This is partly due to the fact that the EPA changed the test:

Regulatory Announcement: EPA Issues New Test Methods for Fuel Economy Window Stickers | Fuel Economy | US EPA

Under EPA’s new methods, the new fuel economy estimates for most vehicles will be lower. This is not because auto makers have designed the same vehicles to be less fuel efficient – it is because our new test methods take into account factors that have been missing or not fully accounted for in the current tests. Because some vehicles are more sensitive to these factors than others, the impact of the changes will vary from vehicle to vehicle.
