    I am so glad other people with ADHD can see the insight into trains of thought. Which makes me wonder why we don’t have more vehicles run on Diesel generated Electric power.

      I’ve wondered that too (especially as the owner of a diesel car). My best guess is that hybrid drivetrains come at a price premium compared to plain gasoline engines and Diesels also come at a price premium compared to plain gasoline engines, so trying to put both on the same car would incur a double price premium and not enough people would want to pay it.

        It’s just a diesel range extender, they wouldn’t have to use all that big of an engine. Just like on locomotives, the diesel is just is a generator to power electric motors. No integration into the drive line, the diesel has a generator on it that feeds the batteries.

        One guy put a diesel engine in a Tesla as a range extender and it had a range of over 2,500 miles. It got like a 400mpg.

      A second engine costs more, weighs more, needs more support, and makes everything harder to repair.

      Basically, internal combustion to the wheels is cheaper for the car builders and good enough.

        Diesel electric, not diesel hybrid.

        Diesel generates power that charges the batteries. It would be more expensive than a normal ice car, but it would have thousands of miles of range and get 8-10x the range per gallon.

          Afaik the only difference at the general level is whether the IC engine connects directly to the wheels or not. A hybrid can run on either engine. A diesel electric uses an IC engine to create electricity for an electric engine. So you still need at least two engines, it’s just wildly more efficient. And quite a bit more expensive to produce.
