Look back at some old footage and you will find lots of cup cars with a spoiler and open roof flaps flying when the get turned at high speed. The only lift that wing provides is once it’s to late and the air flow is perpendicular to the surface of the wing. If you look at the footage of this weeks wreck that force was not even enough to pull the trunk open let alone lift a 3400 lb car. More then one factor is at play here for sure but IMHO the air being stuffed under the back of the car is the major cause. Wouldn’t you love to see the data from NASCAR’s many trips to the wind tunnel trying to solve this issue. Would definately be some interesting reading. Have a good one.

JA — the rear bumpers are lower than the old car so the air going underneath is less. They lowered it to meet the front of the car better when drafting. NASCAR says the wing is not an issue, but I seriously doubt that. The old car would get up there as well, but the roof flaps worked. Something is going on with the design of the rear of the car and that includes the wing blocking air to the roof flaps. But we will see what happens when the spoiler goes back on.

The cars fly because when it gets tuned around all that air gets stuffed under the rear of the car (The huge opening under the rear bumper) and away it goes. A wing designed to make downforce Does Not make lift when air goes over it backwards. Even NASCAR said that the wing is not the problem. If there was a way for the air pressure under the car to be vented when it is going backwards (trunk lid flaps of some sort) the cars would be a lot less likely to fly. Have a good one.

in my opinion the spoiler is useless…
