2023 Prius LE Problem

Toyota generally introduces a new engine family every 10 years (see the NR, ZR, NZ, and ZZ), though they'll keep using the old family after the new arrives. The 1.8L people wish Toyota brought here for the Prius was the one in the gen3. I was pointing out the 2L wasn't new like the American press implied. The Corolla hybrid overseas got it first. Toyota has moved on from using the Prius as the showcase of their latest efficient technology.

The Eco may have been playing to the tests like the Camry hybrid LE to get the high rating, but the weight reduction and aero tweaks do help on the road. The LE getting nearly the same rating is because of such tweaking.

 

Just looking at the tank average gauge, and then checking it against the fuel remaining, and the miles driven on my tripometer.

 

There is no such thing as a tank-average gauge nor an accurate fuel gauge.

What is your odometer mpg? A picture of it? 65 mpg would be incredible for a nonhypermiler.

 

There's another thread in Gen 5 somewhere with a first time poster of 1 post so far, that says "getting 36 mpg, what am I doing wrong". I can think of about 10 possible things that might be causing that low mpg, but if that poster doesn't have any ideas about how to get better than 36 with a Gen 5, it amost seems like a waste of time listing the possibilities. Also, still getting 40's with the Gen 2 go figger huh....

 

I've seen this on every auto forum I have ever belonged to in the past. One and done trollers trying to stir things up. It seems like there's a contest going on to see who can stir things up the most.

 

Wouldn’t it take less time and be more helpful to list the 10 possible things. Maybe post it as a new thread if it doesn’t already exist. If this Gen 5 is as popular as it’s supposed to be, there are going to be a lot of new comers. Just a thought.

I’ve been here a while and still struggle with the search engine at times. Not complaining…so grateful.

 

@daisy555 so glad you found my post, I was going to post in the other thread, "I'll wait until post # 2, 3 and 4 if they ever happen" to see if there's any more info from the source to work with since none was offered yet.
It's easy for an experienced driver to screw with the modes or just operate the machine as in-efficiently as possible, than complain to get attention. Or I suppose a new driver could make all those mistakes by accident, stranger things have happened.

• speed - how much and when
• traffic - rush hour, heavy, light, none to speak of
• modes - which one or if more than one when for each
• glides - how often
• stops - how many and how fast to what speed after
• terrain - flat, bumpy, foothills, mountain
• ambient temps - what kind of weather, wind direction and speed, etc etc etc.
• tire pressure - when was the last time checked
• mods - stock or list them
• drivers - how many if more than one

​

 

I actually didn’t see your other post stating "I'll wait until post # 2, 3 and 4 if they ever happen". Thanks for explaining.

I’m still needing to educate myself on the different modes. I’m guessing I won’t ever use sport mode. : }

 

*sigh*

The car gets phenomenal gas mileage when driven to maximize its potential. I've stated this numerous times.

Once the weather cools and I can keep the AC off... watch out!

Yesterday I had a 2.5 hr trip where I idled the car a lot in the heat with full AC using the Baby Lambo as a mobile dog house while I did some shopping. Screwed my average up a bit.

I got 650 miles on 10 gallons of gas with my G4 LE. I'll at least match that with the G5. I might even beat it. There was a point a couple days ago where I thought I might hit 700 miles on one tank, but then yesterday happened. And these are mostly full AC days.

What an engineering marvel!!

 

Are you a Toyota stockholder? JK

Amazing results!

 

Why not? The heavy steering feels cool when the roads are windy. Won't affect your MPGs unless you don't adjust for the lighter foot pedal.

I've gotten like mid-70's on an "entertainment" trip, driving for about an hour on my twisty course. Car was in sport mode half the time. Several harsh turns and accelerations occurred.

How can I do this? Simple, I'm in EV mode most of the time. Upwards of 80%. The twisty course is city speeds. After an acceleration boost I'll be winding and winding with no ICE.

