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.
