How do car manufacturers determine MPG?

Vehicles are tested at a top speed of 80 mph in order to calculate the highway mpg estimates. EPA utilizes five test cycles to represent real-world driving conditions. The remaining three tests are designed to simulate stop-and-go city driving, high air conditioning use, and driving in cold temperatures.
