The reason for this? The Golden State. Just after last year's 2016 CAFE numbers were announced, California said it would work on "a much more stringent standard" for 2017 and afterward. Automakers urged the feds to head the California Air Resources Board off at the pass in order to stay ahead of state initiatives, thereby quashing the chance that different laws would hit the books.
The EPA and DOT have just gotten to work on crafting new standards, so it will probably be another year before new numbers come out. For you folks with large-capacity, high-horsepower engines, you might want to take this chance to rev 'em if ya got 'em.
