You can blame CARB and the push to ban diesels. Fuel supplies are limited in CARB states thus driving up the cost for fuel HOWEVER owners of diesel have long ago realized that we travel nearly twice as far per gallon thus fuel is still significantly cheaper than gasoline when viewed per mile traveled.
In the vast majority of the US diesel is always cheaper than regular unleaded. Only until you get out west does the price go up, again mostly to the cost of transport and lower sales volumes.
A few states are pushing for different tax laws to compensate for higher fuel economy vehicles which reduce the states tax revenues. There is talk of taxing by the mile verses per gallon, however the arguement can be made that higher fuel economy vehicles cause less wear and tear so the current system compensates already for vehicle size and damage per mile.
This fall MB is bringing over the R class and M class with the CDI and increasing power output to 220hp and 400ft-lbs of torque. Fuel economy will reflect the increase in weight being moved but in both case it will remain above 30mpg for either of the vehicles. The E class will get the V6 CDI labeled BLUETEC which it appears the EPA is signing off on for sale in the US for all 50 states.
The other factor with fuel prices in the slow introduction of ULSD, the trucking industry is crying over this but in the long run it will allow us to get a much wider range of diesel options. What is not being told to the industry is that ULSD will allow tuning that increases fuel economy further, the trucking associations are peddaling fears that truckers are going to lose economy due to the new 15ppm sulfur fuel when in fact the fuel economy will go up. Cost for refining fuel from the current 500ppm standard to 15ppm is around $.05 per gallon. The other issue is cross contamination in the supply chain from high sulfur fuels like gasoline and Jet fuels as well as off-road diesel which is dropping to 500ppm standards this year.
All one has to do is drive the Audi V8 Twin turbo diesels in teh A8 or a Bimmer to know that the top of the line cars in Germany are powered by Dr. Diesels unrivaled motor of efficiency.
