Well every single manufacturer does somewhat use the same engine through different lines. It's not surprising when you have a nice reliable engine that makes good power its bound to get used somewhere else too. This is usually a sign that they have a great motor.Interesting the MKZ will be sharing the same engines as the ford mustangs. I never knew that. WOw that explains a lot now. I always thought everything on the MKZ was based on the Ford Fusion.
