I got a question that maybe someone can shed some light on. How come auto companies are so hesitant to release small, high-efficiency, high-torque diesel engines in North America? I can't seem to understand especially when there are so many European vehicles sharing the same chasis that have the latest in diesel technology.

VW tried it, and you know what? They sell everyone. I'm not sure about the US but Jetta TDis are impossible to find and even used ones are selling for nearly as much as new.

Why can't I get a 35mpg, 260lb-ft chevy Equinox?? Why can't I get a 45mpg 200ft-lb HHR? Wouldn't that make sense?

So seriously now, and I know its not just GM, why aren't companies sticking these engines in? Is is EPA, is it regulations/certification costs?

Easy.

U.S. emissions chokes the diesel down, making fuel mileage over competitors not what it should be.

Diesel is much more expensive than gas.

The price of certification for the U.S. is way too high.
