I've seen a lot of reports of GM bringing the diesel Cruze to the US. This opens up the obvious question: Would GM ever consider using the diesel engine as the range extender in the Volt?
After a little thought I suspect the answer is no.
1) Increased cost of the diesel option
2) May not be as well suited for start/stop applications like the Volt.
3) Increased NVH
4) More power and torque than needed for the Volt (about 100 hp and 100 lb-ft more than the current 1.4 engine)
Hmmm, now I'm thinking this would be a nice basis for an EREV truck powertrain.
