Wanted to get your thoughts on this one. http://usnews.rankingsandreviews.com/cars-trucks/best-cars-blog/2013/07/Ram_1500_EcoDiesel_Promises_Best-in-Class_Fuel_Economy/ "Chrysler Group hasn’t given any specific fuel economy estimates yet, but it expects the Ram 1500 with the EcoDiesel to be more fuel-efficient than any gasoline V6-powered half-ton pickup truck available. The most fuel-efficient non-hybrid full-size pickup truck currently on the market is the Ram 1500 equipped with the 3.6-liter V6 and eight-speed automatic, which is rated at an EPA-estimated 17/25 mpg city/highway. With the diesel engine, Pickuptrucks.com predicts that fuel economy estimates will be about 23 mpg city and less than 30 mpg highway." I say it's about time. I've been waiting for something like this to come around for a while. Personally I love diesels but have no legitimate justification for the big V8 because I don't haul heavy loads. This would be right up my alley. I also don't buy new vehicles so would have to wait a year to get this truck but it gives me time to get real world reliability statistics and driving impressions before getting one. The master plan is to build a shop and have 2 diesels, one for the wife and myself, and supplement fuel with bio diesel from the shop. Anyone know if the Mercedes or Audi diesel engines will take bio diesel as an acceptable fuel?
