Would it be worth it to pursue diesel engine technology for passenger vehicles in the U.S. in order to increase fuel economy, albeit at the expense of higher NOx emissions?

    Yes. In the US the fuel economy is very important as people travel much larger distances than for example Europeans. This means that small amounts of personal savings can add up to a real big difference. While people may still be thinking that diesel engines are “dirty” they have come a long way and that statement no longer is valid. Just recently the greenest car of 2010 was the Audi A3 TDI (which is a diesel engine). Furthermore German engineers developed a truck engine that meets the Euro 5 emission standards.
