yup
Basic interpretation is closed gate makes a pocket of air in the bed. Higher speed air then flows over the cab and this pocket in the air. Dropping the gate gets rid of the pocket and air that would normally have flowed over the top now get pulled down hard behind cab and exits the rear at deck level, thus more drag with gate down.

Another result of sloped glass is cleaner air over the spoiler and more downforce. Isnt air cool <img src="/forums/images/graemlins/smile.gif" alt="" />


That's what the original argument was, but the study by the ME student says otherwise. He says it's better with the tailgate down, rather than the tailgate up.

If you have to ask about a SAS, you're not ready for it.
