I have to wonder about autos with higher EPA ratings...does it translate to reality or is it because the PCMs are "gaming" the drive cycle? I still believe that it would be easier to get better mileage through altered driving habits out of a stick than a manual.
Exactly right. The bosses bosses boss comes down to engineering and declares "mileage must improve, I don't care how you do it". Now we know EXACTLY what the EPA mileage cycle will consist of. EXACTLY. We could build an ECU that recognized the EPA test if we wanted to, and hypermile the engine when we detect an EPA test is being run. Piece of cake.
I wonder if the emissions test are done with the EPA drive cycle. If not, lean burn and to hades with the NOX here we come
