GM just cant wean themselves from the BS.

According to GM’s aerodynamics engineer Nina Tortosa, the old method of testing yielded .19, but with current testing methodology it would equate to .21.

So they didn't actually test it again, just assigned it a number to make the volt look better.
GM's current testing methodology: Utter garbage.
Put the widest, non stock rims and tires you can find on the competition but leave yours stock.
What kind of methodology is that?!!1!. Did they also leave the windows open on the Prius? FERCHRISSAKE!
GM is still full of CRAP!
Wheels account for around 30% of the drag in vehicle design so this "methodology" could easily have produced the few points they needed to come up with their preferred result.
