In an interview with Kelly Blue Book at the 2007 LA Auto Show, General Motors hybrid vehicle expert Stephen Poulos says GM's "next generation" BAS (belt alternator starter) hybrid system will keep the same architecture but use lithium-ion batteries giving it more voltage, higher power and significantly increased capability. Here is exactly what Stephen said at the end of the interview when asked what can we look forward to from GM on hybrids:

I can tell you that we are going at this with a huge amount of commitment. We are hiring engineers as fast as we can do it in the hybrid area. We see a significant growth in the number of models that will be hybridized over the future. Recently we announced, Tom Stevens announced, head of GM power train, that we will have a next generation of our GM hybrid system that's in the Malibu. It will be a higher voltage, higher power system. Same basic architecture, motor generator with a belt drive. Significantly increased capability using lithium-ion batteries. So that's one hint out there of what's coming ... but those will be going in a lot of places.

Just another hint that GM is serious about new battery tech, as if we needed another one:

• First prototype Chevy Volt battery packs arrive
• GM and Johnson Controls say the government must help develop next-gen batteries

People have a variety of reasons for buying hybrid vehicles, one of which is saving money on fuel – they go green to save some green. For others, there's the sincere motivation of environmental stewardship. And for others still, though they may be loath to admit, there's an undeniable ego aspect – think of that hybrid badge as the automotive equivalent of a polo pony on a collared shirt.

The one "problem" with hybrids is that they cost more than non-hybrid cars – you pay a premium for the technology. That added cover charge may be enough to keep some from getting past that green velvet rope. To try and address this, General Motors has developed its Green Line "light" hybrid system.

GM was obviously watching closely as other companies like Toyota, Honda, and Ford made waves and grabbed headlines with their high-profile hybrid vehicles. In response, GM earmarked Saturn to be the brand to offer a mass-market hybrid, and it would go after customers by marketing an inexpensive alternative to other, more costly hybrids. The result is the 2007 Saturn Vue Green Line.
