Test the manufacturer's own claims for FE at the risk of your own $$. It might be fun, and perhaps there is an off chance that it'll work.
The AutoSpeed story does claim a small reduction in drag for the AirTabs. I see that. But 0.006 is not going to produce a 7% gain. A kamm or boattail is going to be better. I just think those are your better proven options. But if you are curious, then experiment. Share your tuft testing here.
On third thought, maybe your Malibu's rear window is close enough to the angle of the Gen 1 Prius that AutoSpeed tested, though the interaction with the trunklid is harsher:
Good luck.
