Can somebody explain to me how the Lotus Esprit V8 is constructed ? Does it have good structural / torsional stiffness ? I have seen pictures of something that resembles a tubular steel central tunnel structure which supports the suspension and the engine & gearbox, and on top of that goes the fiberglass body , correct ? How does this setup respond in case of accident ? In front accident is there a crumble zone that absorbs impact ? (I read somewhere the spare tire actually is part of the passive safety !!!) On a side accident are the occupants protected ? What about roll over ? I have seen no steel roll over bars... I am thinking about buying a V8 or an S4 and need some input about safety. Lightweight is good, as long as it is not too dangerous !! Thanks !!
