  • 4.2L Blackwing Going Into C8?

    The Blackwing motor that is still going in the CT6-V until June, will not go to waste, instead going into the Cadillac Escalade and the next CTS-V. Might it being going into a future ME Corvette, say the 2021+ Z06?

    It sure is an amazing motor, a 4.2L, twin turbo, “hot V” 32 V, DOHC engine making 550 HP and 627 TQ. Would love for it to be in my second Corvette ME!

    GM's 'Cadillac-exclusive' V8 will likely end up in next CTS-V, Escalade
    Cadillac's 4.2-liter, twin-turbo V8 was originally slated for the CT6 V-Sport. *(By Stephen Ewing) Earlier this year, Cadillac introduced a brand-new, 4.2-liter, twin-turbo V8 engine. This "Cadillac-exclusive" engine was originally scheduled to arrive under the hood of the CT6 V-Sport. But with the recent announcement that the CT6 will end production, what will happen to this powerful new motor?

    A source close to Cadillac told Roadshow on Thursday that this new V8 will likely end up under the hood of the next-generation CTS-V sedan (or is that CT5-V?). The source also said the V8 is slated to show up in the Escalade SUV.When Cadillac announced the CT6 V-Sport at the 2018 New York Auto Show, it said the 4.2-liter V8 would produce 550 horsepower and 627 pound-feet of torque. That doesn't quite match the current CTS-V's 640 hp and 630 lb-ft from its 6.2-liter supercharged V8, so the 4.2-liter engine would likely get a small power bump for this application.

    The Escalade, meanwhile, uses a naturally aspirated 6.2-liter V8 that makes 420 hp and 460 lb-ft of torque, so the 4.2-liter engine would probably be detuned slightly. Unless there's, like, an Escalade-V in the works. Which would be freaking awesome.

    Cadillac's 4.2-liter V8 will be hand-built at General Motors' Performance Build Center in Bowling Green, Kentucky, which is also the home of the Chevrolet Corvette. So it stands to reason this V8 might also find its way into some sort of Corvette model -- whether front- or midengined.

    The "availability" of the Blackwing rose significantly since GM announced the demise of the CT6-V earlier this week. As I have said a coupla times since then, that increased the chances of it being the base model engine for the 2020 C8 IMO. Heck its even built in Bowling Green!

      They even expanded the Powertrain Build Center (PBC) inside BGA and hired extra and dedicated employees just to build the Blackwing. The expansion of the PBC has been gobbling up the old paint shop’s abandoned space.

        Good info. Lets talk it up. Pull your strings John so the 2020 base ME has the Blackwing! I think that would put demand for the 2020 ME thru the roof.

          Several years ago a Corvette executive stated that there was no ME Corvette or that he knew of none. But there was at that time a ME and surely he knew. Several months ago a Cadillac executive stated that the 4.2 liter TT V8 (Blackwing) was Cadillac exclusive and implied that he was, more or less, unaware of a ME Vette.

          Seems like a pattern. Also there is very effective, tight security and secrecly all over the program. No one admits to knowledge of any meaningful detail first hand. Nevertheless, there is authoratative rumor that the first release ME will surely come with the push rod small bloc. Seems like a pattern of well intnded misinformation in support of a tight and effective security effort.

          This could all be an effort at verbal camoflage: 1) No ME. 2) Cadillac exclusive Blackwing. 3) LT1 powertrain. 4) no formal release of any information nor acknowledgement. A good hearted effort to render an ultimate, pleasing shocker.


          But for the risk of massive disappointment, there is an inclination to expect that a version of the Blackwing will be the ME straight out the gate. If the bore is increased, the stroke shortened and the boost elevated, then the RPM, HP and TQ can be moved up in performance.

          Since the research and developement of the Blackwing has already been paid, then what is the difference in the cost of parts and assembly between the two engines? Is the difference a few hundred or few thousand $ ? Is it a difference that buyers will be glad to pay.

            Above is a very insightful post Sheep Dog! Thank you very much.

            I would love that motor in my ME.

              Yes pull some strings John ....that’s one bad *** engine and the corvette deserves it and needs it. Base with the Blackwing there goes the MSRP. But you only live once. So why not !!!

                How much more than a 6.2 V8?

                  Interesting that while there are so many ME rumors, many I believe to be real facts from highly informed insiders, yet all are about non-powertrain information. We are truly “best case guessing” at this point when it comes to the 2020 ME’s powertrain, or kind of like a pilot’s term of “flying blind.”

                  The only thing I have been able to confirm about the 2020 ME’s powertrain are two things, e.g., that it is a V8 and that its development work was initially finished a while ago.

                  However, my predictions, based solely on rumors and thus could be all wrong, are that the 2020’s ME powertrain:

                  * Is ased heavily on the LT1, but modified/advanced enough (six years learning), that it has its own code number, perhaps LT2?

                  * Has more power than an LT1 (but whether than means 475 or 511 HP is not known;

                  * Has torque in that same 475-500+ range;

                  * Is a OHV, 16V, naturally aspired engine;

                  * It’s size is either 5.5L or 6.2L.

                    My guess is the Blackwing is gonna show up.

                        I think it would be an engine more suited for the base model and not the z06, the current gen z06's engine is already better, in terms of HP and TQ. Would be disappointed if the next gen z06 had 100 less HP than the previous gen.

                          True, If one were to talk about numerical bragging rights, the LT4 is a clear winner over the Blackwing.

                          However, the functional capabilities, both straight line and accelerating out of a corner, of a ME with a DCT and a Blackwing with 100 less HP and 23 less TQ than the C7 Z06’s LT4 , well, to put it bluntly, the ME would kick the C7 Z06 in the rear (and I own a C7 Z06). Numbers of HP and TQ are way secondary to having both a DCT transmission, and the ME having the weight of the combined transmission/motor/diff right over the driving wheels.

                            But would a ME with a blackwing kick a ME with the LT4's butt? I'm not so sure about that one.

                              My apologies if I misunderstood your post, but the chances of a LT4 going into an ME are about as great as its weight being under 3,000, e.g., none.

                              GM has moved beyond superchargers and into either NA’s, or for high perf versions, either twin stage, 32V, DOHC twin turbos or, eventually all electrics.
