Hyper Mile Testing Prius Prime. Best MPG possible. Toyota Prius best MPG.

[@bradlysams]

I just bought my Toyota Prime. I absolutely love this car, I was trying to find a video of someone doing a hyper mile test. Some of these videos of people doing "hyper mile" test, are dumb. If you get 25 miles of EV range and only drive 30 miles, of course you get 400 mpg. You did it right. Thank you. Fantastic video and please keep up the good work.

[@grabagearcolorado]

thanks. My thought exactly. Im glad you enjoyed the video.

I have 111K miles on my Prius Prime, and bought my first Prius in October 2000. You did well, but I'd suggest a change for future tests of any PHEV. Don't just run the battery down and then get stuck in Hybrid Mode for the rest of the test, or forced to use Charge Mode to avoid that. Just start with a particular state of charge (50% is good) and maintain that, give or take 20-30%. Toward the end of the test, do whatever you have to, to end the test at the original 50% state of charge. Then you have the true mpg from using gasoline. Separately, figure out how far you can get the car to go on electric. On the highway, it won't be amazingly far. At low speed, it will be far. In my Prius Prime, and presumably all other 2017-2022 Primes, the EV range is pretty precisely the same as 1/2 gallon of gas. If you drive so that you get 50mpg without ever plugging in, plugging in gets you 25 miles without the engine ever coming on. If you drive to get 80mpg on gas, you can get 40 miles on electric under the same driving conditions. Being 32F out hurt your results a fair amount. Being at high altitude helped your results more than the temperature hurt them. Despite the cold temps which would have truly hurt your results at sea level due to very dense air, even in the cold, you were driving through thin air, helping mpg a lot. In moderate weather (say 70F) and just hundreds of feet above sea level, here is the mpg I've learned to expect, with tires at max-load pressure on the sidewall. 80mpg at 40mph; 61mpg at 61mph (and near that speed, 1mpg difference per 1mph.... so 66mpg at 56mph, 56mpg at 66mph, 59mpg at 63mph, etc.); 42mpg at 84mph; 32mpg at 96mph; 26mpg at 104mph. I cringed when you used Charge Mode going downhill. Charge Mode forces the engine to run, to charge up the battery quickly. Going downhill, this is exactly the wrong strategy. Likely in Hybrid Mode, and definitely in EV Mode, the engine going downhill will be off. If it's steep downhill, the battery will be charging up from the descent. Forcing the engine to run then, is crazy. Take advantage of being able to have the engine off while either sipping battery or having it regen from the descent. If you maximize the time the engine is off, you save that much "idling loss" of the friction to keep the engine spinning. So, EV mode (or having the car put its EV light on in Hybrid Mode due to low throttle) is best used during the lightest-load parts of a trip, and the lowest-speed parts of a trip. Using EV Mode uphill during highway cruising depletes the battery in a short amount of time, so the engine is off the minimum possible amount of time instead of the maximum. Many Prime owners think that using Charge Mode at all is a losing deal due to losses on both ends (charging and discharging). They are wrong, but not wrong by a wide margin. You have to really understand the car to beat what the car itself does in Hybrid Mode. Hybrid Mode basically targets getting the state of charge back to where it was when you entered Hybrid Mode, over a period of say tens of minutes, while going above or below it to take advantage of terrain, throttle demands, and so forth to squeeze out efficiency by dipping into it for a few minutes.

Thanks for the comment.

I never thought a Prius would go that far, thanks for showing how powerful a Prius is. Can’t wait for the 2023 Prius to come.

[@YouTubeR-rx9qe]

I agree I can’t wait for the 2023 Prius

[@grabagearcolorado]

Trust me, I was shocked

[@grabagearcolorado]

I plan on getting one the day I can

[@YouTubeR-rx9qe]

That would be great

[@iljapetroff]

Hey, you can achieve more with Prime. Drive behind a big truck as close as possible ( use radar on minimum distance setting) and use recharge mode, once charged to 80% drive as usual, then repeat the cycle. But honestly even if you drive 80 miles per hour in this amazing car, you can still get the 60 MPG which is best of any ICE car on the planet...

[@grabagearcolorado]

I appreciate your comment. We did try that (sorta) with recharge mode to 80%. But we found we averaged 71 mpg. We did this test 7 times (round trips) to find the best result. But it’s possible that with a big truck in front it would do better. I’ll try it on my next vacation.

[@edwardlouie]

Yep I've gotten MPGs like that also in my prius prime with the stock LRR tires inflated to 40 psi. But with Goodyear WeatherReady tires, winter weather (cold weather and lots of rain), running the heat, driving on a highway with 70 MPH zones, and winter fuel with 10% ethanol, the MPG can drop down to 45 MPG. Which is still amazing in my opinion. Out of 50k miles I average 70 MPG with my mix of EV only driving in town and multi-day road trips where I don't charge and do a lot of freeway driving.

