We should have a diesel yaris!

The problem with the emissions for the diesel is NO (Nitros Oxide). Steps have been taken such as the introduction of Ultra Low Sulfer Diesel. Which is one of the reasons diesel now costs more than gasoline. Dodge and their diesel manufacture Cummins have gone to great lengths to meet the 2010 EPA guidelines. They went from a 5.9L to a 6.7L. The 6.7 rmp's are lower and thus the egt (exahaust gas tempatures) are lower which in turn produces lower NO levels. Ironically for a small torque increase and better emissions the mpg are 2-3 less. I doubt that most diesel car could meet the forth coming epa levels in the US.
