U.S. automakers also need to develop plug-in hybrid vehicles to boost fuel economy and reduce carbon dioxide emissions, he said.
“Plug-in hybrids: that’s the wave of the future, not hydrogen,” Iacocca said.
Proposed plug-in models would use advanced lithium-ion batteries recharged at household outlets to provide extended electric motor driving range before an engine powered by gasoline or other fuel engages.
Toyota this month began testing prototype plug-in Prius hybrids at the University of California’s Irvine and Berkeley campuses. GM has said it wants to sell a version of its Volt plug-in with at least 40 miles (64 kilometers) of battery-only range by as early as 2010.
