MPG has proven to not be an advantage of the Ecoboost engines. Test after test, it gets no better MPG than engines it competes with (Hemi, GM 5.3/6.0). A V8 EB would be WAY too thirsty.

True. When towing and under boost it has the same power and mileage as the big V8s.

But when not towing and not driven by a lead foot, you can do much better. My long-term average is 19.6mpgUS, not towing. EPA hwy is higher.

As they say, it's Eco or Boost. Not both.

Now whether a big V8 with cylinder de-activation is as good or better than the 3.5L EcoB is another question for another thread.

Yep. My 3.5 EB gets approximately 10% better fuel economy than the 5.3 in my Suburban under most unloaded circumstances.

And the EB kills the 5.3 when towing, although it does get about the same mpg doing it. Of course, I'm going faster in the EB when towing, so ...

I expect, from numbers I'm seeing, the 2.7 would probably best my 5.3 by 20-30% in unloaded economy, and would still out-tow the 5.3.

People like to jump all over the EB for its lack of "eco," as though it should be competing w/ a Honda Civic as far as economy goes. But 10% better fuel economy and lots more power than its direct competitor is literally a win-win scenario.
