A kammback that follows the template will have limited benefit, if any, on a sedan. Kammbacks work better on boxy hatchbacks where their rear aero is worse. Even a fill boattail on a sedan may not have magical gains in relation to the work invested in designing one. A tail extension is simpler and does improve economy by giving the detached air down the rear of the car something to attach to. Try tuft testing the rear of your car to see where airflow is attached and where it isn't to give you an idea of what you have to work with.

You're still running your tail extension though, right?
