Automobile Drag Coefficient

Automobile Drag Coefficient

The drag coefficient is a common metric in automotive design pertaining to aerodynamic effects. As aerodynamic drag increases as the square of speed, a low value is preferable to a high one. As about 60% of the power required to cruise at highway speeds is used to overcome aerodynamic effects, minimizing drag translates directly into improved fuel efficiency.

For the same reason aerodynamics are of increasing concern to truck designers, where greater surface area presents substantial potential savings in fuel costs.

Famous quotes containing the words automobile and/or drag:

    For a woman to get a rewarding sense of total creation by way of the multiple monotonous chores that are her daily lot would be as irrational as for an assembly line worker to rejoice that he had created an automobile because he tightened a bolt.
    Edith Mendel Stern (1901–1975)

    I know those little phrases that seem so innocuous and, once you let them in, pollute the whole of speech. Nothing is more real than nothing. They rise up out of the pit and know no rest until they drag you down into its dark.
    Samuel Beckett (1906–1989)
