This article comes from "pickuptruck.com" and is mainly about how well GM trucks are doing in the marketplace, this link is to page 3 of 6. It talks about GM's future plans to increase fuel economy, one of them being going from a hydraulic steering to hybrid technology electric steering. This may mean going to a 42-volt power system for trucks for such a system, not just for the hybrids (which I know nothing about).
The fuel economy part starts at the second paragraph below the picture in the article.
