Report: XT6 Was Supposed to Use CT6 Platform. Could’ve Had a V8?

Cadillac’s XT6 crossover shares it’s C1 platform with GM’s other three-row crossover like the GMC Acadia and Buick Enclave. But a new report from Cadillac Society suggests that it wasn’t initially supposed to be. A change that may have robbed us of the most interesting possible XT6 variants of all.

The General Motors Omega platform was originally conceived for three vehicles, a large sedan, a midsize sedan, and a three-row crossover. The large sedan became the CT6, a great-driving big car that has just seen production for North America wrap up.

The Omega platform was designed for Cadillac specifically, with a longitudinal engine, near 50/50 weight distribution, and, we presume, other luxury-specific features in mind. That Omega platform could also have meant some other, more interesting variants of the XT6. Like, for example, one that used the 4.2L twin-turbo Blackwing V8 of the CT6-V in place of the 3.6L V6 that’s the only choice in the C1-based XT6 we got. An XT6-V would certainly have been an interesting competitor to the likes of the BMW X5M and even Audi’s RS6 Avant.

Why the change? The report says that it was cost and business decisions that lead Cadillac to the platform used by seven other GM crossovers. The need for Cadillac to transition to electric in a hurry meant that resources were better used there. Which, given the XT6’s strong sales, doesn’t seem to have hurt it on the showroom floor. It just leads us to dream of what could have been.
