Cadillac CT6 Lighter Than Similar Sedans Via Patent-Pending Construction
While the Cadillac CT6’s exterior may leave the B&B wanting, its lightweight structure may be more impressive.
Cadillac says its upcoming flagship — set to bow March 31 before rolling down the ramp at the 2015 New York Auto Show — uses 13 different materials throughout the chassis and body panels to bring the CT6’s weight down by 198 pounds when compared to a similar model using “predominantly steel construction.”
Per president Johan de Nysschen:
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.
Most of the vehicle’s structure — 64 percent — is aluminum, with high-strength steel “used strategically to reinforce” the structure, which has 21 patents pending tied to its existence. Aluminum and steel spot welds, flow drill screws, laser welding et al were used to put the structure together. The results eliminate the need for extensive sound-deadening, and allow the CT6 to be bigger and have more standard equipment “while achieving lower overall mass,” according to executive chief engineer Travis Hester.
