 mph), then more rolling hills. The last 1500 km are mostly twisty mountain roads at speeds of 85-112 km/h (53-70 mph). Averaged 6.8 - 7.2 L/100 km (about 34 mpg) over the 3 tanks of gas and 23 hours of driving over 2 days. These numbers were calculated from pumped volume and Kms driven, not from the displayed efficiency.

More importantly for me on a long drive was the comfort and ease of driving. Adaptive cruise control is such a great tool. I used a little lane keep assist on the good highways. Excellent acceleration for passing meant easily getting around RVs and slow transports grinding up the mountain passes. The seat was agreeable and I barely adjusted it the whole time.

Really nice experience with a short camping night and hike to break up the drive.

This is a good tip but it depends heavily on the charger and its software and app. Our charger (ChargePoint Flex) is great as a charger and hooks up to our utility's demand management system via wifi and is rock solid, but the app's calculations of energy cost and total mileage is pretty terrible from what I can figure out.

Great charger and hardware, not-very-useful app.

I think it’s because they base the range estimate on the full capacity of the battery (18kwh) and not the ~14kwh that we have access to. I’ve emailed their support maybe they’ll change it. My cost calculations are spot on, but we have fixed costs per KWH with my utility. Im betting that if you’re on some kind of peak / off peak plan the system isn’t aware? kWh should be pretty accurate though, seems like somebody could take the kWh the system logged, multiply it by miles/kWh logged by the car and have a reasonably accurate estimate of EV miles.

I’ll be taking a somewhat similar 1200 mile trip in 10 days, with high speed travel mixed with mountains. Based on previous experience, I expect about 35 mpg overall, and a good comfort level. I do like ACC but find lane assist to be useless since you have to keep two hands firmly on the wheel. If I could rest the hands lightly and let the car do the work might be useful, but that’s not possible.

You didnt get the "Auto-pilot" option??
I drove for almost 60 minutes of Highway Driving with the auto-pilot engaged... Tight turns, she needed a little help...

Here is 1 picture of my Toyota app. It shows in Blue when ICE is off. It gives to me numbers also and prosents of driving all electric mode same as gasoline consumption. My average gas is 1,0 L/100 km for 40 000 km and thats 235.21 mpg US. Average electric consumption is 20,3 kWh/100 km. I have driven 86 % of that 40 000 km ICE off. So have to calculate that 20,3 kWh x 0,86 = 17,458 kWh/100 km.
So my RAV4 driving has cost to me 1,0 L gas + 17,458 kWh electricity /100 km average since 7.9.2020 and after 40 000 km. It debends how much you charge. All electric takes that about 20 kWh/100 km and let charging at all takes 5,8 L/100 km. And those are year around with winter numbers. Earlier model hybrid takes 5,3 L/100 km after 27 000 km when I change to Prime.

EDIT. Sorry but that part was driven in HV mode. Motor starts 4 km before that picture taken. Its about 25 km part of the trip.
