Getting Good Gas Mileage Is Hard; Will Tinier Engines Really Help?

I noticed, Anthony posted the link to the article on a gaming forum I moderate. I believe he's joined here under the name "RunningStrong".

I think the premise is good, but needs more research. Anthony knocked it together based on a conversation we were having on that forum about the Ford EcoBoosts.

In part, I agree... sometimes an engine is too small for the work desired. When I did the EcoBoost Explorer, fuel economy in traffic was just as bad as the V6. Whatever the size of the engine, accelerating two tons of metal (however gently) up to speed requires a lot of gas. But I partly disagree, because from my driving, I saw the potential for extra highway MPGs simply by staying out of the boost.

Unfortunately, since part of the premise of the EcoBoost is that you don't give up power for economy, these new engines are tuned to produce lots of boost very early, so most people don't see any benefits.
