On average, every single mile per hour increase over 50 mph reduces your fuel economy by .1 miles per gallon.
Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.
Did you know? Cruise control technology was originally invented in 1788 by James Watt and Mathew Boulton to help control steam engines. Thanks are due to Ralph Teetor, a blind mechanical engineer, who refined refined the technology in 1945 to invent today’s modern automotive cruise control. Thanks to Ralph, this handy feature now makes long drives easier, keeps our speed constant, and even helps us save money.
