PICKUP TRUCKS FUEL ECONOMY * USA: New rules
* DC - What do the new truck regulations mean for pickups?
... Fuel economy for heavy-duty pickups will significantly increase with the new rules, but not nearly as much as for light-duty pickups. The figure below shows the baseline 2014 data for heavy-duty gasoline and diesel pickups, and their projected increase in fuel economy to comply with the proposed 2027 rules. The figure also shows the comparable data for large body-on-frame pickups that are regulated as light-duty vehicles, to provide additional context. As shown, heavy-duty gasoline pickups increase from 14 mpg to 19 mpg, and heavy-duty diesels from 17 mpg to 21 mpg on the regulated test cycle. Note that we also showed (on the right-hand-side vertical axis) the approximate fuel economy as seen by consumers, assuming vehicles get 20% lower fuel economy in the real world...
(Model year 2014 and regulatory 2027/2025 fuel economy of pickup trucks: heavy-duty gasoline, heavy-duty diesel, and light-duty gasoline)
... With these new proposed standards, the heavy-duty pickups in 2027 will not meet the fuel economy of today’s large light-duty pickups, which is 24 mpg on the test cycle. Note that, although these light- and heavy-duty fuel economy values are shown together for context, they have different testing protocols. The light-duty vehicles are tested with an additional 300 lb above the empty weight, as compared to 1,000 to 2,000 typically for the heavy-duty pickups... There’s no mistaking that the regulations will do a lot for heavy-duty pickups and vans. However, it is safe to say that the proposed rules do not embrace the full technology potential that is available...
