I thought this article about the Volt's design was too interesting to fail to mention. The Tesla is even compared here. I was absoutely shocked at GM's testing of the batteries. Although Tesla is mentioned once in the article, I suppose Tesla didn't see a point in testing its pack 1,000 ways from Tuesday like GM is doing. And I understand Tesla needed more dense packs for range etc...but wow, anyone ought to be impressed with GM, as ugly as their past reporting quarters have been.
