The problem is family sedans weigh 4k+ pounds instead of 3k.
Boosted to the hilt small motors add nothing other than complexity and cost. They give manufactures impressive CAFE numbers because they can run them off boost to test, and give people who want power impressive test drives when they get into the boost.
But long term their are no cost of ownership advantages.
Agreed. These complex engines don't seem to provide exceptional MPG, which as we all know, is often the major cost in vehicle operation. For example, the Ford Escape ecoboost achieved 22MPG on a recent 1800 mile driving vacation AND gas was roughly $4 gallon in North CA. Over 150,000 miles, that would be about $27,000 in fuel costs, as much expense as the vehicle itself.
However, I'd be lying if I said I did not love the power it produced! That's worth something.
Consider the use of yesterday's engines under today's regulatory environment. Vehicles would become significantly smaller, as would engines. The ubiquitous "geo-metro" would be the norm. I'm not OK with that.
