As an introduction,
please have a look at the following 2 videos that highlight the SIPS seat
rails/tubules and crash box that I believe are present in the xc90 and some
other recent volvo models.

It seems that volvo designed the XC60 without these horizontal rails in the
seats and with no such internal crash box. The video shows what I am talking
about. You can also see that the XC90 DID have this feature in the other
video. Why did they give up on such a seemingly smart system ? I reached out
to Volvo and they dodged the question altogether in the letter they sent me
. Very disappointed in that interaction. What's your take?

(Notice that he says that ALL the yellow is Boron steel - Is this really
true, or was he confused ? I believe he is a design engineer, not a safety
engineer - other documents (see links below to a few pictures) seem to
contradict his statement - Though I'm sure the yellow is strong steel - I do
NOT believe that ALL that yellow is boron)

In any case, the following video is proof of the strength of the xc90 cage.

Can you share with use where you were able to look up the relative amounts
of Boron in different vehicles ?
I noticed that the Porsche Cayenne seems to have a lot of Boron in its side
structures and throughout.

Surprisingly, I have not been able to find ANY evidence that Mercedes and
Audi use Boron in their SUVs. Could this really be ? Seems unlikely based on
the roof strength tests conducted by NHTSA where Mercedes' roofs are 50%
stronger than the nearest competitors, including Volvo. Mercedes for some
reason makes note of their use of Hydroformed steel? Why? Is it stronger
than Boron ? Is anything stronger than Boron that is in use in vehicles
today ?
If you were to rank SUVs by the amount of Boron in their Safety cage
structure, who would come in 2nd, 3rd, 4th, and 5th place for you?
Where do the XC60, Mercedes GL, Mercedes ML, Lexus LX550, and Porsche
Cayenne fall on your list ? Would you consider a heavy non-SUV vehicle for
your family members?
Thanks in advance ! |