The G5's batteries recharge faster, and they decharge slower. It's a big step forward.

 

Naw. This is only my 2nd Toyota. Loved the G4. Love love the G5.

 

I"d be interested to learn how many amps charge mode delivers in a Gen 5 Prime at 35 mph (most efficient speed for charge mode in my Gen 4 so far anyways) takes about half an hour --- to 80% SOC. Amps bounce around a lot with terrain. No rush to learn, just if you want to see someday.

 

Getting good/great mileage in the Prius (or any hybrid) is simply a learning curve. It's also a function of terrain, average speed, outdoor temps, and anticipation.

I got in someone's non-Toyota hybrid SUV who was complaining about not hitting their stated fuel economy (high 30's). I was the driver for an evening, we made several trips/power offs, AC running. I averaged right at 50 MPGs.

 

Also depends on the nature of your drives.

We've been doing nothing but extended drives the last few weeks, about one a week with a hiatus in between. A lot of it middle-of-the-night on near-empty road runs, to the airport. Current tank at 267 kms, with 4.0 liter/100 km, which with the 3rd gen bs factor would likely calculate to 4.3, and that would translate to 54.7 mpg US.

Also, I think our Michelin Primacy MXM4 (in 215/45R17) are FINALLY starting to break-in.

But yeah, by the end of the tank, if we do some short runs, shopping and what not, it'll be back to normal.

 

Yeah, if I could get a flat, empty, 10 mile, 40mph road with no stops were I could do a full pulse (to 45) and glide (down to 35), I have no idea what kind of number I could score. It would be astronomical! I've never driven those conditions. I have hit 120-130 MPGs on an 8 mile course in the city with several stops and turns, with the elevation bias very slightly downhill on my G4 (no AC).

 

Update: Just noticed this question (and my reply) are off-topic for this thread. Sorry.

In your Gen 4:
How are you measuring "amps charge mode delivers at 35 mph"?

The voltage will be different in the Gen 5 vs Gen 4 so comparing amps may not be useful information?

The Gen 4 has an 8.8 kWh battery, with about 6.2 kWh reserved for EV mode, so 80% of that would be roughly 5 kWh charge in your stated 2.33 hours. That works out to charging at 2.13kW or 6A at 350v nominal battery voltage.

Gen 5 has roughly 10.6 kWh reserved for EV mode, so 80% will be about 8.5kWh. The nominal battery voltage in Gen 5 is 266v, but we don't know at what rate it will be charging at 35 mph - "Need Data!"

I just topped off my traction battery last night, but will try to flip into HV Charging Mode and grab a Dr. Prius measurement of voltage/ amperage at 35 mph on my way home. Not a particularly easy task while driving...

 

These numbers don't mean much. People will hypermile or simply exaggerate their mpg. I got 125 mpg on my Gen 4 Prius Prime in 50-mile round-trip HEV stop-and-go freeway driving on two occasions.

I asked you to post a picture of your odometer with the mpg reading. This is closest to the actual average mpg of your car.

 

Given the right conditions, running in HV mode between 55 mph and 35 mph in spots, fairly flat, maybe even loosing some ft above sea level from point A to B, with good coolant heat, just switching to EV whenever slowing down significantly can also produce some unusually high mpg for the trip.

In the other direction, gaining ft above sea level and into the wind, the deck gets stacked against the Primes capability to display almost astronomical mpg.

edit I was kinda surprised a few days ago, after around 40 miles the gauge in the Gen 4 Prime showed 170 mpg.

 

I would say your comment "downgrade in every respect" is hardly based on data except for perhaps the cubic volume part which, in my opinion, makes absolutely no difference in the overall ability to use the interior space effectively.

I'm pretty sure high 9s to 60 plus soft suspension qualifies it as previous Gen lazy pig. Haven't owned one, but road in one often so I do know how it handles and goes. Lazy pig is pretty darn close I'd say whether comparing to 2023 or not.
