Also contributing to the overall

it has therefore been possible
to improve the deformation
characteristics of the passenger
cell even further.
Since 1985, all Porsche doors
have had a 'crash barrier' made
of ultra high-strength steel built
into them – otherwise known as
side impact protection. The
