Good morning!

Sorry to reanimate an old thread, but years ago we had a nice discussion about all of this. That thread got lost, but the frontal area is 16.6 sqft, the Cd of drag is about 0.6.

We couldn't determine the real value because it's a part of total drag and it's changing when the car lifts at speed (as does the frontal area).

In essence, Cd (coefficient of drag) is a variable, most likely from 0.55 to 0.65 for a Cobra.

To go 180mph you need 430Hp, with a hardtop and open windows (that's how we tested in 1995). Side note: If you reduce your windshield size to a single seater you need only about 320Hp to drive 180mph. That should improve your 1/4-mile time too.
