Per the Ford and Mazda webpages:
3.0L Fusion: 221 hp @ 6250 rpm
3.0L Mazda6: 215 hp @ 6300 rpm

The base engine themselves are practically the same but then you have to put on different intakes and different exhaust systems. These and the calibration will be tuned for different customers and different goals such as fuel/power/emissions.
