I don't buy that those are actually clean. EU has always had majority high-MPG non-diesel cars that you also don't see here as often, simply because gas is cheap in the US. People complain that it's expensive but then 2/3 times go buy a truck or SUV anyway.

How much of the new car market is represented by the average person though? If 70% of the population wants fuel economy but only 10% of the population can afford new cars it is easy to see how the wealthier new car buyers can shape what cars are even available to the average person. Buying a user car in the US gives limited offers for super and turbo charged vehicles, and many turbo cars will want turbo maintence when they hit the used market with lower availability of turbo experienced mechanics.

That's a good point, but it looks like the top-selling used cars are trucks and SUVs too. It's possible on the face of it that this is just because they retain less value than efficient cars and buyers are weighing that vs the cost of gas, but doesn't seem like it from the pricing I've seen.

Having run a ram ecodiesel inside a garage I believe it.
