New Cadillac CT6 will have a CADILLAC V8
AWD
A twin turbo hot-side, Cadillac Exclusive engine. Comes in the two different horsepower versions, although it seems like there isn't a great spread between the two. It's paired to the 10spd auto, so turbo lag/dropoff between shifts should be minimal, if any.
Forged aluminum rods? (another article from Autoweek said forged steel con rods, so I don't know)

How do they manage the heat from such a configuration - yes, I'm ignorant.
Some specs:
4.2-liter preliminary specs:

GMauthority has some more drivetrain details, although I think the wording is somewhat vague or proofing needed?

20psi is 20psi...lol. Doesn't matter how many turbo's there are. Silly journalists.

I would guess it would still be mostly the same if both turbo's fed one intake manifold. Its the same amount of air going into the same amount of engine
