You fail at reading comprehension. One of your own links referred to a later Ducker report.
consequently we’ve seen a great deal of growth in the Advanced High-Strength Steel market. A Ducker study conducted in North America reflects this increase in AHSS usage. As you can see here, the study data shows the dramatic upward trend for Advanced High-Strength Steel content in vehicles and what is anticipated out to the year 2020.
See the number for 2009? 150lbs. Fleet average weight of a passenger vehicle in 2009? Just over 4000lbs. That's 3.75% of AHSS the remainder of the 11% is medium strength steel.
it's funny you mock me about reading comprehension, then post that...you don't talk about the entire weight of a vehicle (in your example, 4000 pounds)...the car seats, engine, transmission, etc have no effect as the HSS are not used there...the newer steels are used in structural components and are now used in things like suspension/steering components too...i never said 50% of the weight of the car was HSS, although you just insinuated i did...my comment regarding the percentages was to show where it has displaced standard steel in the vehicles, which has helped reduce the weight (or keep it off) as it is increasing in its use substantially in the last few years (and will continue going forward)...in many cars today, it means keeping off 150-200 pounds, and in some case, could be upwards of 400 pounds...in the coming years, you may very well see it used on body panels as well (or perhaps some other lightweight composite) to help keep weight down as emissions regulations and fuel economy requirements get more strict.
either way, i'm not really sure why you are arguing about this...you have taken a harmless kudos post from me (to Mazda, Hyundai and Honda) and want to pick it apart...debate with me all you like, but don't cry about the thread being dragged off topic, when you are the one doing it.
