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.

Steel pistons have advantages over cast aluminum but saving weight is not one of them. Steel pistons are stronger, they offer longer lasting more stable ring grooves, they expand with heat similar to the compacted graphite engine block, they allow for oil galleries to be incorporated into their design for better cooling.
