Toyota gave birth to the hybrid movement with the U.S. introduction of the Prius in 2000. Sales have been fairly slow, but are expected to take off in the next 5 years as automakers strive to meet higher fuel efficiency standards, according to LMC Automotive.

Driving the news: Hybrids are still more expensive than gasoline-powered cars, but battery prices have fallen enough that it's easier for carmakers to pass along the higher cost to consumers, especially if it's buried among other premium features, says Loehr.

Some Republicans joined Democrats in criticizing President Trump Saturday night for taking executive action on coronavirus aid, with Democratic leaders demanding the GOP return to negotiations after stimulus package talks broke down a day earlier.

Why it matters: Trump could face legal challenges on his ability to act without congressional approval, where the power lies on federal spending. Sen. Ben Sasse (R-Neb.) was the most vocal Republican critic, saying in a statement: "The pen-and-phone theory of executive lawmaking is unconstitutional slop."

President Trump on Saturday signed four executive actions to provide relief from economic damage sustained during the coronavirus pandemic after talks between the White House and Democratic leadership collapsed Friday afternoon.

Why it matters: Because the Constitution gives Congress the power to appropriate federal spending, Trump has limited authority to act unilaterally — and risks a legal challenge if congressional Democrats believe he has overstepped.
