Interesting that Detroit is sold out. Where are they all going?
Maybe they just aren't making them as fast since Prevost switched to Volvo engines, and just about all the new MCI's I've seen have a bright red Cummins ISX showing just under the rear bumper.
Just about all the new high end trucks I know of have a red engine in them as well
I'm not sure what happened to Detroit? But I am guessing it is the same thing as Caterpillar. Caterpillar stopped building over the road Diesels because of the new emissions regulations. They figured that they had a good enough market in the off road vehicles and equiptment, and they didn't want to get a bad name over the emissions problems. I know first hand that the auto industry has many problems with their Diesels. I can only imagine how many trucks and autos in the colder climates are going to have problems with the urea injected Diesels.
