GM is working on a second generation of mild hybrids to be available in the third quarter of 2011. They have a mid-sized sedan (they won't say which) for the US and another in China. The source (via Autonews) was Larry Nitz, GM executive director of hybrid and electric powertrain engineering.
That's great news and important if GM wants to meet the upcoming guidelines on fuel efficiency for their fleet of cars in the US. Not every car can be a hybrid or a plug in the coming years. Mild hybrids give a much smaller boost in fuel efficiency, but the cost to implement it is also a lot lower. A start-stop (gas engine turns off at stop lights) system paired with regenerative braking and a much smaller battery pack and you can boost acceleration using electric power rather than more gasoline.
More than likely, the more powerful part will come from a new generation of battery pack (maybe lithium-ion?). Nitz said the benefit would be about 20% in fuel economy.
