Gauss:

I would be surprised if the new RS were getting 550 hp. More like 25 or 30 hp increment. I can see 550 hp in the last special edition RS, like a 991 version of the 997 4.0 RS

unless of course it's a hybrid turbo/NA, which I highly doubt, then I could see 550 hp.

The conclusion of the above article is 4.0 l ( not 4.2 ) with max 430 HP ...
