Cadillac Sings Ode To New 550HP Blackwing V8 Engine In Film

The all-new “Blackwing” 4.2-liter twin-turbo V8 engine is a big deal for Cadillac and for General Motors as a whole.

A clean-sheet design, the power plant has twin-scroll turbochargers housed inside the “V” of the engine (in a so-called “hot-vee” layout), allowing for more compact packaging and, more importantly for the driver, less turbo lag.

When Cadillac announced the all-new CT6 V-Series last year, it said the Blackwing V8 produces up to 550 horsepower (558 PS) and 627 lb-ft (850 Nm) of torque. Cadillac didn’t reveal where in the rev range the maximum power and torque kick in but said the engine has been optimized for a smooth, flat power curve.

In the 2019 CT6 and CT6 V-Series, the engine is hooked to a GM’s Hydra-Matic 10-speed automatic transmission (10L90) that drives all four wheels.

The new 4.2-liter unit is also available in a lower state of tune of 500 hp (507 PS) and 553 lb-ft (749 Nm) of torque in the 2019 CT6. No other performance specs have been announced so far but chances are the Blackwing will help make the 2019 CT6 V-Series an interesting alternative to the Mercedes-AMG S63 and the upcoming Audi S8.

For now, the CT6 remains the only car officially announced to feature this engine. However, rumors about GM fitting this power plant inside the upcoming mid-engine Corvette C8 have been going around for quite a while now. The fact that it’s hand-built in Bowling Green, Kentucky (the home of the Corvette) certainly helps these rumors gain traction. Not to mention that even the Blackwing logo reminds of the Corvette.

Until official confirmation arrives, check out the following video Cadillac dedicates to the Blackwing V8. We promise you’ll be excited.

    What other twin-turbo V8 is built by GM? No one. So, here we have the Corvette C8 engine

    • Merc1

      Yeah I was thinking that too since they say “our latest turbo V8”. As always with GM, there is a lot of BS in everything they do. The Corvette version is rumored to be a 5.5L version.


    • eb110americana

      GM already stated that this engine will be Cadillac-exclusive, and not in the Corvette. A 5.5L relative may be the engine featuring in the C8 Vette, but it is very different, if it is related at all. Leaked CAD work shows that it is not a “hot-V” setup, but one with conventional twin-turbos mounted outboard.

    On paper this power plant looks to be exceptional. Can’t wait to see the numbers the CT6-V posts with this beast.

  • Merc1

    Great, have you figured out where the CT6 will be built yet, or if even production is continuing?


    • Rocket

      China. Very quietly, of course. A Made in China label doesn’t exactly scream “American Luxury Flagship” after all.

      • Merc1

        I just can’t see it. All the flag waving GMers are going to go for a Chinese made Cadillac?


        • Rocket

          I’m sure some will. It’s called blind loyalty for a reason. Besides, where else will they build it? The CT6 is already being made in China. If they’re keeping it in the lineup, it’s the only thing that makes sense.

          I’ll wager they’ll try importing it, and if numbers continue to fall they’ll just kill it in the States.

    Escaladeeeeeee at least as an option

  • Thetruthísntalwayspopular

    The engine looks great: now build some sexy cars to put it in. How about a Buick Riviera on Omega please?
