I haveta say that since urea injection became a requirement on tractor trailers/buses, I love that the air doesn't smell like diesel exhaust on highways or at bus stops.The diesel in the Aussie Cruze meets Euro IV emission standard and has a self cleaning Particulate filter that is claimed to last the life of the car. We have used some kind of emission equipment on our cars since the mid sixties, every new model gets a little more. This is in a country as big as the main part of the US and yet has a population of only 23 million. Apart from the cities it seems a bit over the top to me?
I remember riding school buses - the old Chevy 350 diesels that coughed out huge clouds of black (and sometimes blue) smoke - where the diesel smell used to make me sick going out to the parking lot where they were all idling. I ride a commuter bus every morning, and aside from the intense vibration and noise from the back of it, there is no smell whatsoever.
