Stan Moneymaker has been informed of a major automobile manufacturer?s plan to conserve on gasoline consumption through improved engine design. The idea is called engine displacement, and it works by switching from 8-cylinder operation to 4-cylinder operation at approximately 40 miles per hour. Engine displacement allows enough power to accelerate from a standstill and to climb hills while also permitting the automobile to cruise at speeds over 40 miles per hour with little loss in driving performance. The trade literature...
