The biggest news is the steel pistons that will handle some serious cylinder pressures along with a stronger more efficient turbo.

This will be a serious medium duty engine.

Steel pistons are nice and stronger IF they are the same size as the older pistons. If not, then they are just using it to to save weight. That is just like high strength steel frames. Stronger metals can be used to reduce the mass which reduces weight, but it doesn't necessarily meet stringer over all. It just means that you can use less of the stronger metal to achieve the same strength of using more of a lesser metal.

The Mahle forged steel pistons are stronger than cast or forged aluminum pistons and have many advantages over aluminum. A couple of strengths is piston cracks and erosion is a thing of the past.

A copy/paste from this link:
Unfortunately, piston selection is one area where light-duty diesel engines lack what heavy-industry diesels have had for years: steel pistons. Aftermarket, forged-aluminum pistons surfaced a few years ago but lacked the durability of OE cast-aluminum units. Fortunately for us, Mahle Motorsports came up with the Monotherm: a forged-steel, extreme-duty piston. And while they come at a price, they can be used for any purpose and in any application, from daily drivers to tow rigs to competition-only vehicles. The Monotherm piston is as much as 100 grams lighter (in certain applications) than comparable cast-aluminum units thanks to the removal of unneeded material. It’s also much stronger thanks to its high-grade, chromoly-steel construction. Designed to withstand extreme, in-cylinder heat and equipped with oil cooling galleys to reduce thermal stress makes them the best of both worlds. This piston can be part of your million-mile puzzle or your 1,000hp competition killer.
