Heck ... who knows ... the Astra diesel drive train might just work in a lot of different vehicles.

Have you looked at US diesel prices lately? Virtually all of diesel vehicles improved MPG is eaten up by the price of the fuel. Add in the $3-5K price premium and I fail to see an economic argument for diesel. I won't even talk about the apparently unsolvable small particulate problem (Asthma anyone?) diesels still have.
