Right now, excepting trucks, I think there are only three vehicles available in the US with diesel engines:
* Mercedes E-Class
* BMW 3 Series
* VW Jetta
Two of the above are high-priced luxury cars in the $35k-$50k price range.
That leaves VW as the only automaker selling a reasonably priced diesel-powered passenger car in the US.
Meanwhile, in Europe, about half the passenger cars on the road are diesels... everything from micro-compacts to big luxury sedans.
Are they more "green" than we? Or are our laws just more stupid and inflexible?
