Well they may have done it right finally. You need to remember test mileage versus actual mileage has historically been wrong. It was only recently since they updated the mileage test to maintain an average speed of 50+mph. The old tests from the 80's through the 90's had an average speed of 48.x mph. There was the issue. if marketing wanted to push a car "highest fuel economy in the class, they vehicle had to be engineered to beat its competition in the standard test. Meaning the best mpg was acheived at unrealistic driving conditions. There were many vehicles that out did their mpg rating in the real world because of the car was built for real world conditions.
The next standard test may giving the cruze 36mpg, but true world driving may be 40+ at reasonable 60-65 mph highway driving.
