    On a percentage basis, if there is one occupant in an automobile, only about 0.5% of the total energy used is used to move the person in the car, while the remaining 99.5% (about 200 times more) is used to move the car itself. An important driver of energy consumption of cars per passenger is the occupancy rate of the vehicle.

    For instance, a small car might need only 10–15 horsepower (7.5–11.2 kW) to cruise at 60 mph (97 km/h). It is likely to be geared for 2500 rpm or so at that speed, yet for maximum efficiency the engine should be running at about 1500 rpm (gasoline) or 1200 rpm (diesel) to generate that power as efficiently as possible for that engine ...
