That makes no sense whatsoever. You obviously don't know what you're talking about. In 2005 in the US, TDI engines were in 15% of Jettas sold. In Canada the figure was 50%. We love diesels up here, yet I believe we get somewhat colder winters than you do.
Tier II is not alone to be blamed on reduced diesel efficiency in recent years. The later TD engines ran at 22:1 compression, than the first TDIs were at 19.5:1 and the new 2.0 16v CR engine runs at 16.5:1. That's the tradeof to go after an higher hp per liter figure. The whole bsfc map is being pushed higher up the rpm range with every generation. That have a cost on fuel economy.
