Thanks for the update.
I've now seen comments on several sites from Fiesta 1.0t owners saying they can easily beat EPA with these cars. (Of course the cynic in me says this may also be Ford running a covert social media campaign to try to reverse damage from their earlier MPG ratings overstatements!
)
As for the question of active grille shutters on a turbo, GM has them on the turbo Cruze ECO...
Sounds like they're a fun car. I hope Ford sells lots so they're available on the used market in a few years. I'd love to try one.
