For the supercar market you need high top speeds to brag about
and some downforce/handling to be able to get in one piece to the reunion to brag. Also for not to be ridiculed with slow lap times (Top Gear?).
A glorified solar cell racer looking car will not make it to this top market, no matter its top speed.
Looks like the story began with the Porsche 959 the first no-lift supercar, a huge improvement over the Ferrari 288 lift.
After that the Ferrari F40 emphasized downforce. This fantastic handling made it an all time favorite.
Bugatti preferred top speed over downforce with its EB110.
The top speed vs downforce compromise was seen with the Jaguar XJ220. They made it both the worlds fastest car with venturi downforce tunnels but with a ridiculous car length and front and rear overhangs. Maybe they had to do it to compensate for the production V-6 over the concept V-12.
I remember the 90s Lamborghini Diablo and how it surpassed the 200 mph mark but without the flashy and badly needed for handling rear spoiler.
After that McLaren F1 narrower width and no fixed wing reduced Cd to 0.32, while diffuser created some downforce. As far as I know this was the first supercar to use active aerodynamics. In its high-downforce mode Cd went up to 0.39 by rising its rear spoiler and turning on some airflow redirecting fans.
Now the Bugatti Veyron used bhp, and low drag to beat top speed records. They had to use variable ride height and a retracting rear wing to reduce aerodynamic drag worsened by its 10 radiators. Some say they used 4wd only to counter relatively poor handling because of its weight. Gordon Murray has repeatedly bashed it.
