Cadillac's Big CT5 Mystery Has Finally Been Solved

Technology / 1 Comment

We had our suspicions and now there's an answer.

The 2020 Cadillac CT5 is not exactly entirely new because it still rides on the same though an updated version of GM's Alpha platform that also underpinned its immediate predecessor, the Cadillac CTS. This rear-wheel-drive architecture also serves as the basis for yet another important GM performance car, the Chevrolet Camaro. Thing is, there's an all-new and more advanced platform Cadillac has at its disposal, Omega. In fact, the just discontinued Cadillac CT6 utilized this platform, which was also capable of accommodating the 550 horsepower Blackwing V8 engine. Given the amount of time and money Cadillac invested in Omega, why didn't it also underpin the CT5?

Cadillac Society has confirmed what we've long suspected: GM's luxury brand decided to invest those development funds elsewhere: electric vehicles and autonomous technology.

Earlier, we also learned the Omega platform as the original plan for the Cadillac XT6 three-row crossover but, again, it was axed for the same reasons. As such, the CT5 was developed with updated Alpha 2 while the XT6 utilizes the CT1 platform.

In other words, the CT6 has, so far, been the only Caddie to be underpinned by Omega. Ever since we found out the CT5 won't receive the Blackwing V8 for a high-performance variant because it won't fit, cost-cutting measures related to using the existing platform were suspected.

It's not all bad news for the CT5, however. We also reported the upcoming top dog CT5 performance trim will likely come powered by the same 6.2-liter supercharged V8 found in the C7 Corvette Z06. A six-speed manual transmission is also likely. The fact that the Omega platform isn't currently being used for any other model is both surprising and disappointing. It is the most advanced vehicle architecture GM has ever built due to its mixed-metal composition resulting in a lightweight structure, among many other things. In fact, 21 new patents were filed during its development.

So, how will Omega be utilized in the future? Right now, it's anyone's guess.
