Shady and disgusting? I've no idea where you draw that conclusion from.
Anyhow, the 6 wheeled technology was never gonna take off. I know that a few teams tested them, Ferrari even went the tandem route, but the only 6 wheeler to be somewhat competitive and win a race was the '76 Tyrrell P34. The cars and concept were not 'too good'. Someone mentioned 4wd earlier. In 1969 several teams experimented with 4wd, McLaren, Lotus, Matra and Cosworth, but as the teams began to understand the complexities of aero downforce and grip (which then was in its infancy) they began to understand that 4wd offered zero advantages. The cars were overweight and piggishly slow. I know that Chapman perservered, much to the consternation of his drivers, but the whole concept was a lame duck.
Not actually correct. The FW07D and FW08B (as Williams actually built two 6 wheel prototypes) both set
very competitive times in testing - the FW08B in particular.
As for 4WD not working out - not actually
entirely accurate either. At Indy the system proved to be VERY quick - so much so it was banned along with turbines (albeit before it actually won because of reliability issues) - but the constant radius corners at INdy suited the configuration more than road courses and the extra weight wasn't really an issue since the high speeds were consistent. In F1 Dave Walker was well within a shout of a win in F1 in Zandvort in 1971 in the Lotus 56B too - but it was raining which was always going to play to the 4WD's strengths. Too bad he binned it after 5 laps (rising from 22nd to 10th in that time and being by far the quickest on track). Jochen Rindt came second in a Lotus 63 at the Oulton Park Gold Cup in 1969, too - but that car WAS a shed and only worked with practically all the power going to the back...
