    Here is a quick run down of how the Prius and a Plug-In Prius compare.

    Car: 2006 Toyota Prius
    Conversion: Hymotion in 2008

    Total miles driven: 56823.2
    Miles driven Prius: 28665
    Miles driven Plug-In: 28158.2

    Prius Data
    Gas used: 501.36 Gallons
    Gas cost: $1485
    Average MPG: 57.2
    Average CPM: $0.052


    PHEV Data
    Gas used: 228.56 Gallons
    Gas cost: $689.10
    kWh used: 3884.5kWh
    kWh cost @ $0.08: $310.76
    Total fuel cost: $999.86
    Average MPG: 123.2
    Average MPGe: 81.8
    Average CPM: $0.036


    Other data
    Total gas used: 729.92 Gallons
    Total gas cost: $2174.1
    Total Fuel cost: $2484.87
    Average gallon gas: $2.979

    Savings over 25MPG car
    1543.01 gallons of gas saved
    $4285.17 in gas saved
    Projected savings @ 100k miles: $8088.12 ( This continues to go up as I drive with the Hymotion battery. I should reach $10k saved by the time I reach 100k miles.)



    My guess is that depending on what your commute is you should see similar results with an official plug-in Prius.

    I really don't have anything else to add. If you have any questions I'll try to answer them.

    The only real problem I've had was the DC-DC converter failing. Other things were the low 12v issue, had to have them reverse the fan wires as it was installed wrong at the factory, and a loose wire on the wire harness which I fixed myself. Other than that it has worked great.

    So the plug in saves about 1 - 36/52 = 31% of fuel.

    If gas stays at $4, and Prius mpg = 50, it will save $4*0.31 = $1.24 for every 50 miles,
    or $248/10K Miles
    or $4800/200K Miles

    The pay back time is a little too long for most people I guess...
