*Whatever* angle of attack or airfoil design doesn't matter; the above holds true... unless you want to get funky and talk about undesireable situations like stalls and whatnot.
Keep in mind that "lift" can be in an up or down vector, depending on. For cars we tend to want "down".

I beg to differ... wing efficiency has a great deal to do with the relationship between lift and drag. I am not saying that you can avoid drag when producing lift, but that some wings are able to produce far more lift for a given amount of drag than others.
