OK!
I'm a F1 fan for exactly 20 years (my first GP on TV was Great Britain 1983), and I think I saw many strange ideas and projects, but surely this one is the very strangest!
From Autosprint 25/1993 - June 1993 - page 36-39:
Do you want an Indycar Version? Here it is!
There is also an interview to Scalabroni, where he explains in few words why such a strange idea.
It is in Italian, so I try to translate the main ideas. I'm sorry for my poor technical English, I think it's better for you my strange phrases rather than the original in Italian!
First of all, according to F.1 rules (in 1993) a F.1 must have at least two steering wheels and it can't be a 4 wheels drive. There isn't any rules about three wheels drive, like this one (Note that at end of 1993 also 4 wheels steering were forbidden but I don't know exactly if such a system now would be allowed anymore).
Such a car has a minor frontal section because there are no big wheels (back tyres were 18" in 1993, IIRC); lateral tyres on this project should have been standard front tyres on standard F.1. For this reason it is 25% more efficent: it use a 10% for a bigger back wing and a 15% for improving speed.
There are two viscous differentials; standard transmission and a cardanic transmission for the back steering wheel. Three wheels drive means more grip. Ideal engine would be a V8 (remember that in 1993 there were V8, V10 and V12 and all of them were quite god in F.1).
Front suspension is quite similar to motorbike or could be derived from aircraft wheels.
If this car could have active suspension (allowed in 1993), in could lift interior wheel in bends.
So, what about it?
Ciao,
