Component shortage may threaten GM hybrid plan

In its viability plan submitted to the U.S. Treasury, General Motors promised to boost the number of hybrids in the company's lineup to 26 models by 2014, up from eight today. Although there are no concerns that the technology would be ready, there could be shortage of certain parts. According to what Tom Stephens, GM executive vice president of global powertrain and global quality, told Automotive News: "There are a lot of ifs, ands and buts associated with that. We will have all of this developed, but depending on component availability, we may do one thing or the other." Parts that could be in shortage include lithium-ion batteries, and some yet-to be developed electric motors. The Saturn Vue Two Mode hybrid, for example, has been delayed already. Nevertheless, GM plans three versions of its hybrid powertrains: mild hybrids like those used in the current Vue and Malibu hybrids, and two iterations of the Two Mode hybrid, one for rear drive cars and the other for front drive vehicles; the latter could also come with plug-in capabilities.
