Lightweight Cadillac CT6 Goes Aluminum

Goodbye steel, hello aluminum. In advance of the unveiling of the all-new lightweight Cadillac CT6 at the New York Auto Show, the automaker is revealing exactly how the sedan managed to drop 198 pounds. Namely, that the CT6 will use 13 different materials, including aluminum instead of the heavy steel that made up the majority of the outgoing model.

Cadillac has announced that 64% of the new CT6 will be aluminum, as will all of the body panels and most of the body of the structure. Other materials include a variety of high-strength steels.

“The structure of the CT6 is one of the most-advanced body systems we’ve ever produced,” CT6 Executive Chief Engineer Travis Hester said in a news release. “The innovation surrounding our joining techniques have enabled us to create a vehicle structure with the highest torsional rigidity of any Cadillac while achieving one of the most mass-efficient vehicles in the segment.”

Lightweight Cadillac CT6Cadillac engineers installed “steel close-out panels” on the underbody to keep the sedan’s cabin “bank-vault-quiet.” Despite offering an incredibly quiet ride, the CT6 is much lighter than any luxury car its size.

Cadillac president Johan De Nysschen points out, “This is the rocket science of automobile construction and manufacturing today. With the CT6, we used high-strength aluminum and high-strength steels; lightweight chassis components; we integrate aluminum and steel where it makes sense; we eliminate every gram of mass possible, while achieving world-class performance.”
