I did not look very hard last time but the front Subi suspension looked like a modified strut to me.... In any case the lower a-arm looks funky and strange to me. The rear with 4-link... in this day and age... Wow! I though only old 'Vettes had that (C4's before I get flamed)
I am joking a little. The suspension design should be OK, especially if properly strengthened and modded...
I will not take back my comment about mild steel tubing. In this day and age saying that for $10k we have to use material out of 19th century is a little discouraging. Why not cast iron sewer pipe !?!
There is not that much tube in the car, let's say 150'. Chrome Moly tubing would be stiffer and lighter (them even aluminum) for same strenth. It is a little harder to weld, but not that much in a factory setting. Also it is a slightly more expensive, let us say $5 per foot, still only $750. At 150' it would represent 100 to 150 lbs weight saving!
Aluminum like RCR is another material. It is alightly more expensive. One does not need extrusions. RCR and Diasio make aluminum space frames.
Based on the fact that Lambo, Ferrari and Alfa 4c use carbon tubs and do not cost as much a s a fighter jet, means we will see readily accessible Carbon tubs and autoclaves in the next 10years. (For small volume manufacturing).
Would you not pay $5k extra for full carbon tub and aluminum front and rear sub-frame. With the amount of fiberglass on the 818, full carbon (thin racing body) would not be that much more, maybe $3k. Now we would be in 650kg territory with 400hp. Just like old Formula Atlantic or F3!!!
Do not take me wrong. I like 818 and have been watching it for a while...
There are so many cars with transverse mid-engine layouts.... Everyone is trying to make one. There is a guy on Honda forum (k20a.org) that built one from scratch and will write a book about it.
We need to move to the next level! 1500lbs or less!!! 400hp or more!!! $20k or less!!!
I think, I just invented a slogan. We should start a club or a forum...!
We should encourage F5 and RCR and others.
It is double wishbone. As for steel frame, if you have a better idea for a $10K kit car let me know, but this car, all in, is supposed to cost under $15K out of pocket to build. That pretty much exludes more exotic materials or methods. Even doubling that price for contingencies, extras and to have it built for you is cheaper than a comparably powerful Elise.
