What percentage of car get 40 kml¹ or more? In times of scarce energy resources, a competitive advantage is given to an automobile manufacturer who can produce a car that has substantially better fuel economy than the competitors' cars. If a manufacturer wishes to develop a car that beats 95% of the current compacts in fuel economy, what must the petrol use rate for the new car be?
