    Presenting the Summer 2009 Challenge, running from June 1, 2009 until September 31, 2009.

    [FIMG=right]http://www.cleanmpg.com/photos/data/501/07_TCH.jpg[/FIMG]Andrew McGuckin - CleanMPG - June 1, 2009

    Summer is here. Depending on where you live, rejoice or weep. Join us in our quarterly challenge to beat the EPA mileage ratings. The winner is the driver who beats the EPA by the highest percentage.

    Drive your daily routes in your normal car. Real-world cars, real-world routes, everyday conditions, etc. This is where the real results prove the value of hypermiling. Remember the CleanMPG motto, "Learn to raise fuel economy and lower emissions in whatever you drive".

    Please note that this is a 4-month challenge, instead of the normal 3-month runs. This is to align it with standard quarters used in business, and in our own Alternative Transportation Challenge.

    Results from previous economy runs:
    I: February - May 2008. Winner: PaleMelanesian
    II: June - August, 2008. Winners: CobraPond (A), lamebums (B)
    III: Sept - Nov 2008. Winners: CobraPond (A), MT bucket (B), jps000 (C)
    IV: Dec 2008 - Feb 2009. Winners: lnmcmahan (A), GaryG (B), jhu (C)
    V: March - May 2009. Winners: lnmcmahan (A), nissynis (B), Damionk (C)

    How to Join
    To participate in the June to August economy run, all you have to do is the following:
    1. Create a new mileage log. This will be an alter-ego of your vehicle, except make sure you use the 2008 EPA ratings for your car found at www.fueleconomy.gov. CleanMPG staff will move your vehicle into a separate category for this challenge. Please use a new log and leave the winter logs as-is until the previous Challenge results are finalized.
    2. Post here in this thread to announce your participation. Be sure to include a link to your new mileage log.
    3. Post in this thread with updates. Start wherever you are now, and use your next fillup, whenever it comes, as the start of your log. There is now no minimum mileage or number of fillups, only a request for no single-tank entries. We want complete daily driving records, and not cherry-picked entries.
    The standings here on page 1 will be updated periodically.


    Handicaps
    For a level playing field, we will all use the new revised EPA estimates for fuel economy. If you are using a handicap, please list it when you announce your participation.

    Hybrid Handicap: Reduce your epa ratings by multiplying by 0.85. Hybrids are already optimized for good mileage by automatically doing many of the things hypermilers do.

    E10 Handicap: Reduce your epa ratings by 3%, to match the reduced BTU of 10% ethanol.
    Part-time E10: If you only sometimes use E10, log 3% less fuel used when you record that fillup. Make a note in the comments for the tank. Example: "Pumped 10.3 gallons E10, logged 10.0 gallons". Use this adjustment for the fill that finishes the tank of E10 fuel, not when you put it in.

    E85 Handicap: If you are using E85 instead of regular gasoline and EPA ratings are not available, you can estimate your E85 rating. Just lower the gasoline numbers by 25% (multiply by 0.75) and round to the nearest MPG. Enter this as your EPA rating.


    Which Division?
    This was created to help divide people into three levels, in order to increase competitiveness.

    For Returning Members:
    If you were in the top 2 or 3 in your division, please consider moving up.
    If you were near the bottom, consider moving down. Everything is more fun when the competition is close.

    For New Members:
    If are are new to hypermiling or to this challenge then I recommend either the B or C divisions to allow a good chance to get on your feet and familiarize yourself with hypermiling.

    Previous run, now finished: http://www.cleanmpg.com/forums/showthread.php?t=19925

    Some notable changes this time:
    - modified hybrid handicap - this will make the hybrids even more competitive
    - E10 handicap
    - no mileage minimum, just be active through the whole challenge
    - 4 months instead of 3, but just this time, to realign with standard quarters.

    I believe gasoline in California contains 5.6% ethanol, unless this has changed recently. Can I pro-rate the handicap, or should I just ignore it?

    I'm in again. I'll go create my vehicle now. Actually, i may want to wait a little while to do that. I have to make a phone call in another hour and it's outcome may determine what vehicle I enter with.;) I imagine my son will enter again too...sorry about that.:p

    Aaron - you can prorate it. The actual calculation is 3.2%, so your 56% of that would come out to 1.8%. Go ahead and use 2%, then.

    Interesting new rules. The E10 handicap will help.

    Jason, I think that's fine. Just double-check it when you enter the next tank.

    Edit: I checked by changing mine, and it's NOT ok. It rounds the entered number when you save it. That's not a big deal with higher-rated cars like mine, or especially like Sean's, but in your case it's a BIG difference. We'll have to find a solution.

    I'm going to do 2 Division C Entries. The first car is my Focus (what I use for commuting).
    Focus Linky

    The second vehicle will be my wife's family sized Contour SVT.
    Contour Linky

    Both cars will take the E10 hit (it is impossible to find E0 in MI).

    Jason, I've got an answer for you. Since the log here uses a 50/50 average of city and highway, you can do 13/17 or 14/16 and get your desired 15 combined. Take your pick.

    3.2% lower btu * .56 = 1.79% handicap
    3.2% lower btu * .68 = 2.17% handicap

    I still say use 2%. Which, incidentally, will likely kill my chances of beating Larry.

    Since I am in Ca. do I get a 2% handicap?
