From USA Today, even though it came out yesterday:

Instead of shoehorning the electric powerplant into a conventional GM compact-car platform, the next Volt will be purpose-built. That will allow the ability to better package the batteries and other specialized components, says Mark Reuss, president of GM North America.

Shows my ignorance, I thought it was purpose-built. The Honda Civic Hybrid isn’t purpose-built, and it doesn’t come with a premium price tag.

To me, this reads like a book coming out in hardcover for the people who really want it, then releasing the paperback for everyone else.

And now I’ve exhausted all my car knowledge, and have lost my train of thought.
