DETROIT — Cadillac is developing a new sedan that will be larger and longer than the 2014 Cadillac XTS, making it the brand's biggest car.

The unnamed Cadillac will be built on General Motors' new rear-drive Omega platform, a source familiar with the program told Edmunds. The car is expected to debut around 2016.

"There will be lots of new innovation in the car," according to a source who asked not to be identified. He did not provide details.

Apparently, two larger Cadillac sedans above the XTS are on the drawing board.

"The Omega (platform) has been approved but this will not be Cadillac's flagship," according to the source.

A separate model that would be positioned as Cadillac's flagship "has received conditional approval," but it is not in Cadillac's future vehicle plan.

Cadillac did not respond immediately to a query from Edmunds for official word about future plans for the big sedans.

The unnamed Cadillac that is based on the Omega platform originally was expected to replace the XTS, a front-wheel-drive sedan that went into production last fall.

"At one time, the XTS was seen as a very short-term car, one life cycle, one generation, and then they would get out of it with the Omega," said the source.

A GM model cycle can range from four to five years, at which time a vehicle is re-engineered or in rare occasions dropped from the model lineup.

"The marketing guys have had second thoughts about that, that there may be a place for the XTS in the range," the source said.

In the luxury-car business, size matters. The XTS shares a front-drive vehicle platform and similar dimensions with the redesigned 2014 Chevrolet Impala. Cadillac dealers are asking for a larger sedan. Additionally, some Cadillac dealers say the XTS caters to the older, traditional Cadillac buyer and fails to lure BMW 5 Series and 7 Series and Mercedes-Benz E-Class and S-Class shoppers. Buyers of those brands favor rear-wheel drive and a sporty suspension, which is lacking in the XTS.

Cadillac does offer two rear-drive car models, the ATS and the CTS, but dealers say they need a third rear-drive sedan, a car larger than the XTS. They say a bigger rear-drive sedan is needed to compete with those models from Germany and the rear-drive Lexus LS.

The source said a second Omega-based vehicle is expected to be developed, but it is unclear whether a Cadillac flagship or a non-Cadillac model would share the platform.

"You need at least two models to make a business case" off this platform, the source said.

Edmunds says: The larger sedans have everything to do with Cadillac's global ambitions and its offensive against the Germans.
