President Trump is expected to announce Wednesday that his administration plans to review new, tougher fuel-economy standards, a move likely to be cheered by U.S. automakers.
If the review eventually results in the standards being lowered, automakers potentially wouldn’t have to make as many cars with advanced carbon emission-cutting technology like hybrids, electrics and hydrogen fuel cells in order to hit the minimums. Though cleaner, they are more complicated to make, can be less profitable and generally carry higher prices.
