The problem is, people will start having fun with the boost and get poor mileage.
My parents have a 2014 2.0 Ecoboost Escape AWD. My father and I have no problem getting 30-32MPG out of it (way over the EPA rating). But we drive it light and stay out of the boost.
My 2.0NA Focus can get low 40s and it is rated for 34. Wonder what the real world economy would be on this when there is someone driving for efficiency behind the wheel?
I do like the idea of turbocharging smaller engines and putting in tall overdrives. Best of both worlds! My concern is that they may not be reliable in the long run.
Turbos are getting better, especially now that they are no longer oil cooled.
