While it was originally thought that at least one of these models would receive the 4.2-liter, twin-turbocharged Blackwing V8 that made its first appearance in the 550-horsepower CT6-V, we now know that won't be the case.
While it might make all the sense in the world to sling a Blackwing V8 between the fenders of these Blackwing-named models, we're not mad at rumors suggesting they'll will receive engines based on the powerplants found in the outgoing ATS-V and/or CTS-V models.
That could mean both more displacement and more power.
The best part? Cadillac has confirmed that both the CT4-V and CT5-V Blackwing models will come standard with manual gearbox, something of a rarity in new models these days. An automatic transmission option is promised, with rumors suggesting it'll be GM's new 10-speed unit.
Cadillac's model naming scheme has been a bit of a muddled mess for years. Now, they seem to be doing much the same as Mercedes-AMG did with the "AMG Sport" badge, taking what would have been called a V-Sport a few years ago and folding it into the now-larger V family.
Confusingly, of course, they're now adding "Blackwing" as an additional designator for the highest-performing variants in their model ranges.
