Re: [DML] The COMPLETE DeLorean crash test videos, report and more.

High torsional rigidity is a good thing, as it makes the suspension do most of 
the work and typically leads to a car with more predictable handling.  A 
flexible frame can work as long as the designers take that flexibility into 
account when they are designing the suspension.  Lotus had been working with 
backbone frames since the 60's in three different applications (the Europa, Elan 
and Esprit), so they knew the math.  A key element in a backbone frame 
construction is the rest of the bodywork, as it provides some of the structural 
rigidity in the assembly.

I think I would rather have a frame which is flexible than one that is too
rigid. From what I understand, a vehicle frame doesn't just carry the load
above it -- it absorbs engine and driveline torque, endures shock loading,
and accommodates twisting on uneven road surfaces. I think the DeLorean
frame was probably the best of all possible options at the time -- rigid
enough and yet flexible enough to perform adequately, not heavier than it
needed to be, and self-sacrificial in the event of an accident.
