I did not bookmark the article, I was just randomly searching. As I recalled the articles and pages that I read, they were measuring man-hours on the assembly line per vehicle at some fraction near 40 hours, usually under.

The same articles talked about overhead based upon superior benefits, and pension contributions.

If it matters to you, I can take the time to try again to find the articles, and recheck the figures. (I can't re-check the browser history, since I no longer have access to that computer.)
