One Million Plug-in Cars by 2015? [Update]

The papers mention that since 2008, Barack Obama has consistently promoted the goal of having 1 million advanced technology vehicles on U.S. roads by 2015. The number refers to plug-in vehicles that use grid power, stored in lithium-ion battery packs, to operate their electric traction motors. Regular hybrids like the Toyota Prius don´t do that. The all-electric Nissan Leaf, the series hybrid Chevy Volt, and an upcoming plug-in hybrid version of the Prius do. But recent analyses by experts and industry analysts differ sharply on whether that number is achievable. Many say that high cost, limited range, a nascent supply chain, and consumer hesitancy will make 1 million vehicles in 2015 impossible.
