Featured Stock Toyota Prius Breaks MPG Record for Cross-Country Drive

The guy had to stop a lot. That's what brings the average speed way down.

G5 is a helluva fuel sipper. An overall incredible technological advancement compared to the pedestrian G4.

 

@bwilson4web can tell you everything about the Gen 4 Prius Prime gas-tank capacity, as he deliberately let his car run out of gas on multiple occasions to experiment with it.

I think you can come very close to the Gen 4 advertised capacity of 11.3 gallons before the ICE stops, but the most I dared was within about 1 gallon of that in my Gen 4 Prius Prime.

And my distance to empty (DTE) is still around 714 miles, which is, I believe, for approximately around 10 gallons of gas. So, that is close to 70 mpg average real HEV gas mileage without traction-battery PHEV usage. (Gen 4 overestimates it by about 5 mpg.)

 

Send me an email, obvious gmail account that everyone seems to have. I can send you the paper and two diagrams. I can't send the J398 as I'm cheap.

 

You'll have search the forums as it has been over 5 years since I last owned a 2017 Prius Prime. What I do remember is the Prime requires a 12 V, power on reset if you run both the battery and gas to empty.

Adding a gallon of gas by itself was not enough to avoid a tow. It latched disabling start. Fortunately, I had a Leatherman and got the 12 V ground off and back on. It started right up and I shared a Marine suggestion about Toyota engineering. The previous Prius gave you three starts before latching that required a 12 V power reset.

what gen 6? toyota has flat out said this is the last prius they will ever make, hence the resign and going out with a bang legacy

 

wayne said he went 40-50 mph most of the way in the forum and on the interstate he went 50-60 mph but would avoid it as much as possible. he was literally being '' that prius'' going super slow in the far right lane that gives it a bad stereotype. if i went that slow in in my ioniq, i could destroy his cross country mpg record. i get 135 mpg at 40 mpg and i dont even have a plug in

 

Oh, no, they never said that, and yes, there will be a Gen 6.

 

source?

 

What about your own source?

Nothing was said about Gen 5 being the last generation, and Toyota executives emphasized that they wanted to carry on with it. Why would they discontinue it?

well 2 years ago i heard them say last prius then they will focus on evs only after 2030 and only do hybrids with base cars like camry and corolla and so on, like how hyundai dropped the ioniq and only does hybrids with the sonata and elantra, while using the ioniq name for its EV series. same was supposed to happen with prius. but who knows? this is new info so thanks. sadly gen 6 wont be coming out till around 2030 based on prius body timeline gens anyways. i cant wait another 6 years for a new car

 

Toyota focusing on BEVs?? That won't happen until around 2030. They only have about two BEVs planned for the next few years.

Yes, they will be all HEVs soon.

Gen 6 Prius will debut in the model year 2029. I don't know, but I am guessing it will only come in a PHEV version and perhaps also in a BEV version at that point. If Corolla is offered as a hatchback, then an HEV Prius will not really be needed, but then, you never know.

 

Hello from Japan!
Long time no see ...

Congratulations to Wayne! You are hero of hyper-miler!

Ken !!
okaerinasai !!
yes - long time no hear from you too.
Are you still driving a prius?

I don’t recall this.
Could you share a link, or at least tell us who specifically “they” are?

 

My RAV4 Prime PHEV has fuel consumption ratings for both gasoline (38 mpg) and electricity (36 kWh per 100 miles). A little math shows that for this vehicle, 1 gallon of gasoline is equivalent to 13.7 kWh of electricity. For better precision, I ought to go dig through the EPA's detailed file for un-rounded figures, but haven't yet done so.

The same math applied to the '24 Prius Prime gets 13.9 kWh / gallon. Prime SE, 13.5 kWh / gallon. All within reasonable or likely rounding errors.

I'd like to see how one arrives at this lower-speed 270 MPGe. Someone's actual measure would be far better, though an kWh/mile vs speed graph, just like we see MPG vs speed graphs for various vehicles, would be best.

If it were up to me, "MPGe" would be abolished. For plug-in vehicles, watt-hours per distance is much more meaningful.

 

Hi Hill !

No, I'm not driving Prius anymore ...

However, I'm thinking to try to beat Wayne's mileage number someday by Japanese hypermiler team.

Ken@Japan

 

Wayne's record is strictly for this coast to coast trip.

 

Any country can continuously drive for 3,000 mi. I give the Japanese team even odds!

 

For "shorter" distances than cross-country, the Japanese hypermilers crushed Wayne's latest MPG result long ago. In Gen2 Prii! Though Wayne himself has also demonstrated much higher MPGs for shorter distances.

Remember these results I bundled in an earlier post? All from @ken1784's previous posting life here.

"... But others have done far better in the right conditions. Don't we have a 100+ MPG thread, for whole tanks or extended distances, somewhere here in PC?

The hard core Japanese hypermilers surpassed 100 mpg for whole tanks long ago. As I posted to another thread:
Another World Record 1,460 miles/tank | PriusChat
1,562 miles, New World Record with a single tank | PriusChat
New World Record - 1619 miles per tank | PriusChat
New World Record - 1680 miles per tank | PriusChat
New World Record Challenge: over 50km/L(117mpg) tank | PriusChat
That final one went 1889.4miles, over 3000 kilometers, with a final result of 118.6 mpg."

 

Yeah, we are thinking the same, from LA to NYC!
