For the government, the future of fuel economy is up in the air.
Before leaving the White House, the Obama administration did their best to make their Corporate Average Fuel Economy (CAFE) standards the new permanent standard. But the Trump administration quickly announced that once a full review of CAFE standards was performed, they would probably relax the 2025 targets put in place by the previous administration. That assessment and recommendation is coming soon.
It stands to reason that relaxed CAFE standards would decrease the demand for aluminum—the metal many manufacturers adopted in order to make vehicles lighter and, therefore, more fuel efficient. But that’s not the case.
