Initially, the idea was envisaged by Ferruccio Covini in '74 and made stipulation for 10 inches front wheels for reason that there were no low profile tires back then.
The venture was abandoned in favor of the Soleado model, thought to be more significant, and remained inactive until the 80s when hydro-pneumatic suspension for the four front wheels where designed to maximize weight sharing under different loading situations.
High cost of development and other unforeseen events obliged the venture to be postponed once more. Its utilization of current ABS technologies and airbags in the 90s pointed it toward new research into dynamic and passive safety.
This aspect motivated support from companies for its continual development. Six wheels because in case of a flat front tire, vehicle control is ensured by the wheel next to it.
Four disc brakes at the front, even though a smaller single space, makes sure that there is a greater braking surface; of course, this means reduction in the chances of overheating and a higher brake effort and a low risk of aquaplaning, provided by the two foremost wheels, which get rid of water for the ones behind them, guaranteeing an enhanced road-hugging comfort.
The consequence is more evenly distributed reaction forces in the suspension; in case of a pothole, the reaction is divided between the four front wheels and the shudder in the chassis is greatly restricted. The reduced unsprung weight in the wheels enhances the hold also.
Directional stability is better: a change of angle due to slack in the steering mechanism, in such structures as silentblocks, is balanced by the second set of wheels. Two extra springs and dampers offer superior vehicle handling.
