We've known it for a while, and automakers have all but given in to the governmental and consumer pressure by committing to adding battery-powered cars to their fleets (or, in some cases, completely committing to fleet-wide electrification). That hasn't exactly gone over smoothly with big oil, and now the EPA's new ruling on tailpipe emissions—despite being more lenient on acceptable levels of pollutants—could prompt a long legal battle.
