There are just too many vehichles out there now where manufacturers have opted for the turbo 6 over the large V8 because they got better gas mileage to make this much of one oblique statement about one car without any real data provided.
Show me the data for one vehichle where the large V8 makes the same power as the TTV6 and as good or better fuel economy. That's all I'm asking.

If it produced similar mileage in a lighter car, what makes you think it would be different in a slightly heavier one? The gearing insn't going to be that different between a Vette and a Camaro either, so that argument is invalid.
