    I coach full year at the high school in same town, drive my wife to and from the train in the next town, all errands and shopping also within range. Bunch of trips into Boston and "killed" my tank...
    I have 2 gas bars and 55 gas miles left if PiP reading is to be trusted

    all good but having said all that I don't know how Retired4999 managed his recent tank !
    I hit reset last week and even at 100% EV I'm not getting his overall MPGe It is hilly here but still...
    He's gonna keep that Title

    Sounds like retired has a really superb commute/most traveled roads. And I'm guessing with those numbers the man really understands hypermiling, physics, and energy consumption. Ya, he will stay #1 for quite a while.

    What town are you commuting from? We are in Western Mass Springfield area. I do trips to Boston. My 2010 Prius has about 100 miles left on the tripometer with 2 bars left. That's not trustworthy, I go about 50 over that....

    Don't know if the PiP is as (non)trustworthy?

    I live in Hopkinton but I don't commute into Boston - just some visits with my college aged...

    I think the bars are reasonably close since the remaining gas mile read is saying 55 miles to go
    but I won't risk it since its my first tank

    The 10,000 mile interval applies to all Gen 3 Prius cars.

    These look like the output values. How do we know that these are also the regeneration input limits to the battery pack?

    That's a lot of power for a 4.4 kWh battery even for output. I'm surprised the battery can accept regen charge at an 8.6C rate for more than a few seconds (which can be buffered by the electrolyte) without sacrificing battery life over time.

    Has anyone done any real measurements of regen power under different circumstances of speed, braking rate, and duration? How much regen at what rate is absorbed during a long steep downhill stretch in B mode?

    I think the PiP can be an excellent choice for relatively long commutes. The Volt can also be a great choice for ~100 mile commutes, especially if you have the ability to charge at work. You can see this on a post that I am updating daily until I top 1,000 miles for my entry in the "Volt - Top 10 MPGe" list.

    My daily round trip is about 120 miles on average (about 80% highway) and my current status is:

    718.1 miles (88% EV)
    159.30 kWh at 133.78 MPGe EV
    1.68 gallons gasoline at 51 mpg HV
    427 combined MPG
    112 combined MPGe

    Wait, so you're saying yours is a volt right? How often to you refuel with gas?

    It varies. Now that we finally have 240v charging at work (as of 3 weeks ago) I will probably go 2,500+ miles before putting another 6.5 gallons in the tank (about 9.3 gallon theoretical capacity). Back when we had to share a few 120v outlets I could only get half a charge at work and was averaging a 6.5 gallon refill every 1,000 miles or so.

    That's pretty awesome. Overall on Fuelly Volt owners are getting way more MPGes than PiP. Probably because they don't have to travel more than 50 miles before charging.

    The confusing part is your signature. Picture of a volt, yet your vehicle says 2001 Prius. Glad to have Volt owners on here though - just to stir up friendly conversations on plugins. I honestly think plugins are the way to go for overall versatility. Don't know if the electric car can hold the 'charge' otherwise against these vehicles. What if there was a plugin fuel cell lol

    The choices I saw for the car field in the profile were all Toyotas (and maybe just hybrids?). In any case, I still own my first Prius and I also still have my 2004 Prius in the family garage.

    Don't confuse between MPGe and MPG.

    First, there are two types of "MPG".

    1) Traditional MPG - Gas miles driven divided by gallons consumed. 50 miles divided by one gallon = 50 MPG
    2) Plugin MPG - Both electric and gas miles driven are divided by only the gas gallon. 50 miles EV and 50 miles gas divided by one gallon = 100 MPG. This is the over-inflated number that doesn't take account of electricity input.

    There are also two types of MPGe.

    1) Pure electric MPGe - 33.7 kWh of electricity is equivalent to a gallon. Electric miles divided by equivalent gallon. 50 EV miles divided by 0.38 gallon (12.8 kWh) = 132 MPGe.
    2) Composite MPGe - This is the blend of both electric and gas miles taking account of 33.7 kWh as gallon(e). 100 miles divided by 1.38 gallon = 75 MPGe

    There are Top 10 MPGe threads using the Composite MPGe:
    - PiP Top 10 MPGe
    - Volt Top 10 MPGe

    Does one have to fill premium gas in the Volt? That's what I heard. Not sure if that's correct.

    Yes! OK, my wife's a bit more than that but with my liftback there's a definite difference in required throttle positions when she's in the car. It's especially noticeable on hills or accelerating when I'd expect to be able to stay out of the power zone but have to dip into it.

    Yes and no. Premium gas is strongly recommended. The Volt's engine is tuned for premium it so there's a noticeable hit on fuel economy with regular, although the overall cost is a wash. But, given the recommendation and that less gasoline burned means fewer trips to the gas station, people use premium.

    Just out of curiosity, how is your 2001 Prius. What's the MPG have you had to replace the batteries?
