Federal emission regulations, and local emissions testing are not the the same thing. On top of that, most states have NO testing for diesel vehicles, California being one of them. Those that do are usually limited to just opacity tests. Testing is based on impact, meaning population density. The reason not all cities in my county are subject to testing.
All on road diesel engines are subject to the new regs. DPFs and NOx catalyst. The big 3 are selling diesel powered pickups that meet the new standards as well as the tractor (big rig, not cornfield) manufacturers. Economics is the biggest factor in why the Euros can't/won't meet the standards. Increased cost/small market. Higher initial cost, coupled with high diesel prices makes a hard sell. Plus, the regs get even tighter in 2010. California has already adopted the 2010 regs, further limiting the current market.
