Yes, an Escalade weighs more than an EV, but no ICE vehicle has to spend extra energy moving several hundred pounds of battery around. EVs, by there very nature, have to do more work moving that battery...meaning there is more energy consumption per mile traveled.
And then you have to take into account the fact that even new, a battery is never 100% efficient....you never get all the energy out of a battery that you have to put in it....and batteries degrade over time and the # of charge-discharge cycles, meaning that as the battery goes through its’ life cycle, it takes more and more energy to drive the same number of miles.
It’s very basic....battery economics will never overcome battery physics.
these EV batteries weigh a lot:
The Tesla Model Y, and it contains a battery that weighs an astronomical 1,836 pounds.
Ford’s F-150 Lightning needs a battery that weighs 1,800 pounds to make it go the distance for drivers.
