I've read that Ford substantially changed the design of the 2.0 EcoBoost for model year 2015 Ford Edge. The new design featured a twin-scroll turbo configuration and the manufacturing moved back to the U.S. I've read some conflicting info online about if this new engine was used in 2015 & newer MKZ's or if the all MKZ's 2.0 use the same design since 2013. I think it would be odd for a manufacturer to produce two different engines of the same displacement and very similar power output. I have the 2016 2.0 AWD and it's been great so far.
