It's not about 'consumer choice', it's all about emissions. Until last year the diesel fuel sold in the USA was high sulfer and they couldn't meet emissions guidelines for diesel cars. They changed the fuel last year to low sulfer, and they could bring in diesel motors to meet the current standards, but the bar is being raised again in 2009-2010. Emissions standards are getting so tough that even Caterpillar has announced that it is ceasing production of on-road diesel engines in the US market next year. Even the big truck guidelines are getting too tight to be met. So Ford isn't going to bring that car over here for 1 or possibly 2 years because then diesels won't meet guidelines again. It has nothing to do with what the consumer wants, it has everything to do with government regulations.
Could it be that the diesel regs have been getting so strict because it is easier to pass a bill with tighter diesel emission regs than it is to pass a higher CAFE or tougher gasoline regs?Might it also be that the formulas used in the US regs distort the actual *total* pollution when comparing diesels to gasoline engines?
Diesel isn't a "zip-around" engine. Diesel works good for those who are steady drivers and plan their trips (tactics) to avoid jack rabbit starts. Diesel is a working engine and, because of its heft, can take the abuse of using it for a brake and providing long uninterrupted periods of travel.
When I was deployed to Iraq, we had several 4-door Ford Rangers with diesels.
I've only owned one diesel road vehicle in my life and it's sitting at the side of the house right now. It's the Chevrolet Kodiak C60 that I used in my sawing business. It as a 16' flat bed and a 3116 Caterpillar Diesel engine that gets 12 mpg whether I am loaded or not. While I might be able to accomplish most of the same things with a one ton truck, I couldn't with a sedan. Yet, most of the people who make the most noise about conservation never consider the use of the vehicle, but only measure the "size" and MPG. I'd be willing to bet that very few of them know anything about a spark plug, the difference in 2 cycle and 4 cycle engines, the carrying capacity of a vehicle relative to the 'load per gallon', nor the driving habits of the operator.
