Cadillac refuses to let its German rivals have all of the fun when it comes to high-performance. While its V-Series and V-Sport vehicles were typically well-regarded, they often fell short, for numerous reasons, over their foreign rivals. Obviously, Cadillac wants to change that equation. Last week, the new CT4-V and CT5-V made their debut appearance and just a few days afterward came the new and still unnamed performance variants. Remember, Cadillac has decided to turn the V-Series into its mid-range offerings. But the question remains: what will the ultimate Cadillac series be called?

Muscle Cars And Trucks claims multiple sources within GM have admitted "Blackwing" is the answer. Wait, isn't "Blackwing" the name of that twin-turbo V8 found under the hood of the new 2020 CT6-V? Indeed it is.

During the CT4-V and CT5-V debut presentation, GM president (and serious car guy) Mark Reuss repeatedly referenced the "Blackwing" engine name when speaking with attending media. Perhaps he was strongly hinting at something not everyone in the room realized? Quite possibly. If the Blackwing nameplate is chosen for the top dog Cadillac performance models, then the breakdown of trims will be as follows: Base, V-Series, Blackwing. The V-Sport nameplate is more than likely gone. It's also possible the "Base" will be given a unique name as well.

Again, all of this is not official at this time, but there's decently strong evidence to assume this could be the new reality. It would make sense for Cadillac to further boost not only the Blackwing engine but the name as well. The 4.2-liter twin-turbo V8 with upwards of 550 hp will remain a Cadillac-only engine. Top officials have gone on record stating they refuse to share it with other GM brands.

Also worth noting is that the engine has its own logo consisting of "two stylized wings comprised of six elongated geometric shapes." Many of the necessary pieces are already in place to turn Blackwing into a fully-fledged high-performance trim level. While the CT4 likely won't receive the Blackwing V8, it is rumored to get a twin-turbo V6. Slapping the Blackwing moniker to that vehicle would work just fine – assuming the power and performance are there. Hopefully, Cadillac will make an announcement very soon regarding its high-performance future.
