"ARTIFICIAL AERODYNAMICS"
 

Manufactures always try to improve aerodynamics for their next cars in order to increase • efficiency • top speed • grip • even less dust in our cars and much more things but some others try to do it more artificial here is a race car which is made from chaparral its named 2j

this car use fans as vaccum to generate massive amounts of downforce in order to have massive grip into higher speeds
and they are more examples like mccurty ev which hit a record and much more even somoene try to increase lift and downforce but i dont have see something for drag and thrust do you know any other expriment write below

'any other'
 

Historically, race teams will scrutinize the 'rulebook' from the sanctioning body, and if some 'technology' is not specifically forbidden, they'll show up like Carrol Shelby, and compete on a 'nastier' basis.
Smokey Yunick was famous for cheating in NASCAR.
Chrysler Corp. cheated year after year in the MOBIL ECONOMY RUN, and later bragged.
At Bonneville, any LSR achieved includes impoundment after the 'victory', with a mandatory engine disassembly and inspection to guarantee things were as 'advertised' by the owner/team. ( I suppose that the Southern California Timing Association has seen every trick in the book!)
Jim Hall's Chevy Chaparral 2J technology was banned the next season.

You might want to take a gander at Ben Bolby's 2012 NISSAN Deltawing, Le Mans entry.

There is a long and varied history, from propellor cars like the 1932 Helicron

With it's annular duct and externalized flow, to the Gordon Murray T.50
It achieves both downforce and thrust with internal ducting.
