Mark you calendars, because what promises to be the most powerful production Cadillac ever is set to be revealed in less than a month’s time.

Last April, Cadillac confirmed that it would launch the Blackwing versions of its CT4-V and CT5-V. Now, according to Cadillac Society, who cites sources familiar with the matter, the CT4-V Blackwing and CT5-V Blackwing will debut on February 1.

Although the CT4-V and CT5-V were launched in 2019, they are the tamer, more approachable sporty sedans. Like Audi’s S models, or, say, BMW‘s M340i, the V-Series are an entry point in the sporty sedan lineup. The Blackwings, meanwhile, are more akin to Audi’s RSs or BMW’s full-blown M cars.

Cadillac has revealed that the Blackwings will get magnesium wheels, carbon-fiber sports seats and 6-speed manual transmissions, but little more has been officially shared.

Reports suggest that the CT4-V Blackwing will make use of GM’s twin-turbo 3.6-liter V6. That’s the same engine used by its predecessor, the ATS-V, in which it made 464 hp and 445 lb-ft. The CT5-V Blackwing, meanwhile, will reportedly get a supercharged LT4 6.2-liter V8. Again, that’s the same mill its spiritual predecessor, the CTS-V, used. In that case, the engine made 640 hp and 630 lb-ft of torque.

The engine has other homes, though. Specifically, in the Chevrolet Camaro, where it makes 650 hp and 650 lb-ft of torque and is paired to either a 6-speed manual transmission or a 10-speed automatic.

The Blackwings, apparently, won’t be sold in Australia or China.
