The Obama era fleet efficiency standards don't bode well when looking at big heavy trucks. If they could put their efforts primarily behind one car, they could come out ahead on profitability. Doing so would greatly reduce the supply chain complexity, part variety (though shared parts across models has gotten much better in the last decade), inventory costs, etc. This would help service shops, suppliers, and their logistics. It will be interesting to see how this develops. Disclosure: I work for a Tier 1 supplier.
