I guess it depends on the definition of "low drag."

My $20K Mazda3 has a Cd of 0.26, if you can believe the literature. I'm sure Mazda worked hard to achieve that aerodynamic value, but they could have done better by making it look like the model in Post 36.

However, I'm sure it would have cost more to achieve such a shape, and I'm also sure I wouldn't have bought it.
As of December, 1986, Hucho published that Cd 0.09- 0.07 was technically feasible. This would constitute the lower limit for total drag.
