2027 7.3L/6.8L?

I am hearing some talk on the GM side that the next round of emissions regulations for gasoline engine are going to result in some big changes. Some of the things talked about are cooled EGR systems and particulate filters, and the rumors are there will be some reduction in output. I am wondering what this will mean for the 7.3L and 6.8L.

Rest assured that emissions controls and regulatory requirements 😢 will become ever more restrictive. This is why I am planning on my 2024 F350 being the last truck I ever buy.

Once you create a new law, it never goes away.

The talk that I'm hearing so far only pertains to engines with gasoline direct injection, which the 7.3/6.8 doesn't have. GDI engines produce a lot of particulate emissions, so they're trying to solve that by throwing diesel-style emissions systems at it.

Eventually I think the 7.3L and 6.8L will get D.I.. The provisions are cast in the heads already.

I thought the cure for DI particulates was to add port injection and divvy up the fueling to avoid that black puff when you floor it that DI gives you....
