Actually it seems to me they figured out how to handle the select shift differently in testing so as to get no drop in the EPA rating. Previously the select shift equipped cars got 27/37 and the non SS equipped cars (S and base SE) were 28/38. Now it appears all are rated at 28/38. I would've thought that if it was due to the shutters, and the base SE's also got the shutters that they'd increase to 29/39. But recent SE arrivals at Brandon Ford near me are still at 28/38. So either the base SE's are not being equipped with the acitve shutters now or they're now somehow getting around the select shift penalty they used to get.
