    Plus saving pennies on gas? Sorry but that is the nature of a gas vehicle. They have a really short window of mpg between granny driving and rocketing at 75+.

    I calculated it plenty. when driving 65 MPH, the air resistance is good enough for you to get 28 to 30 mpg. Let’s keep it simple and just say 30 mile trip. At 75+ MPH, your efficiency starts taking a major hit. You will likely be traveling at 25 MPG. That is a +20 percent increase on gas consumption. If you think of it, that is a consistent 18% to 20% loss on gas.

    At $3.50/g(my current market) with an additional 20% increase of fuel usage so, $3.50 * 1.2 = $4.20

    For a 15 gallon tank, you are burning $63 worth of fuel on average.

    While on electric vehicle, it depends on types of charging. If you have solar then it’s free, I don’t. If you have simple home charger, my current rate is 20 cents per kWh. If you fast charge, then it is 50 to 60 cents per kWh.

    Most of the time I am getting between 3.5(above 65 MPH) to 4.5(below 65 MPH) Miles per kWh. With 30 mile trip that is 8.57 kWh to 6.67 kWh usage. This helps translate to cost of gas because 1 gallon at 65 MPH is about 30 miles. So if I do only home charging that is $1.70 to $1.33 for electric. Fast charging that is about $4.70 to $3.67 for just the 30 miles.

    15 gallons of gas can get you 375 miles at 25 MPG, or 450 at 30 MPG. Remember $63 for driving at 25 MPG vs $52.5 for driving at 30 MPG. With electric driving, to get 375 mile at 3.5 miles per kWh or 450 miles at 4.5 miles per kWh. we can translate them over.

    (Above 65 MPH) 375/3.5 = 107.15 kWh * $0.20 = $21.42
    (Below 65 MPH) 450/4.5 = 100 kWh * $0.20 = $20.00

    (Above 65 MPH) 107.15 kWh * $0.55 (fast charge) = $58.92
    (Below 65 MPH) 100 kWh * $0.55 = $55.00

    See now how crazy expensive that becoming for gas while electric is barely taking a hit? Makes little difference for electric vehicles, but gas? That is not pennies.

    Let me tell you I was being very generous with the MPG figure. I looked at family members MPG tracker on their car and they are getting 20 to 25 MPG, but I was being generous because isolating highway only driving is mostly a generous driving situation for a gas vehicle.

      Too bad going electric is so cost prohibitive, living situation prohibited, and so on… Hard to put a charger in an apartment for example.

        It is just plain math, we all living with what we can do. If you are stuck with gas, I hope you can save up cash for a house. My sister finds houses for rent that are about the same rental cost as an apartment. I also found apartments that have a garage for me to park into. Similar rent cost but added 150/m probably not going to save money on gas but at least there are options my family has found to accommodate our needs.

        At the end of the day, driving electric or riding my bike, I save enough cash that I am able to save 150 to 300 a month.

      I tested this on my car as well. I gain about 3 MPG by using the cruise control and adhering to the speed limit vs. Just driving how I want. It’s not worth the difference. Changing to shitty tires was a bigger hit to my MPG than that.

        That is pretty significant difference between what I had experienced, i guess not much more mpg for your vehicle for you vs my own eco vehicle. sorry your car doesn’t experience more efficiency gains. I am good where I am at. My suggestion wasn’t to stop you from achieving what would be higher speeds but rather you will feel the gas pedal be much harder to push. That is all
