The Prius Prime is a dual fuel vehicle, able to run 100% on Electric, or 100% on gasoline, or a computerized blend in-between. This presents me a great opportunity to be able to do a direct comparison with the same car of an EV engine vs an ICE engine.

  • Toyota computer claims 3.2mi-per-kwhr.

  • Kill-a-watt (https://en.wikipedia.org/wiki/Kill_A_Watt) claims 2.2mi-per-kwhr.

  • Additional 1.5% losses should be assumed in the wires if you wish. (120V drops down to 118V during charging, meaning 2V of the energy was lost due to the resistance of my home’s wires).

  • Level 1 charger at home (known to be less efficient).

  • Toyota computer claims 53miles-per-gallon (American Gallon).

  • I have not independently verified the gallon usage of my car.

  • 295 miles driven total, sometimes EV, sometimes Gasoline, sometimes both.

  • 30F to 40F (-1C to 4.5C) in my area this past week.

  • Winter-blend fuel.

  • 12.5miles per $electricity-dollar (17.1c / kw-hr home charging costs)

  • 17.1 miles per $gasoline-dollar ($3.10 per gallon last fillup).

If anyone has questions about my tests. The main takeaway is that L1 charging is so low in efficiency that gasoline in my area is cheaper than electricity. Obviously the price of gasoline and electricity varies significantly area-to-area, so feel free to use my numbers to calculate / simulate the costs in your area.

There is also substantial losses of efficiency due to cold weather, that is well acknowledged by the EV community. The Prius Prime (and most other EVs) will turn on a heater to keep the battery conditioned in the winter, spending precious electricity on battery-conditioning rather than miles. Gasoline engines do not have this problem and remain as efficient in the winter.

    Dude genuinely sees flying off the handle as the right way of responding to disagreement. He explains that people who criticise him are iredeemably dishonest so debating them is a waste of time and he finds it ends the discussion much quicker if he puts a lot of anger and insults in.

    Straight up!

    I’ll paste it on case he deletes it.

    You want them to take it back. Do so.e research, and prove them wrong. Otherwise, stop shouting.

    BTW: Seriously, you seem naive to me so let me give you a serious protip.

    If someone thinks you are biased on the internet, and you owe them nothing (not like a close friend or a family or something), you STOP TALKING WITH THEM BECAUSE ITS A WASTE OF TIME. And I’ve found that shouting, and direct insults, is the fastest way to make it clear that I’m ending the discussion.

    Again: don’t waste your time trying to prove yourself against baseless accusations on internet. Its not worth the hassle. If you find yourself doing that, you are the one who will get stressed out in the long term.

    So I reject your advice and instead replace it with the exact opposite. Get angry. Shout, end the discussion. Then move on with your life. The discussion has been blown up, so its easier to move on. Don’t lol “do research” on behalf of other people who don’t give two shits about you and drag on the unnecessary discussion for days. They never were going to believe you anyway, because they thought you were biased from the start.

    He lives by the anger and insults advice, I can attest, but in terms of ending the discussion, and moving on with his life, he’s not so good at that part. I believe him when he claims to refuse to do any balancing tests, but not for the reasons he claims, he just doesn’t want to know about data that paints a different picture.
