I really like the Edge - had one as a rental car once & have decided on this as my next vehicle. I haven't seen anything concrete yet on the 2011 Edge & Ecoboost. I am excited about the Ecoboost engine & would wait until next year for one. If not, will probably find a used 08 or 09.

 

I remember there being some discussion about that engine coming out in the Edge, but I do not remember seeing anything definative.

 

Old thread but bears updating, 2011 appears to be the year of ecoboost multiplatform launch.

I read recently that the edge will get the 2.0 4cylinder ecoboost in 2011
