According to a recent report, Cadillac will introduce the XTS successor in about two and a half years.

New details are starting to emerge about Cadillac's Omega platform.

According to Car and Driver, the platform will use a variety of components from the GM parts bin and have a rear-suspension geometry that is similar to the one used on the Cadillac ATS. It could underpin models as small as the BMW 5-Series or as large as the long-wheelbase BMW 7-Series.

The first model to use the platform will reportedly be the XTS successor. While that particular car hasn't even gone on sale yet, the new sedan could be launched in two and a half years.

Motivation will reportedly be provided by a 3.6-liter V6 engine with approximately 310 hp (231 kW / 314 PS). There could also be an optional V8 as well as a hybrid powertrain. Regardless of which engine is selected, it will likely be connected to an eight-speed automatic transmission. Rear-wheel drive will be standard, but all-wheel should be optional.

Later on, Cadillac could use the Omega platform to underpin a large crossover and a coupe. There's also word of a flagship sedan, but it remains unclear if it will be a bespoke model or just a stretched version of the XTS successor.
