The CAFÉ standards under which vehicles are tested.
Explanation of Solution
CAFÉ stands for Corporate Average Fuel Economy standards. These were established in 1975 to build more fuel-efficient vehicles to increase the overall fuel efficiency of the vehicles. Under the CAFÉ standards, different models from different manufacturers of vehicles are tested for the number of miles they can be driven on a gallon of gas. Then the fuel efficiencies of these vehicles are averaged together. If the average fuel economy of a manufacturer falls below the usual requirement, then the manufacturer has to cover CAFÉ credits or may have to pay a penalty. For this the car makers have replaced many parts of the engine with new technology and techniques to attain higher fuel efficiency in addition to get increased power output. They replaced many manually operated systems with automatic or electronic system to get more fuel efficient vehicles and also get less emission from burning of fuel.
According to estimation, due to CAFÉ standards, the fuel economy will increase nearly to 54.5 mpg between the years 2017 and 2025.
