Formula 1 is nothing if not dynamic. Every now and again, the Powers that Be decide to shake up the rules in a big way. This is inevitably followed by a large spike in exploration to see who can best leverage any advantage to be found in the new sporting regulations. From those bigger chunk explorations, a leading approach arises, which drives others to replicate, refine, and improve upon the original premise. We know the successes, but we can also see the historical trail of tried and abandoned innovations. Lotus attempted four wheel drive to find better grip when power increased, but aerodynamics won out. Brabham tried to bring Jim Hall's Chaparral vacuum car technology to Formula One, but ultimately it was nullified. And in 1976 Tyrrell debuted their well known six wheel car.
