When Cadillac announced it will use advanced, lightweight materials and new body-construction techniques to make the 2016 CT6 flagship "the lightest and most agile car in the class of top-level large luxury sedans," I honestly thought that Travis Hester, the executive chief engineer of the car, got a little too excited with the project. Four months have passed since then and it became clear that Hester’s statement was more than just PR. As the CT6 moves closer to production, the luxury brand released detailed info of the sedan’s manufacturing process, and there are plenty of highlights to talk about.
