From the customer perspective, it's a shame US diesel fuel is now so expensive. T2B5 diesel technology sharply reduces CO2 emissions while still meeting even California emissions, but the advantage in fuel cost per mile is getting smaller - unlike the up-front premium over a gasoline engine.

For large sedans, minivans, SUVs and pick-ups, T2B5 diesel still deserves consideration, even in the US. After all, it's been a cold winter and (too) many homeowners on the East Coast still rely on heating oil, which is really just a less refined grade of diesel.

Note that a gallon of diesel contains 12-15% more energy than a gallon of gasoline. Historically, US diesel fuel has been cheaper than gasoline, if not per gallon then at least per unit of energy contained. Only time will tell if the introduction of ULSD has permanently altered the price relationship.

If I remember correctly, heating oil is diesel fuel. The only difference being that it is not taxed for road use and as such contains a red dye that stains the insides of the fuel tank so that owners that use the fuel in their cars can be caught and fined.
