    rather than ask for a description again of pulse and glide, I searched, I found lots of posts that referred to it but none that actually explained it. Can anyone supply a link to a post they know of. I'm really into this car and want to try to up my mileage, I have figured out that my ride to work includes many hills, so its not the best trip for mileage, I drive on the highway south of me, less hills and average 2 mpg more, but what else can one do. I try to be lighter on the gas, coast as much... any tips would be greatly appreciated.

    Yes I'm listening too. I've read many posts of the technique and the great success of this, but I have more basic question. Where the heck do you drive where you can pulse and glide...and at speeds lower than 42 mph? Even the backroads have speeds fast than that. There are many hills around here and I think that, along with my short errands, just kill my gas mileage. I have over 10,000 miles now...average is 45mpg. I have yet to have a tank where my average is over 50. I'm damn frustrated by it (yes, I check my tire pressure, switched to Mobil 1, try not to speed) but then again, 45 mpg is mighty fine average.

    Pulse & Glide: They usually keep a 20km/h range (60km/h-40km/h or 65km/h to 45km/h in the case of the record tank in Japan). This means briskly accelerating to 60 (38mph) then gliding back to 40km/h (25mph). When accelerating, try to keep below 16L/100km (14.7mpg). That'll usually mean you'll have no arrows to or from the battery and just the engine to the wheels and engine to the motor to the wheels.

    On a flat road, you'll be surprised how long it takes to glide back to 40km/h so be very patient. You'll find places where you had the engine on before but now can glide and lose maybe 10 seconds compared to maintaining the speed with the engine on.

    You can only P&G with light traffic as long as no one's behind you or at least a place where they can overtake if necessary.

    I confess to being a bit of a technology geek at times and even as a retired ole phart am willing to learn new systems, software, equipment, etc. But, as much as I'm enamored with our new Prius I'm gonna just drive it like I drove the Subie we traded on it -- meaning 3-5mph over the speed limit, using cruise, and reasonable accelerations. So far with 2K miles on it we've averaged 48.7 and have gotten 52 on a couple of trips. I just can't drive like I'm in a lab. I'm more interested in the XM screen than the consumption screen -- to each his own.

    Well, To prevent people from throwing molitoff cocktails at me on the roads I cannot do the P/G. So I usually set the cruise control when above 25 mph to the speed limit.

    I anticipate the stops and glide in. I will also feather the petal to use electric right as I come to my destination. I have gotten it so I am at around 3 bars when I come into work. Then when I leave and the car automatically warms up it also recharges the battery to about 7-8 bars.

    I used the MFD to learn the pressure needed to feather. Now I do not need it. When there are small hills I will let the car accelerate past the speed limit but 5-10 mph and then I feather the petal to turn off the regen so I can coast over the hills.

    Also I have found it is better to briskly accelerate to your cruising speed than to do it slowly.

    Doing this I have managed to avg about 60-65 mpg. My daily commute is 17 miles one-way consisting of only 10 mi (freeway at 60 mph, in city). The first 4 mi is at 35 mph and the last 3 mi is at 25 mph. There are some big hills but since I take the same route back it works itself out.
