    Very nice. I drive pretty much identically to that now as far as speeds, lifting completely off the pedal and then lightly pressing just enough to maintain speed, long coasting, light brake pedal with very gradual slowing and stopping etc.. Who knew that I was a Prius driver just without the Prius yet.

    Interesting. I've been pretty much just driving and monitoring my MPG, and these certainly sound like basically what I discovered on my own. You can pretty well summarize as "avoid heavy breaking, accelerate gently, and keep a light foot on the gas as much as possible". I think most people should be able to manage to exceed 55mpg indicated without much trouble as long as they're not impatient, at least in warmer weather.

    Bob,If you're still following this thread, or if anyone else knows the answer to this....
    Is it beneficial to use the air conditioner in a similar manner to how you describe using the heater?
    I try to turn it on and off, at the coldest setting, with the fan on the Recirculate setting, trying to turn it on (if getting too warm) when I'm either at a red light or going downhill, and off when I'm starting to go uphill.
    Also, do you know why taking your foot off the gas pedal and quickly re-depressing the gas pedal functions the way it does to put the HSI indicator lower, as opposed to just slowing down slightly without the brief complete removal of the foot from the gas pedal?

    I find it best to use the AC at as high as temperature feels good to you. AUTO works great for a lot of people, but some people like to tinker with the fan speed. AC is fairly efficient, but obviously the colder you like it the more energy it takes.
    As to your other question...I think if you slowly depress the pedal the system is preparing for the possibility of another need for acceleration and therefore doesn't as quickly turn off the ICE.

    Coming from Cool yesterday I ran into a totally different situation. Normally from the Sierra foothills (CA) to my home outside of Sacto I would get in the 80s using a blended, hybrid mode. Concentrating on using all EV the last 4-6 miles.
    However this time I left Cool( ole gold mining town) with only a 7/8 mile charge. It's all downhill/ uphill, steep, 1000 ft.. This happens at least twice.
    When I finally got to I 80 W my charge was almost zero, so I decided to try PULSE and Glide out of desperation. I took it up to various speeds, 80mph, 70,65 final to 55. Then back up again according to terrain and traffic. I continued this on the City streets at lesser speeds AND a always emphasizing the long glides. I was astounded pulling into my garage with 96mpg. ! Plus some regen appeared, .7 of a mile. I had actually totally run out of charge.

    I've been having better mpg with hard acceleration, about halfway into the power gauge, and much higher than the "sweet spot" mentioned in the video. The way I've heard it is "0.10 gal per second for 20 second vs 0.15 gal per second for 10 seconds" and then backing off into super highway mode by keeping the pedal pushed in enough to keep it at 60-70mpg.

    I'm now getting 51-52 mpg, +2 mpg with hard acceleration, on my 42 epa ct200h

    thank you for your video. I do have a question :
    I live in a city where stop and go traffic is dominant. I hardly go above 40km/hr
    such a low sped traffic, my battery hardly ever goes higher than 3, 4 if i'm getting smooth traffic but still under 50km/hr.

    so my question is.. if I were to lets say pulse until 40km/hr and then release and repress the accelerator until the sweet spot wedge, how can I regenerate battery charge?

    but if I pulse till 40km/hr and totally release and let the car coast/glide the HSI tells me that theres charging when the speed decelerates slowly from 40km/hr to 30km/hr

    what would be the best driving style for my condition. thank you

    Don't let your battery get so low in the first place :).

    If I'm in a situation where I know there will be a lot of stop-and-go that would drain my battery, I'll wait for the car ahead of me to get far enough that I can gas my way to a rolling speed, and then glide with either 0 battery, or just a sliver in the regen section.

    The battery doesn't drain, and since traffic only lets me pulse from 20 - 40 km/hr, the glide after lasts forever and makes up any MPG lost on the pulse.

    If your glide is cut short from the car stopping in front of you, you pulsed too soon, or too fast. Don't be in a rush to brake again.

    No settings. My last tank yield 64.7MPG. After fill up, DTE showed 654 mi. The last 3 months, average tanks were 65-66 mpg.

    I ready do not know how did you do that. My last I fill up 10.1 gallons and DTE showed 459 mi something likes that. On my own calculation. It run 502 on 10gallons.

    Here's what I done to maintain all the change.. what else I need to do to get 55mpg?? Please advise.

    1, 42psi on front tires.. 40psi on back tires
    2, 97 gas from costco gas
    3, Manifold cleaned up
    4, ERG pipe cleaned. (ERG cooler not yet clean)
    5, MAF sensor Cleaned
    6, Throttle body Cleaned
    7, Air filled changed
    8, Oil changed w/5w-20 Pennzoil synthetic
    9, Spark Plus changed to Denso SCH20-11 and Gapped on 1.04
    10, Drive like Gamdma style as this video showed on last 3 weeks.
    Going to change Engine and Inverter Coolant this weekend. And might need to clean all brake disks and pads

    What tires do you have? Make and model. Tires that are not low-rolling-resistance will hurt.

    What is you top normal speed? Common LA and SoCal traffic conditions work against you. If you drive faster than 65 mph, kiss off any hope of 55 mpg.
    Gasoline octane doesn't matter. The specified oil is 0-20, not 5-20. Air filters normally need to be severely clogged to have any impact, though I haven't seen much evidence for Prius specifically. For ordinary non-hybrids with Otto-cycle engines, the filter is virtually irrelevant until it is clogged enough to restrict engine power, but this pattern doesn't necessarily flow through to Atkinson-cycle engines.

    California's special fuel requirements may hurt this quest.

    Bought this used 2013 Prius 93K miles with bridgestone ecopia tires 195/65/15 with wheel cover. And HV battery monitor on 15.9v - 16.9v with Torque App.

    Possibly on my average 19 MPH vs 36MPH on Girt's that different.. but, 52.2mpg vs 64mpg that's huge different. Doesn't Toyota advertising on Prius High MPG on Local drive than Highway drive??
