Automotive News explains, “A bill to make fuel-efficient three-wheeled vehicles eligible for federal funding now available to automakers and their suppliers has passed Congress and is headed to the White House for President Barack Obama’s signature.” The bill will provide Energy Department funds to startups like Aptera Motors and Elio Motors, which have developed experimental three-wheeled vehicles that reportedly get significantly better fuel economy than most of today’s passenger cars. In some cases, the vehicles are electric.

Autoblog adds, “three-wheeled vehicle platforms sometimes have the potential to use less energy to operate than their four-wheeled siblings, though some still question the inherent safety of such designs. Assuming the bill passes the President’s desk, any manufacturer of enclosed three-wheeled vehicles that can carry at least two adults while returning at least 75 miles per gallon will be eligible for funding, though the DOE will still approve applications on a case-by-case basis.”
