DETROIT — The 2016 Cadillac CT6 flagship luxury sedan makes extensive use of aluminum in an effort to save weight and boost fuel efficiency, GM said before the car's official debut on March 31 at the 2015 New York Auto Show.
"Sixty-four percent of the CT6 body structure is aluminum, including all exterior body panels — and the mixed material approach saved 198 pounds compared to a predominantly steel construction," GM said in a statement.
The muscular-looking CT6 uses 13 different materials "customized for each area of the car to simultaneously advance driving dynamics, fuel economy and cabin quietness," according to the automaker.
"The structure of the CT6 is one of the most advanced body systems we've ever produced," said Travis Hester, Cadillac CT6 executive chief engineer, in a statement.
The EPA has not rated the CT6.
Some steel is used in the CT6. The vehicle underbody uses steel close-out panels on the lower structure to create "a bank vault-quiet cabin without the added weight of sound-deadening material," GM said.
Edmunds says: Cadillac wants luxury buyers salivating over the CT6, so it's serving up a few juicy details before the main course arrives later this month.
