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) http://autoweek.com/article/technolo...lac-has-new-v8 How do they manage the heat from such a configuration - yes, I'm ignorant. Some specs: 4.2-liter preliminary specs:
http://www.autonews.com/article/2018...sive-engine-v8 GMauthority has some more drivetrain details, although I think the wording is somewhat vague or proofing needed? http://gmauthority.com/blog/2018/03/...hiseled-looks/ |

Didn't they have a massacre there?

Glad to see GM is finally stepping into more modern times. Can't wait to see how this engine holds up.

Love this quote from R & T "The turbos will be running 20 lbs of boost apiece, shoving air into cylinders with a 9.8:1 compression ratio"
Uuuuh??, so 40 pounds of boost, LOL!!!!!!!!!!!!!!!! |
20psi is 20psi...lol. Doesn't matter how many turbo's there are. Silly journalists.
|
That torque number looks nice.

If there are two totally separate intake tracts (including into each head with two separate throttle bodies), then maybe it's not as bad as I first thought. |

The more I thought about it, maybe they phrased it that way since the turbos are in the "V" of the engine.

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 :)
didn't even know that what they wrote sounds weird LOL!!! |
Ford pickups are like this, two tiny turbos.

They're not in the valley though.

How long do the modern, (highest quality - I assume in this case) oem gas-engine turbos last?
