People have hard time grasping how much energy chemical bonds can hold. 15 gallons of gasoline store 500kWh of energy. That is 5 tesla model s worth of energy.

Efficiency plays role for our day to day car tasks, but when you have to deal with external forces or higher requirements of momentum, then you need more energy period. Towing, beating high-speed drag / waves, climbing high, cannot be addressed with smarter design. You need to be able to store somehow enough energy to deal with these external forces / additional required momentum

Yes. However, the Carnot efficiency means that most of it is lost as heat. Suddenly the advantage is not that large anymore.

Not even close. An electric motor is 4 times more efficient than ice. An ice car can easily store 10 times more energy than an electric.

F150 can tow 13,000 pounds and has a 27 gallon tank (almost 10 Tesla’s).
