LOS ANGELES - Auto makers will roll into the Los Angeles Auto Show with a new lineup of concept cars powered by alternative fuels. But activists complain the companies are still moving too slowly to curb the nation’s dependence on foreign oil. General Motors Corp., Ford Motor Co. and BMW AG will unveil vehicles that run on hydrogen. Other companies, including DaimlerChrysler AG and Volkswagen AG, will show vehicles powered by E85 ethanol, electric-gas hybrid engines, biodiesel, natural gas and low-sulfur diesel fuel.
