General Motors said this 4.2-liter, twin-turbo V8 would be a "Cadillac-exclusive" engine.


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 (or is that CT5-V?). The source also said the V8 is slated to show up in the 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 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 . So it stands to reason this V8 might also find its way into some sort of Corvette model -- whether front- or midengined.

The next-generation CTS is expected to arrive sometime in 2019, with the V model following shortly thereafter.
