Re: "Monocoque"

Thank you Bill for those detailed explanations. I think you understand the problem as well as any of us. If you have a later Elan (36 or 45) you may not know what the stiffness of the roadsters were. There is a great deal more fiberglass in many (like the whole body) locations. Would an S1 or S2 body take all of the loads the way they were built, probably not, but as I said before they are probably not that far off. The top skin mold for the body would not have changed a great deal, the under tray mold was probably a lot easier to modify to accept the full length steel back bone frame. I believe that this monocoque would have come off as planned except for the cost (time and lost time for generating income) that Lotus could not afford. They had the talent to do it, just not the paying public that would wait for it. Lotus needed it now in 1962.
I have kind of been taken by this topic, first good topic in a long while that has never been BEATEN to death. I hacked out some other drawings and while very incomplete they give me an idea of what may have been. I didn't spend much time on the back subframe, about 12 lines drawn. I am not sure how this would have developed in respect to the decision to incorporate an independent rear suspension. I guess I mean when was the rear strut type suspension decision made in relation to the monocoque time line . The front pickup points seem to be something that was well along in the design process when the folded steel backbone decision was made and the monocoque concept scrapped. As usual have a look and then a laugh
The front is missing the engine bay cross brace, I have seen them in racing Elans and there seems to be room for it. that makes 4 different sub assemblies just for the front and that seems excessive. Then again I am not a qualified anything, so this is just an idea on paper to see what it looks like.