[@grabagearcolorado]

It’s an awesome car

[@williamwebberjr8045]

This video is what I needed to make the switch to a Prime.

[@grabagearcolorado]

That’s absolutely awesome. I’m so glad our video helped you. Honestly thank you so much for telling us. Your the first person to say something like that and it made our day. You will love the Prime, in my opinion. It’s a great car. Minor faults in every car but the Prime is great. Seriously thank you for the comment. We 100% appreciate it. -Jared

I agree with you about that hypermiling being only a short trip… I had a RAV4 Hybrid, and was always upset to have a “small battery”… now I drive a RAV4 PlugIn Hybrid (prime) and I start on EV until the first occasion to surpass 50kmh(30mph)… then I switch to HV for the rest of the trip. I drove 800km with a full tank… thanks for showing the trick with charging downhill… I always tried to keep the foot from gas then, but that charging mode would at least add extra mileage for the next start (to the first time I change to HV). Thanks for the video.

[@grabagearcolorado]

I appreciate you comment. Thank you.

[@bmccameron7642]

That's an impressive effort over that distance. I have the previous model, 2012 PHV and typically see around 60 usmpg on a longer, open road trip employing all the same tactics...low speed, high tire pressures, etc. It better when commuting on mostly EV obviously, where I do see much the same figures as you achieved, but never across a whole tank on open road conditions.

[@grabagearcolorado]

Yeah to be honest I wasn’t expecting it. Took way longer than I thought it would. Thanks for watching. -Jared

[@chrisburgess6964]

Ford Escape plug in went fishing. I had limited charging. Found a spot where I could put a few kms on it. Roughly 3.7 liters per 100kms not having the full 60kms of range. When the speed limit was 80kms to 90kms per hr. When it was 100kms was at 4.7 and 120kms p/hr 6.2 liters per 100kms. Not bad but it shows how speed can become a factor. Just using hybrid mode save for later and on ECO.

[@grabagearcolorado]

That’s awesome. These new PHEVs are absolutely amazing and should be the logical next step until batteries are more advanced. In my opinion

[@chrisburgess6964]

@@grabagearcolorado they are for sure. Gas went down to 1.22 now back up to 1.50 a liter I have not spent any money on gas in the city. Other than a trip I don't drive much. I would use the save for later on that trip. Regenerate kms on the sport mode going down a hill. Switch back to auto ev save for later. Touching the break and using neutral on the steep hills.

[@grabagearcolorado]

@@chrisburgess6964 see your doing it right. We got the new Prius prime and did a hyper mile test on it. Check it out. It’s awesome

[@JamesPublisher]

Unreal. You should do a RAV4 prime hyper mile

[@grabagearcolorado]

We plan on it

[@YouTubeR-rx9qe]

You should do a 2023 Prius review

[@grabagearcolorado]

Oh I will. Asap

[@corkiefries9149]

I just got a 2020 prius prime and cant get it to go past 60mpg.Are there any videos that show when to use Eco,Normal,power mode? I charged it and went maybe 10miles on Hv mode and battery was depleted.

[@grabagearcolorado]

We just leave it in eco mode. You should be getting 25 miles per charge. We get 25-30 miles per charge in EV. Then depending on your driving conditions you should get 50+ mpg. Speed is the main thing. Hills go into ev if possible then hv on flat or charging mode.

[@ballouksalim9384]

Question for you : why do you use CHARGE MODE when going downhill if CHARGE MODE gets worse mpgs than hybrid mode?

[@grabagearcolorado]

Hybrid won’t charge the battery. It will slowly drain it. Charge mode will. It gives me more ev range quicker.

[@vevenaneathna]

build a 5lb 12v lifepo4 battery out of 32ah cells for like 45 bucks. saves as much weight as having a close to empty tank of gas. i only get 114-150 mpg in my old solar roof'd chevy volt :/

[@grabagearcolorado]

That’s awesome

[@HazzaALshamsi-sg4jy]

wow its like 1300 km with only 44 liter is this real my friend? i really need this car in Middle East

[@grabagearcolorado]

Absolutely real. These cars are amazing. Thanks for watching

[@al-du6lb]

what year is your prius?

[@grabagearcolorado]

This one was a 2019, we now also have the 2023 which we hyper miled also

Are you also using the heat too?

[@grabagearcolorado]

When the engine would turn on to charge, I would turn heat on. And even then I didn’t use it all the time.

@@grabagearcolorado that is so excellent i hope you'll do the test in the 23 model when the prime is out in the spring
