[QUOTE="Twin_Sparx, post: 114573, member: 2404"] Again, I would like to reiterate that I'm not being judgmental on this whole issue. Its simply from experience and knowledge gained from most structural engineers who have had the previlage to be working on crashworthiness. Also, as most of this is confidential, I can only go so far as to give a brief overview. Most vehicle manufacturers have different approaches in designing their structures for crashworthiness.... and these are usually trade secrets. A good and obvious example is Volvo with their boron-steel A-pillars.... AND, if you guys have been observant, check out the new range of BMWs - you'll consistently see a V-shaped cross-tube connecting the front shock towers to the cowl/dash panel. To the layman, it may seem like a connection to improve torsional rigidity - to our eyes, its also to enhance frontal crash performance. Another trick BMW uses for lateral / side impact would be door catchers (a little L-shaped bracket on your door - go check it out!! :D ) - and a huge bulge on your front seat base, outboard side. Again, go check it out....very obvious in the 5. Coiincidentally, I thought up both this solutions for one of the cars I was involved in, THEN discovered BMW had it in the new 5 when it was launched!!! Not kidding!! Suppose it was merely a logically thing to do. Anyway, this is NOT a matter of who's right and wrong.... or whether Bilsteins are better than Konis. No, no, no,its not a comparison, ok! ;) Anyway, I'll get down to it tonight as today has been a hectic day. :beaten: Hope to have stirred up some interest! [/QUOTE]
