    Wayne just called with the 4:30 PM update. He is at mile marker 16 in Pennsylvania. He is 2 PIPs down and lost the PIP right at the 400 mile mark. Currently his MFD is at 72.3 SG 73.5

    The CBS reporter Benno Schmidt is now behind him. They keep leapfrogging their way across Ohio and now Pennsylvania, as Benno left late and just had to stop for gas. At his fill-up he used 9.37 gal. and traveled 390 miles. That give's him 41.4 MPG. I may not have heard the ODO reading right, so there may be a correction coming. It soulnds about right though.

    Wayne said to pass that he has started to come into the mountains. Each rise is getting bigger and bigger. He is having difficulty keeping the numbers up.

    While writing this, Wayne called again and said that Benno just passed him at mile marker 18 in Pennsylvania,

    Whooho! This is so neat. I saw the start this morning while I was drawing blood on the wards, soon as I got home I wanted to check on the progress and wish Wayne good luck!

    I got the question via PM. I will answer it here also as others may be wondering about the terminology.

    On the Prius the fuel gauge consists of 10 bars (I guess they are really squares) refered to as PIPS. The gauge is electronic and the more fuel the more PIPs are visible. The PIPs disappear as fuel diminishes. As a low fuel indication, the last PIP continually flashes to indicate low fuel. I am sure we will here about the flashing PIP before the night is over. It is a non linear gauge. It goes down faster as you get closer to empty. It is a common way to refer to your fuel state by quoting the number of PIPs. Experienced Prius drivers can tell how the start of their tank is going by when the first couple of PIPs disappear.

    Here is a pic of the fuel gauge with 5 PIPs showing.

    LOL - I bet Benno has to stop again for gas just shy of the finish, sometime around midnight or so - unless he pulls a Kramer. If he waits an hour, Wayne, averaging 43mph(?) should be able to pick him up and finish about 2am? Either way, its pretty cool.


    PS - seems like they have a decent tailwind this evening....

    Here is what Wayne is going through for this leg.

    "Pulls a Kramer?" I've done that before. :p

    I have to agree though. Wayne, pick up Benno when he has to gas up the second time.

    This is VERY cool because it may mean that Benno takes about the same time for the trip as Wayne despite driving at higher speeds (I'm guessing he's going faster). So the time "penalty" for hypermiling at 70mpg vs driving 40mpg may be smaller than the general public would expect? The gas stops pull down Benno's average speed, but there may be other factors?

    Jud, is it the next leg where there is a sign marking the highest point in the area or something like that?

    Well, there's a LOT of construction in PA from what I remember, and many of those are 55 zones, which probably cuts down Benno's speed.

    And getting gas can easily cost you 15 minutes. Gas up, take a leak, update your logs, and then go. And that's assuming you don't have to wait in line to get gas.

    The highest point on the trip is about 2200' and is on the next leg.

    Wayne just called and said that he just spent 1/2 hour with the news crew. He had to wait for about 15 minutes and ran the SOC down. The news crew jumped aboard and travelled with him for about 25 miles. He is 490 from the start and at 6 PIPs.

    The MFD reads 71.3 MPG SG 72.4 MPG.

    About 50 miles ahead is the big climb and the highest point on the route.

    Benno is currently 48mi ahead of Wayne with 6 or 7 bars left -- he'll definitely have to fill up again.

    Wayne has 5bars left at 505mi with 295mi to go showing 71.2mpg on the MFD and 72.2mpg on the SG. He should make it. :)

    For whoever speaks with Wayne next, please have the answer to this question ready for him: How much gas is left with 5 bars? Larry? Anyone else?

    His SG indicates he's burned 6.93g (each pip == 1g ??) he's been at 5 bars for the last 5mi or so.

    He's currently 2mi from the highest point on this leg.

    That 7 mile FAS hill I remember very well... about 1/2 mile before it is where I surrendered the HCH-I to Sean after struggling / losing mpg on the way to the first reenactment. Sean got in, and right around a little curve... there it was this beautiful long long hill, winding along and just going and going and going...

    I've driven that stretch on I-80 a few hundred times over that last 10 years - once he crosses exit 160 - it is sweet sailing , there are a few long downhill stretches which he'll simply boost his number on.

    Traffic tends to go a bit too fast, but as long as there IS some construction. He'll be fine, Construction is great because everyone slows down to a steady 45 - 50 MPH

    It is a beautiful evening and he should gain 2%- 3% MPG by the time he crosses the Delaware Bridge (mile 310) .

    The NJ stretch has some serious uphills he'll have his work cut out for him. The stretch Deleware Bridge to GW Bridge is just shy of 75 miles.

    The key to making the NJ stretch successful is not getting stuck in GW bridge traffic - Wayne should be getting there late enough to miss the nightly truckers backup. 45 minutes can happen at the bridge is one catches the late evening rush. It is an steep uphill approach and many a time I've had a record MPG drive only to see it whittle away in a traffic jamb at the bridge.

    Don't use the last Gas Station before the GW bridge on the NJ side - I am convinced they have rigged their meters to run heavy - I once put 19 3/4 gallons in my 18.5 gallon tank at that station.

    I wonder if Wayne has any chance of making a right turn in New York and heading into the Carolinas?

    Just talked to Wayne 7:50 PM. He is at exit 185, 578 miles from the start.
    SG 72.3 MPG MFD 71.4 MPG 3 PIPS remaining.
    He is in the mountains still, but is optomistic he will make it.

    OK I need to know more about the technique he is using to stay around 70mpg. GO WAYNE GO! :D

    Hi Best,

    Based on his history to date, he is 30 miles short of making it on one tank. If he gets 30 plus miles of shallow downhill, so he does not overcharge the battery he will make it on one tank.

    Another way to put it, is he needs an average of around 82 mpg from here out to make it.

    This is based on my 50 miles per pip in this temperature (tank capacity) at 58 mpg in commuting traffic. Which means he has 2.6 gallons left. It was pretty cool last night. So, unless he prewarmed the tank before filling up, that is what he has left.
