Update 2: Cadillac CEO Johan de Nysschen participated in a Q&A on Jalopnik and shed light on the engine options of the CT6. He said -
We have an entirely new family of V6 engines coming soon, premiering in CT6. We will release technical details of this next month.
de Nysschen also spoke about a new twin-turbo V8 engine that is Cadillac developing for the CT6 -
We are carefully planning the life cycle of CT6, and this must include some high-power derivatives as well. The lightweight body structure allows us to achieve formidable performance even with a twin-turbo V-6. Imagine how this car would perform with a twin-turbo V-8.
He stated that the car's price positioning would be above the XTS and CTS, but did not share specific details. On the subject of downsizing, he opined that Cadillac will have to get the market accustomed to pay for performance, and not horsepower.
Update 1: Indian Autos Blog is informed that the Cadillac CT6 will be revealed on March 31 2015, a day prior to the New York Auto Show.
Could be powered by a 3.0-liter twin-turbo V6.
A Cadillac commercial aired during the Oscars shows a new, unseen model, which is believed to be the Cadillac CT6. The CT6 is expected to be revealed later this year, and should go on sale in the United States next year. The car's video premiere is accompanied by the text "How dare a 112-year-old carmaker reinvent itself".

The CT6 is reported to kickstart the brand's new 'CT' naming for cars and 'XT' for SUVs. The CT6 will be Cadillac's long rumored flagship sedan, and is expected to be lighter than the current CTS even. A 3.0-liter twin-turbocharged V6 with a hybrid drivetrain should form the core of the CT6, with a standard rear wheel drive layout.
Engineers are reported to have upped the content of aluminium in the CT6's body to arrive at a competitive weight, yet provide high stiffness. Cadillac on their part are yet to give out any details on the CT6, but an unveiling at the New York Auto Show in April is certainly a possibility.
