The v6 and v8 get almost identical mpg

Don't forget that when you're talking about a 16 MPG vehicle, 1 MPG is a significant difference in volume/cost of fuel used. See post #5.

figure in the v6 gets driven harder to perform the same, its a tie.

I see this repeated often, and I'm skeptical. Sounds like a truck drivers urban myth /slash rationalization.
- The EPA test cycles run the engines at the
same rates of acceleration and
same speeds (ie. "perform the same"), and the smaller displacement engines win out over the bigger ones.
- For "real world" results (if you assume the sample size is big enough and representative), check the "Your MPG" numbers on the
www.fueleconomy.gov site and I bet you'll find that smaller displacement engines also get better MPG as reported by real drivers
Pre-emptive point: anecdotal stories (lacking solid methodology) don't count!
