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 (2010-12) Fuel :: Pulse And Glide At High Speeds
Correct me if I'm wrong - Pulse & Glide is not really possible at speeds higher than, say 120-130km/h (74-80mph). I have noticed on my last trip that if you want to keep 130km/h average and you pulse up to 140km/h and glide down to 120km/h, when "gliding" the engine never shuts down, and the glide period is very short.
When pulsing back to 140km/h it takes a "long" time and the instant fuel consumption is "high" (e.g. 6-7L/100km) while when "gliding" you are actually at 2-3L/100km, which means on average you are at about 5L/100km, which is what I would get in any case if keeping speed constant with the CC at 130km/h.
Prius C Fuel :: ECO Or Normal Mode While Pulse And Glide
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?

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.

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.

On a recent 3k plus trip where I pulsed and glided a ton, when the PIP was in HV mode but gliding in the sweet spot where I had thought the engine would stop turning, no matter how I tweaked the glide, the ICE always turned at a minimum of 998 RPM per my torque app. The display was always showing 999 mpg in that situation so I assume it wasn't using fuel but just rotating freely. Is that the default behavior for HV mode? I,e, always rotating at 998 minimum rpm perhaps so it can kick in quickly if need be without vibration?? If so, the 10k oil change interval seems dicey as the engine is technically turning all the time when in HV mode. I was planning to change at 5k anyway.

I recently purchased a new prius 2015. When I first got the vehicle and filed up it would say I had approximately 600 miles to go now it says I have approximately 400 something and I actually get a little under 400. So how many miles do you get let tank? Are they mostly highway or town miles? When you fill up how many miles does your car say you have? Also I was wondering how to actually get battery meter to ever say full I can never seem to get the last bar. And when I purchased the car they told me I couldn't go any faster then 15mph in ev mode but I actually can't go any faster then 8 mpg which kind of mashes the feature useless.

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.

I just got a new 2015 Prius C Three and have been reading up as much as possible. I wanted to know if using cruise control would give me better MPG. If it's just a matter of 3/4 mpg difference, then I would use the cruise control to rest my feet. But if its a big difference, then I would avoid cruise control.
My daily commute from Germantown, MD to Alexandria Va and back is about 40 miles each way: total 80 miles. 90% of that highway on I-270 and I-495. I leave after morning rush hour and again drive back after evening rush hour.
Last couple of trips without cruise I have been getting around 50~52mpg.

I am new to the prius 2010.
I filled up last week and I noticed that as soon as a single cell display in the fuel display part has some empty section like 3/4 fuel(single cell) the next day or after that that whole cell disappears without it showing that single cell as being empty.
Around which fuel cell, when displayed, is it important and recommended to fill up gas again, with one cell remaining or two etc.
Prius (2010-12) Fuel :: High Fuel Consumption While Coasting With Charge Available?
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.

So my fuel light started blinking after 480 miles. How much more can I drive it? The display shows 30 miles left before fill up but I read in the manual that when the fuel light starts blinking there is 1.6 gallons left so should that be like 75 miles left. Just wondering. To be on the safe side, I went to fill up.
