Sweden-based Volvo Cars announced that starting in 2019 it will only manufacture vehicles that are either all-electric or hybrids, making it the first mainstream automaker to phase out models that operate just with traditional gasoline- or diesel-powered internal combustion engines.

That will also make it the first among traditional automakers to offer a line that would provide little revenue into the U.S. Highway Trust Fund, as it is currently designed. And such developments could add to pressure for Congress to find ways to shore up the trust fund in any infrastructure investment plan or tax reform that lawmakers consider.
