Its political, it was the EPA making the announcement on the evening last Friday the 22nd while everybody was getting ready for Christmas, this is another case of incoherent people who believe in unicorns making impossible mandates to the point where OEM's have to develop certain tactics in attempt to defeat government stupidity, it happened to VW, and then they moved to the Ecodiesel where the firmware update turned the engine into a slug, it wont be long till they start on gassers, looks more like shutting down companies by fining them out of business, the winner here would be China.
