Cadillac range-topper to be named CT6, launch in 2015

New sedan to utilize lightweight materials and new body construction techniques.

Cadillac announced Wednesday that its new, high-end sedan will be named the CT6, and it will launch in late 2015.

Cadillac Chief Marketing Officer Uwe Ellinghaus described the CT6 as a competitor to "top-level large luxury sedans," a group that likely includes the Mercedes-Benz S-Class, the BMW 7-Series, the Audi A8 and the Lexus LS.

"This Cadillac will be the lightest and most agile car in the class of top-level large luxury sedans,” said Travis Hester, executive chief engineer, Cadillac CT6. "Using the lessons learned from our dynamic ATS and CTS product lines, we have developed an entirely new vehicle architecture for the CT6. It will employ a mixed material philosophy that combines the best and most efficient components optimized for each area of this new top-of-the-range car.”

The CT6 will be Cadillac's first legitimate entry into the full-size luxury sedan segment in decades. The XTS, Cadillac's largest production sedan, filled the voids left by the DTS and STS after both were discontinued.

Cadillac announced last week that the CT6 will be built in Detroit at GM's Hamtramck assembly plant.
