Prius (2010-12) Fuel :: Pulse And Glide At Constant Speed?
Two weeks ago we were driving across rolling hills in southern Ohio. I started to wonder, "What would be the perfect road for the Gen 3 Prius?" Is there a road shape that would allow the benefits of pulse and glide without the speeding up and slowing down?
Let's assume no net elevation change on an interstate highway and a driving speed of 60 or 65 mph. To stay in the most fuel efficient engine ranges for the ICE, we'd want down-hill stretches where the power demand shown on the hsi would be in the bottom 1/4 of the total Echo range, and up-hill stretches where we could stay in the top 1/4 of the hsi Echo range (just below Power).
Would the optimal ascent and descent angles be the same, or would the angle of decline be shallower that the assent angle? Would mileage (mpg) be better on this ideal up and down road than mileage on a flat road at constant speed?
Prius Plug-in 2012-15 :: Standard Pulse And Glide At Slow Highway Speeds
I'm talking basically about the equivalent of your standard pulse and glide in the regular Prius. But the PiP would allow you to do it up to 62 mph. However, you would manually have to toggle the HV/EV button to do it. It would be tiresome.

While pulse and glide, is it better in Eco mode or normal mode with Prius c?
Eco mode will take more time to pulse, it may lower mpg?

Prius (Gen 3) Fuel :: Pulse And Glide Method - Shifting Into Neutral?
I am a new 2010 prius owner and I am very interested in obtaining the max MPG in my new car I have read and seen video with regard to the pulse and glide method. My question is
1. can you shift into neutral on the glide
2. can this do any harm to the car.
Prius C Fuel :: 2013 - How To Pulse And Glide - Speed Of Car Without Arrows?
I own a Prius C 2013. I read about Pulse and Glide, and I also watched youtube about it. I somehow have never seen a situation where there is no arrow in the Energy Monitor. The best I have ever seen is arrow coming out of the battery only which is EV mode. Some people say 35-45 is the best speed for P&G, but I never see "no arrow". What speed makes the car run without arrow?
View 19 RepliesPrius C :: Possible To Pulse And Glide On Highway?
I have great success doing pulse and glide in city. I once drove 32 miles non highway at 90mpg in a single trip using this technique. But it seem that it is impossible to do so on the highway, speed goes down too fast during glide. I found that too many pulses on highway actually decrease mpg. How to greatly improve mpg in highway driving?
View 19 RepliesPrius Plug-in 2012-15 :: Using EV Mode To Pulse And Glide Above 42 MPH?
As I understand it pulse and glide should work at pretty much any speed. I'm trying to adopt pulse and glide but I drive on mostly 55 MPH hilly roads. If I'm in HV mode and have some EV range I find I can only get ICE shutoff below 42+/- MPH. However if I switch to EV mode as I back off the pedal the ICE will shut down at speeds up to 62+/-MPH. Switching from EV to HV while gliding at speeds above 43 MPH causes the ICE to resume turning. So I've tried accelerating to my desired pulse speed in HV coordinating releasing the pedal with selecting EV mode to begin the glide then beginning the next pulse by simultaneously pressing the pedal and mode button. Alternatively I can stay in EV mode for the glide then floor the pedal to restart ICE but that risks getting an undesired higher less efficient ICE power level and doesn't allow lower power pulses to allow glides to begin on downgrades.

Brand new 2015 Pruis two.... Still on 1st tank of gas. Can't get it to glide for more than a second or two generally. I'm experienced at the technique from owning a 2006. Could regularly get 50-60 mpg in that car. New 2015 won't let me glide. Today I had a minor breakthrough when it let me glide for 9 whole seconds! Mostly it bounces me between "charging" and "EV" without giving me a true glide. 1st tank is set to deliver a lackluster 39mpg.
I'm not too worried about that yet because I've spend some time sitting the car (with air) learning all the controls that have changed since 2006. Couple of things I'll try next: I have not driven too much in ECO mode yet... mostly just regular mode. Normal commute 24mi round trip mostly highway. I'll check the tires next trip and the parking brake when I run an errand in a minute. Also whether maybe there was a current software upgrade that's suppressing this?
Prius (2010-12) Fuel :: High Temps Dropping Fuel Economy?
While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.

When I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.
Prius (Gen 3) Fuel :: Using Electric Only And Pulse Hard Maximize Commute?
When I first bought the car I was resetting the trip/mpg every day and getting a daily reading. Then I started to realize that wasn't accurate as a per tank reading. So now I judge my weekly trip/mpg. Currently I am getting 57-59 mpg on the MFD(I do not have a scangauge yet) - so i guess that would equal 54-57 actual.
My commute is 43 miles one way. half of it is mixed city driving a mile of low speed out of my neighborhood to a 55 mph with two 2 mile 35 mph zones and then the second half is interstate.
I have been working on keeping the SOC high for the 55 mph so that i can most of the time slip in and out of high speed "stealth" mode. Usually with the MFD around 69-75? and not drop speed too quickly. maybe a mph per 2 miles depending on the grade.
I try the pulse and glide in the 35 mph zones. coast in, then glide as far as I can and pulse back up. I have been playing with a couple ways,
OPTION 1: use in electric only-takes longer and kills SOC.
OPTION 2: Pulse hard into el+ICE and its crap mpg for a small amount of time. Pulse gently into ICE and decent mpg for a little longer amount of time.
Prius (2010-12) :: Squeaking Sound Comes Out In Wavy Roads On Both Low And High Speeds
I bought a 2010 prius 3 weeks ago and a squeaking sound came out after driving it for a week. The sound is like a wooden bed not screwed tight being shaken. My prius has 40000 miles on it and the warranty has expired already. I brought it to a toyota dealership and they could not find where the noise is coming from. I decided to bring it back to the dealership I bought it from and they also could not determine where its coming from. They said they need more time to find it. The squeaks often comes out in wavy roads and bumps and in both low and high speeds.

Traffic permitting, pulse and glide or coast seems to work for the mpgs for those dreaded 1 mile trips on a cold engine. If no one behind, I'll just get off the gas and coast down the street, usually to the next stop light. Funny how often the light is red. If a bunch of ICEers are close behind, coasting not an option.

Just bought a 2012 Prius Three last Friday. The MFD (upper display) shows an average of about 53 mpg so far, and the corresponding 1 & 5 min bars seem to make sense (we have an 07 TCH so we're reasonably familiar).
But the Display Audio unit (6.1 inch) Car>Consumption graph seems to show 100mpg most of the time/most bars. That can't be right and it looks nothing like the MFD display. What am I missing?

I've had an issue with my 08' for a few weeks after returning from a 1 week vacation with the car sitting on the street in NYC. The symptoms are a noise associated with poor performance of the vehicle. It accelerates slower and requires more RPM. When you take your foot off the accelerator it feels as though there is a brake on or some additional drag somewhere in the front end. It's really evident that it doesn't actually glide, but it decelerates rapidly.
