Round off error in published figures?
for example...
Sedan has a cD of .305
Wagon has a cD of .314
So published figure is .31, for both - despite the 9 point difference?
That still doesn't explain EPA figures - I would hope they use at least three decimal places... And there's no excuse for bigger FA

Since they can't test every vehicle, they test similar engine/transmission combos of similar models and make an "Estimate" -- despite the added weight and different aero of the wagon.

Or that makes sense
