I agree with both post above (Xpensive & autogyro).
One reason, that we see less inovation is the highly regulated nature of F1 (now for cost reasons), which is wrong IMHO.
One of the most stupid rules is the minimum weight limit, and the ban on different transmission systems (CVT).
most of the systems, Xpensive mentioned above where pioneered in a era of free competition. radial vs. bias ply tire, n/a vs. turbo engine etc.
If we want to see more of this, we should go back to fair and open competition, so that the best system wins.
Not enforcing some artificially limits, like KERS capacity etc.
It will be difficult to have both development of new technologies and cheap racing/low cost of competition at the same time.
the solutions produced in F1 (or any other form of racing) will allways be a functions of the rules governing the sport. So let´s not blame the engineers,aerodynmists for the solution they (are forced) to produce.
F1 is per se, not best placed to be road car relevant, as open wheels are not really the norm in todays cars, but do we want to use that argument, to stop F1 and only focus on sports,touring and GT-car racing?
Aerodynamic as such is quite relevant to road car engineering, and ground effect aero is used on high end sports cars these days - so not all bad here I guess:
Trend of the aerodynamic downforce coefficient of Ferrari GT models recorded over the last 20 years. Since the 355, which was the first downforcing car, the downforce of all following models has been continuously increased. On the V8 rear engine cylinder up to 8 times more than the 355.
