A new report indicates Cadillac’s upcoming CT6 flagship model will feature an all-aluminum body.

Set to ride on GM's newly developed rear-wheel drive Omega full-size platform, the CT6 will reportedly get an aluminum body which according to Automobile Magazine will enable the model to have a curb weight similar to the CTS (3,700 - 4,100 lbs) despite being larger. The design of the body will be evolutionary so don't expect any influences from the jaw-dropping Elmiraj concept.

Other details are scarce at the moment but the report does mention power could come from a new V8 engine which will be sold alongside lesser four- and six-cylinder motors that will probably be the bread and butter for Cadillac. We already know the model is going to be offered with a "streaming video mirror" featuring a 1280 by 240 pixel TFT-LCD display with a pixel density of 171 PPI.

The name of the car comes from Cadillac Tourer 6, with the figure denoting it will be priced and sized between an Audi A6 and A8 / BMW 5-Series and 7-Series. It won't remain Cadillac's flagship model for a very long time as a bigger S-Class-rivaling CT9 (name not confirmed) is already in the works.

The Cadillac CT6 will be unveiled in April at the 2015 New York Auto Show and should go on sale towards the end of the year as a 2016MY.
