#BlackwingV8

General Motors’ 4.2-liter, twin-turbocharged Blackwing V8 made waves when it appeared for the 2019 model year, but its applications have so far been limited to only the most potent versions of the Cadillac CT6 — a sedan whose lifespan may soon come to an end.

Many argued that the Blackwing was unnecessary, as GM already has a long list of engines beginning with “LT” from which to choose. And choose it might, as a new report suggests GM has no use for the Blackwing.

With the 2019 Cadillac CT6-V drawing its power from General Motors’ new 4.2-liter twin-turbo V8, it was only a matter of time before people started wondering where else the “Blackwing” motor might crop up. Thus far, the engine has only appeared in the CT6 sedan — producing an impressive 550 hp and 627 lb-ft of torque.

Future models are likely to include the brand’s Escalade SUV, but the luxury brand wants to put the kibosh on any rumors that the Blackwing will be available under another brand. When asked if the motor would be a cross-brand system by Motor Trend, Cadillac President Steve Carlisle responded with “over my dead body.”

We’ve hinted at this before, but now there’s order guides and pricing to share. While Cadillac’s CT6 flagship sedan will soon be without a home, General Motors hasn’t said anything about dropping the model. Once Detroit-Hamtramck Assembly shuts off the lights, GM would like to source its full-size sedan from some other place, be it China or another U.S. factory.

In the interim, there’s a new engine poised to appear beneath the sedan’s hood.
