General Motors developed the rear-wheel-drive Omega platform specifically for Cadillac and the brand immediately put it to good use with the impressive Cadillac CT6 sedan. Anyone familiar with GM knows the automaker typically uses a single platform for a number of different vehicles, but strangely, the CT6 is so far the only vehicle to use the Omega architecture.
It turns out that Cadillac had much bigger plans for the Omega platform before cost constraints forced the company to go in another direction. As first reported by GM Authority’s sister site, Cadillac Society, company management made a business case for the large rear-wheel-drive platform by planning to use it in three separate vehicles: the CT6, an unnamed “Lux 3” mid-size sedan and a “Lux 4” three-row crossover – the latter of which turned out to be the XT6.
Cadillac eventually abandoned its plans for both the “Lux 3” sedan and the Omega-based XT6, sticking the crossover on a much more affordable crossover platform, the C1, which is shared with seven other GM crossovers. While the XT6 is an acceptable entry into the premium/luxury crossover segment, there’s no denying it would have been a much more impressive product had it arrived on the Omega platform. The latter enables both RWD and RWD-based AWD, is extremely light and has 50:50 weight distribution. This would have made the XT6 a true rival to German offerings like the BMW X5 and Mercedes-Benz GLE, rather than a premium FWD-based offering like the current model, which compares better to vehicles like the Acura MDX.
That said, Cadillac seems to have moved on from the Omega platform, anyway. The CT6 is no longer in production in North America and Cadillac focused on its upcoming electric vehicles. In fact, electrification was a factor explaining why the Cadillac XT6 went to C1 in the first place, with GM pulling much of the brand’s resources forward and funneling them into its new EV projects.
In light of the Cadillac’s impending shift to EVs, Omega was deemed a dead end and was put to pasture in favor of more affordable platforms. According to Cadillac Society‘s sources, the BEV3 electric platform and new VSS-R rear-wheel drive platform will both implement lessons GM learned when developing Omega, so at least the effort wasn’t a total waste.
The first Cadillac EV will be a mid-size crossover, which the automaker released design renderings of in early 2019. The electric crossover is expected to go on sale in 2022, though we are expecting it to debut in April.
