In other words, there are returns to be had but they will be minimal (as in, hard to see at the pump) on most modern passenger cars?

Just for clarification, the Cd 0.12 is hypothetical?, based on the research
if Chevy had boattailed the 2013 Malibu Eco or did they test a boattail on that car?
So the Malibu would go from Cd 0.29 to Cd 0.12 if they only added a full boattail that follows the template??? That means overall drag would be roughly 1/3 of what the production rear end allows. If this is the case, I can see why it is worthwhile to pursue drag reduction at the back of the vehicle.
