How much does driving fast cost?

That is equivalent to a 54 cent per gallon increase in fuel costs.

Pushing air around actually takes up about 40% of a car's energy at highway speeds, according to Roger Clark, a fuel economy engineer for General Motors (GM, Fortune 500).

The math:

• If a car gets 28 mpg at 65 mph, driving it at 75 would drop that to 24 mpg.
• Fuel costs over 100 miles, for example - estimated at $3.25 a gallon - would increase by $1.93, or the cost of an additional 0.6 gallons of gas.
• That would be like paying 54 cents a gallon more for each of the 3.6 gallons used at 65 mph
• the old national 55 mph speed limit, instituted in 1974, was a response to the period's energy crisis.
