    This is just an "approximate" calculation to compare the driving cost in each mode

    Pure HV Mode
    $3.5/Gallon
    60 Miles/Gallon
    $ per mile = 3.5/60 = $0.06/mile or $6 for 100 miles.

    Pure EV Mode
    $0.20/kWh
    25 miles using about 7 KWh (which is about 80% of the total capacity of 8.8 kWh traction battery)
    $ per mile = (0.2/25) x 7= $0.06/mile or $6 for 100 miles

    There are many parameters that are constantly changing and would affect the outcome.

    Yeah, very close but at that rate of gas and electricity, EV is still slightly better. It is known that at the wall by OEM L1 takes ~6.5kWh to do 0 to 100% full charge. Using EPA standard 54mpg and 25miles EV range, or from most reported cases of PRIME efficiency, your EV range is about 1/2 of distance the car can drive with 1 gallon of gas.

    In my case the EV range in summer increase to 35 miles, but so does mpg on HV to ~70mpg. During winter EV range is down to 22 miles but so does mpg to ~44mpg. Use this 1/2 gallon HV distance for a full EV range rule,

    If you multiply the cost of electricity $0.20/kWh x 6.5 kWh= $1.30
    If a gallon of gas is $3.50 (meaning $1.75 for a half gallon distance), then you are better off with EV economically.

    For me, here in Austin TX, the numbers work out to about 4c per mile on gas (in town; more like 5c/mile on the highway) vs. 2.5c/mile charged from home.

    Austin Energy also has a program where (speaking in round numbers), for a $1/week, you can charge all you want around town, which thankfully includes my place of work.

    For me, miles driven that way come out to around 0.5c/mile.

    Arguably though, what’s even more valuable here is that I’m putting hardly any wear on my ICE, so at age 58 now, there’s a fair chance *I* will expire before our Prius Prime does!

    My electricity ~$0.12/kWh and my car has cost me on average about $0.031/mi in fuel (electricity/gas).

    5 cents per key at home here in Reno. So around penny per mile.

    You are spending only about 1/2 of what I'm spending here in SoCal - $0.06/ mile is fuel whether electric or gas...
