Cadillac announced this week they would again build a rear-wheel drive flagship above all current models they offer now, and it will be built in Detroit.

To start rolling off the assembly line late next year as a 2016 Cadillac, the yet un-named flagship will be built at the Detroit-Hamtramck assembly plant where the ELR is currently built.

A well kept secret, the new top-of-the-range Cadillac will be built on an all-new rear-wheel drive architecture and be of an all-new design from the ground up.

Little is known about the new Cadillac as it relates to what engines will be available or what configurations it might be sold in be it sedan and coupe or even convertible.

I mention the latter two because Cadillac has teased us in recent years with the Ciel and ElMiraj concept we’re showing you here. These show us the full size and design Cadillac has been hinting of for a new flagship model.

We can bet that the new twin-turbocharged 3.6 liter V6 we recently tested in the CTS V-Sport will be available, but what beyond that is anyone’s guess at this point.

The new model will be unveiled in the first half of next year. My bet would be at the North American International Auto Show in Detroit come January given its where the car will be built.

It may however wait until the New York Auto Show in April as the brand is rumored of late to be taking a liking to the Big Apple in ways that have yet to be officially announced.

Wherever it debuts, a new top-of-the line Cadillac will be huge news and we’ll bring it to you when it comes.
