Gasoline vs Battery Energy Density Explained

I thought Engineering Explained did a good job of explaining energy density of both gasoline and battery capacity. This video also gives a good insight of the technical and the economics challenges Electric vehicles face and why it makes good sense to continue to improve the Internal Combustion engine.

Video 2 explains the efficiency of the two different sources of energy.

  • What you don't see are the EPA projected mandated MPG numbers 10 years into the future. They are unobtanium with any version of IC engines. Nobody knows how to get there.

    IMO it makes good sense to continue improvement of both.


    I suspect some automakers don’t have budgets to support both. This is why some of the mergers are happening.


    And this is yet another EPA mandate that ends up doing more harm than good. One of the reason why these companies do not have the budget to do both is because they are having to pay hundreds of millions for carbon credits because the EPA CAFE fuel economy regulations increased sharply at too high of a rate for the available technology. Instead of taking a little more time and money to invest in BEV's or other technology along their ICE power plants at a gradual rate, the automakers had to scramble to improve only their ICE engines or pay hefty fines leaving little money for other investments. This is on top of stricter safety regulations that also requires money.

    Although, if you look at where the money is going with these carbon credits, it starts to become clear why the corrupt EPA made this ponzi scheme.


    I agree.... and these auto manufacturers are passing along those costs to the customer when they can.

    That's a good point. In the early 1900's electric and gasoline vehicles were common. Then the gas engine won and manufacturers concentrated on improving the engines.

    I wonder what would have happened if they had concentrated on improving batteries? I know the technology was not available at that time.
    I guess the same can be said for nuclear powered aircraft?
