  • 4.2L Motors Built By 1 Person

    Here is an interesting article about BGA’s Powertrain Build Center (PBC) employees building the Cadillac’s 4.2L, TT motors. Just six employees in total will be building it, yet each motor will be completely assembled by just one of them. This makes sense in that the estimated annual take rate is around 2,000-3,000 CT6’s. However, that motor is also going to be later installed into the 2021 Cadillac Escala and perhaps other Cadillac. All this fits with BGA expanding the PBC right about now.So what does this say for the ME for 2020? I personally believe, “nothing” — at least not for the 2020 model year (MY), for my opinion is that we are only getting one motor option for 2020 (the LT1+.) However, we know we will be getting more powerful motors for the 2021+ Z06, the ZR1/ZORA C8 versions, and just like now, those too would be hand assembled by one PBC employee. Or hopefully, the Engine Build Option will also resume at some point so you could assemble your own motor under the tutoring (if/as necessary) of your PBC Guide Builder. We also do not know if even for the LT1+ for 2020 (and/or later), one might be able to select the Engine Build Option. Here below, is what we know; much of it, IMO will transfer to our ME motors down the road for 2021 (and maybe even sooner). We do know that the Enigne Build Option will resume at some point for the more powerful of the C8’s motors.

    Just Six People Will Build Cadillac’s 4.2L LTA Twin-Turbo V8 Engine (By Sean Szymowski)

    Cadillac will once again offer its own exclusive engine when the 4.2-liter DOHC twin-turbo V8 engine begins production for the 2019 CT6 sedan. Matching its exclusivity will be the small team of employees tasked with building the powerplant.

    Popular Mechanics reported Tuesday that a team of six workers will be assigned to build the 4.2-liter LTA V8 engine. However, only one worker will assemble one engine by hand at a time. Production will take place at the Bowling Green, Kentucky, assembly plant where other workers assemble General Motors’ small-block V8 engines used for the C7 Corvette.

    Jordan Lee, chief engineer for the 4.2-liter V8, told the publication that the new engine won’t be raucous like drivers may remember with small-block V8-powered Cadillacs such as the CTS-V. Instead, the new engine is meant to compliment the CT6’s extra weight with a silky response and less drama.

    “The engine is biased toward torque versus peak power,” he said.

    That doesn’t mean it will be a slouch, though. In its regular output, the engine makes 500 horsepower and 553 pound-feet of torque. Stepping up the 2019 Cadillac CT6 V-Sport will see the engine produce 550 hp and 627 lb-ft of torque.

    We’ll likely see the engine make its way into many future Cadillac vehicles. The next-generation 2020 Escalade and new CT5 sedan seem like primary contender.
