fuel efficiency
The efficiency with which a motor vehicle converts energy into movement.

Not necessarily equivalent to fuel economy, in that one vehicle might have better technology and therefore be more efficient than another, but if it is much larger and heavier than the other vehicle, it would have poorer fuel economy.

luminous efficiency (s) (noun), luminous efficiencies (pl)
The ratio of the radiant energy sensed by the average human eye at a particular wavelength to that received: The ophthalmologist, Dr. McMahon, was requested to determine the luminous efficiency of his patient, Mr. Jones, who appeared to have difficulty perceiving particular colors.

mechanical efficiency
1. The ratio between the brake (useful) horsepower and the indicated horsepower of an engine.
2. The measure of the effectiveness with which a system performs.

It is stated as the ratio of a system's work output to its work input.

In a theoretically frictionless, or ideal, machine, the work input and the work output are equal, and the efficiency would be 1, or 100%.

efficiency
The fraction of the energy that a machine uses effectively compared with how much is put in.

A typical gasoline engine is 30 percent efficient, so it uses 30 percent of the energy in the gasoline to move the car forward and wastes the other 70 percent, mostly as heat.
