The GT-40 was not designed in a wind tunnel. When it finally made it to a wind tunnel, they found that the complex "airflow managment systems" i.e. scoops and ductwork, consumed more than 100 horsepower. The drag coefficient of 0.43 would not suprize me.

Based on Ford's claimed top speed of 195 mph for their new Ford GT, the drag coefficient works out to be around 0.38.

Due to improvements in design, the Superformance Coupe will prove to be more aerodynamic than the the very sleek Daytona Coupe, which is substantially better than the Ford GT. The Superformance Coupe has about the same frontal area as the Ford GT and about the same horsepower. With the lower drag coefficient, it should be at least 10 mph faster. And that would be 205+ mph.

But this is just bench racing - words and math. Someday somebody will prove it and I hope they report it here.
