I see that there is a possibility that it will become an optional engine in the US, and that certainly is exciting news. However, they would presumably have to clean the engine up extensively in order for it to pass our extremely stupid diesel emissions tests for 2007.
But, GM has said they have three diesel engines on the way, and DCX is preparing an all-out attack with the BluTec not only in their Mercedes line, but in their Chrysler, Dodge and Jeep models.
Diesel power is indeed the future, but unfortunately here in the US, the majority of the public still needs to be convinced that diesel power is not only more efficent than hybrid power, but is also cheaper as well.
...Maybe we should force everyone to watch the Top Gear test of the VW Polo or Fox to see how great the fuel economy can be, and maybe we could forget about those silly Prius models.
