    Some quick math from this https://www.realclearscience.com/articles/2022/09/22/how_expensive_is_it_to_charge_an_ev_in_europe_and_is_it_really_cheaper_than_gas_854618.html#!

    Puts slow charging at 1/4 the price of gasoline. That’s substantial.

    Other searching says average of 18k km per year in Europe. With 6 l/ 100 km average age 1.76€/ l, gasoline costs €1,901 per year. Vs €475 for electricity. Saving €1,426 a year (1,527 US) Do that for 10 years and that’s €14,260 saved ($15, 270 US). I can only expect that savings will increase as gas prices go up.

    As for maintenance anything with a timing belt is going to have a massive maintenance cost. There’s just no comparison in the design of these things. Electric motors have such a simple design. ICE cars have oil changes, transmission oil changes, coolant changes, spark plugs, starters, 12 v battery, accessory belt, timing belt, alternator. Yes EV’s have a 12v battery and coolant but these are not taxed nearly as much as ice cars.

    EV motors are so simple they’ll handily outlast ice engines. And no transmission either. Boy if you’ve ever had transmission problems you’d never want another, EVs don’t have that. Tesla used to be on about a million mile drivetrain warranty because it really should be feasible. Ice cars can’t ever get that (on average).

    Batteries yeah we’ll see how well new ones last. For a million miles you’ll go through a few batteries, which get better each time.

      Alright, time to do actual numbers.

      18.000 is heavily influenced by all the people driving >100.000 km per year, unless that’s the median, not the average. I’m far below 10.000 and still waiting for it to be worth it for me. I’ll calculate with 10.000 for now.

      Modern ICE cars need far less than 6l. A modern VW Golf for example only needs 4-5 l per 100 km (4.5 avg, and yes it actually is that low, I’ve been driving a modern VW Golf at the military a few times and have tracked my average fuel consumption there).

      Gas currently fluctuates from 1.525 to 1.599 in my area, so I’m always only filling the car on Monday mornings when it’s 1.525.

      10 000 * 1.525 * 4.5/100 = 686.25€ per year.

      Even if there’s a major crisis like when the war in Ukraine started and the price goes up to 2€ per liter for some time and I’m at 1.8€ average for the year (I have never had such a high average so this is really stretching it), we get 10 000 * 1.8 * 4.5/100 = 810€ per year. Worst case, never happened before scenario.

      Economic modern EV need ~16 kWh per 100 km. The average price per kWh at home is 0.2€ in my area.

      10 000 * 0.2 * 20/100 = 400€ per year.

      = 286.25€ (410€ worst case) per year saved (purely for moving the car), assuming I always charge at home. If I do longer trips on holidays and have to charge somewhere else that gap gets lower.

      Even when adding less taxes, less repairs (but modern engines really don’t need much repairing, even though they’re much more complex than electric motors and wasting more energy) it will still will take a long time to break equal (probably never because I need a new battery before breaking equal).

      If I have an average of 10k km per year that’s 16.200€ for 200.000 km over 20 years with an ICE car at 1.8€/l (higher average than I’ve ever experienced) or 6.400€ for the same with an electric car at 0.2€/kWh (which is below my average of the last two years). Ignoring inflation for simplicity, just assume my salary goes up with inflation so percentually it stays the same.

      If I need a new battery (10.000€, actually more but I’ll just say 10.000 for now since they’ll likely go down at some point) every 10 years then I’m just about to break equal after 20 years, right before going negative again by buying another battery.

        You have an incredibly adversarial tone with that “actual numbers” as if mine aren’t, so I’m not going to continue.

        But I will point out I’m using averages and you are cherry picking low mileage per year, low fuel consumption, and low gas prices. And I’m guessing funny electric numbers to change 1/4 the cost of gas to nearly 2/3 the cost. And funny enough you are combining low mileage per year with moderately-high battery replacement rate. You are picking and choosing.
