* Automotive Diesels are in the neighborhood of 42% Brake Thermal Efficiency ( BTE ), wasting 58% of the fuels energy right off the bat.
* A gallon of Diesel has been assigned an equivalence of 40.108-kWh electrical energy, so that would have fallen to 28.877-kWh leaving the shaft of the engine, and entering the alternator
* Alternators are very efficient. Allowing a 98% efficiency, a Tesla would 'see' 28.3-kWh coming at it, for each 40.108 kWh-e gallon of fuel burned.
