2020 6.7 Power Stroke w/Steel Pistons
Here's a video from Mr Truck. He missed it, but the new Power Stroke will have Mahle Steel pistons. This should make this engine platform good for an easy 1 million miles. Link

With the slower rpm of the diesel engines steel pistons are definitely possible. Trying to run steel pistons in a high rpm engine may cause UFO's as parts try to leave the engine bay. :)
