THUNDERA 5pts Of course, another benefit is fuel efficiency. While 15-16 mpg in the Rover is respectable (well, its better than I would've expected) the Touareg can easily achieve 20 mpg in the hills at highway speeds. At the moment, diesel is around 25 cents/gallon cheaper than premium fuel where I live. As you mentioned in the column, us Americans really do need to grasp the concept that is the modern diesel engine. There has been an uptick in models with diesel equipment and advertising new diesel models but we are a long way off. The only way to get it to stick with the American psyche is to keep pounding the knowledge into us. Eventually, it will stick. An increase in diesel refining capacity won't hurt either. I'll make you a deal you work on the former, I'll tackle the latter.
