It’s safe to say the new Cadillac CT5-V and CT4-V were a smidge disappointing. However, these two cars are not direct replacements for the beasts that were the CTS-V and ATS-V.

Instead, Cadillac is launching a two-tier V-Series strategy and teased the true next-generation V models at the Detroit Grand Prix this past June. According to GM Authority information obtained roughly a month ago, these cars will add the “Blackwing” moniker to their names for a full title of Cadillac CT5-V Blackwing and CT4-V Blackwing.

Now, there’s new information from Motor Trend’s Jonny Lieberman that despite the use of the “Blackwing” name, the twin-turbo 4.2-liter LTA V8 Blackwing will not be part of the formula. Instead, Lieberman shared on his personal Instagram page that the CT5-V Blackwing will feature the CTS-V’s 6.2-liter LT4 supercharged V8. He added output is likely to increase marginally from the CTS-V’s 640 hp to perhaps as much as 670 hp.

More good news: there will be a manual transmission offered. A row-your-own option appeared to be missing from the CT5-V and CT4-V shown in June.

As for the CT4-V Blackwing, it’s expected to also borrow an engine from the past: the 3.6-liter twin-turbo V6 LF4 that served the ATS-V. As Lieberman noted, that’s a shame since the 6.2-liter LT1 V8 would be a lovely powerplant here. It too will pack a manual transmission more than likely.

Carryover powertrains have long been rumored for the next-level of V-Series cars. If both cars do bow without a Blackwing V8 under the hood, it will leave the CT6-V as the only model on sale with the hottest version of the DOHC twin-turbo V8.

It’s unclear when we’ll see the hopped-up sedans debut, but with the regular CT5-V and CT4-V just revealed, we imagine Cadillac will let its banner sport sedans bake a little while longer.

And to top it all off, Lieberman also stated that, despite previous reports, the next-level CT4-V and CT5-V might not use the Blackwing name.
