What could F1 be like if there were no rules at all to restrict the speed on the cars? Would we see cars with 6.0+ litre extremely forced aspirated engines outputting something 5000+ HP? What about an extended superlight body to cover the wheels on the car to reduce drag? For tires slicks are obviously better than those rilled tires they use nowadays. Some fun ideas: what about stuff such as dynamic, computer-controlled suspension - giving optimum ground effect at all times? Dynamic but driver-operated spoilers - so you could adjust the spoiler angle yourself, to go from no downforce at all on the straights, to extreme, maximum downforce when cornering. This would also allow the wings to be used as an effective air-brake by setting the angle to more than maximum effective angle of attack for downforce. How about the same principle on camber and toe? Wouldn't a driver-operated dynamic asymmetrical camber greatly improve grip while cornering? The car's four wheels would "lean" into a corner - somewhat in the same manner a bike does while cornering, and when the opposite corner comes you make the wheels not only turn, but also lean (camber +/-) the other way? Is any of this feasible in terms of what technology - not rules, allow? Personally i think F1 cars go fast enough, there sould be some safety in F1, there has been so many horrible crashes in racing history (although there are some other things they could change to make the sport more interesting like it was before, but that is the topic of a different thread). However i find it fun to think about how fast the "ultimate" race car could have been with modern technology, because F1 is not modern racing technology at its best is it? It is modern racing technology at its best under the rules and restrictions that F1 provides and demands.
