Ok, last post on this topic.
Yes, almost all production cars generate lift. What they don’t do is generate the 1000’s of pounds of lift required to get them off the ground at 70mph, even with an 80mph wing gust. That’s 150mph generating 3000lbs of lift. Even if it was just the front of the car, that’s still 1000’s of pounds of lift to get it off the ground. Airplane engineers dream about getting this kind of lift to speed ratios and they’re putting wings DESIGNED TO LIFT on their planes.
A great example, a Mooney Ovation3 (a nice medium size private PLANE) has a max gross weight of about 3300 lbs. It needs almost 100mph to take off. But somehow your car, without wings, can fly with just 50 mph more speed.
