Talking about how Chevy plans to offer an 8 year warranty on the battery in the Volt.
I took an Internal Combustion Engines class at Michigan (ME 438) a couple of years ago, and a main concern of the professor was the battery life/robustness over the lifecycle of the vehicle. His example was laptop batteries. They often have crappy lifecycles - they last 6 hours when you buy the laptop, within a couple of years, 3 hours.
Based on this example it seems like hybrid batteries will be similar, they're both pretty advanced battery technology, and i know laptop batteries are getting better, but I think that a diminished range is a real issue with hybrids/electric vehicles moving forward.
Anyone (EEs? CSEs?) know why GM is ready to stand behind these batteries (the single most expensive part of the vehicle) this long? If battery technology is this advanced, I think electric cars might really be the way to go in the future (although you can't get a stick shift hybrid... so that's a no-go for me)
