We’ve heard all about the twin-turbocharged 4.2-liter Blackwing V8 engine that powers the new Cadillac CT6-V sedan, but with deliveries of the vehicle being delayed due to emissions regulations, we have yet to see or hear very many clips of the engine note or exhaust note.
Luckily our sister site Cadillac Society has dug up a video on Instagram of the Blackwing V8 free-revving, allowing us to hear its deep, burbling exhaust note. The clip is unfortunately quite shot and could have better audio quality, but with only a handful of Cadillac CT6-Vs in existence currently, it will have to do for now.
The Blackwing V8 produces 550 horsepower and 640 pound-feet of torque in the Cadillac CT6-V (formerly the CT6 V-Sport), where it is mated to a ten-speed automatic transmission. The dual overhead camshaft V8 utilizes a “hot-V” configuration, which uses a different cylinder head and intake/exhaust layout to integrate the turbochargers at the top of the engine, within the “V.” The close proximity of the twin-scroll turbochargers to the combustion chamber helps to eliminate turbo lag and also gives the engine smaller packaging.
Additional highlights of the Blackwing V8 include:
- Electronic wastegate control
- Twin water-to-air charge coolers
- Twin throttle bodies
- Direct injection
- Dual-independent camshaft phasing
- Active Fuel Management (cylinder deactivation)
- Variable-pressure oiling system
- Stop/start
The twin-turbo 4.2-liter V8 is also sold in a lesser LTA spec, which is offered in the Cadillac CT6 Platinum. This version of the engine is rated at 500 horsepower and 574 pound-feet and is also paired with a 10-speed automatic transmission in the full-size sedan.
Deliveries for the Cadillac CT6-V with the Blackwing V8 engine are expected to shortly following the emissions-related delays, although it’s still not exactly clear when the first customers will receive their vehicles.

Cadillac stooges: Hey everybody, I’ve got a great idea! Let’s develop a new DOHC V8 Twin Turbo to compete with the Germans, and then we’ll cancel production of the lone vehicle that features it. That way we can put four cylinder truck engines in our high performance V sedans!
GM Management: We’ll sign off on it, but you have to make sure virtually no Americans can buy a car with this engine. We don’t want too many of these things on American roads.
Cadillac stooges: DONE!
Well, Cadillac sure makes a lot of questionable decisions. But I did not expect that growl and snarl to come out of the CT6. That engine/exhaust note sounds awesome!
Caddy, please proliferate that engine as much as possible.
I know EV’s are all the all the rage, and most likely the future, but how do you not enjoy the sound of
the “dinosaur” ICE?
BTW- My razor is electric. But if it sounded like that, I would be shaving non-stop… all day!
Cadillac is Dr Jekyll and Mr Hyde as they can’t decide on what type of company to be, even with the new Blackwing V8 they’re still not sure; you’ve got to wonder if you spends tens of millions to develop a new engine, you would then try sticking the new engine in every car in your fleet that is big enough to fit the Blackwing V8 in the engine bay including the Escalade and new XT6 CUV.
CT5 V8 with AWD. Count me in.
Does Mercedes-Benz stick their V12 into everything that will fit it? Please explain why a Cadillac XT6 would need a 500 horsepower 600+ lb ft torque motor when it’s main clientele only care for style, refinement, comfort, technology, luxury, practicality, and good fuel economy? Nobody is tracking or drag-racing a Cadillac XT6, Lexus RX-L, or Acura MDX. You people need to get over yourselves and off of Cadillac’s balls. Everything they develop isn’t for car enthusiasts, they have to satisfy current customers by giving them their third-row XT5, and the market in order to bring in new customers too.
Just curious to know where the 50hp comes from in the V vs. Platinum trim. Is it only boost or additional timing? Or are there bigger camshafts like the SLS & STS had.
It’s a different tune altogether, no additional/different hardware.
Far to much cheap looking plastic for being a Cadillac. To high a price for not being top drawer materials. I could do better buying a Buick Enclave. I owned Cadillac’s since 1977 but I am so done with what they are selling as Cadillac’s today. Even younger buyers aren’t buying. The brand is dying.
