Yup it is the Iveco Division of Fiat supplies engines to the Case/New Holland division of Fiat for some of the tractors. And they are excellent engines.
I used to have one of the largest fleets of Iveco trucks in the US (the brand is no longer imported to the US). The trucks used suspensions that didn't hold up very well, but the engines were bulletproof we easily got 200,000 to 300,000 miles out of the engines and probably could have gotten a lot more if the rest of the vehicle would have held up. In fairness to the brand, we pushed the trucks to their maximum weight capacities almost daily.
