Thinking of getting a fusion sport

I have spent the past few hours researching the sports only to end up more confused, so I have a few questions

  1. Is the 2.7 ecoboost the most powerful engine they put in these? It looks like they only put them in 17-19 models, but i also see other engine options. I'm looking at the one with 325hp and 380ftlb

  2. What are the common issues these cars have? I saw stuff about leaking oil pans

  3. How easy are the 2.7l to work on? I know replacing the turbos in the taurus shos can be a nightmare, same with the water pumps.

  4. Is the awd system basically the same as the taurus shos? Are they easy to drain and fill the fluid?

Thanks for any help!
