How does the CT6's all-aluminium body weigh just 380Kg?

When it comes to aluminium bodies, one has to think of the Cadillac CT6, which is built on GM's Omega rear-wheel-drive platform and weighs only 1.7 tonnes, while the body-in-white weighs only 380Kg. 57% of the body frame is made of aluminium, which is 100Kg lighter than a pure steel body and can be said to be the best in its class. It is a leader in its class.

For the emotional person, the evaluation of a car may be more from the perspective of design or even history, while for the rational person, the evaluation of a car may be very data-oriented, usually from the "three major components" of the car, but the "base body" of the vehicle is equally important. "The body-in-white is often overlooked.

This bodywork is not the same bodywork, what is the white you are talking about? In fact, body-in-white is the bodywork before it has been welded but not painted, excluding the various decorative parts, which in layman's terms is equivalent to a bare shell. Some are steel, some are aluminium, and some are carbon fibre. In fact, it is not difficult to see that the aluminium body, whether in terms of technology or cost, is more advantageous than the steel body, especially in terms of safety, in many people's traditional concept, or simply that the heavier the vehicle, the higher the safety of the vehicle, in fact, this concept is very wrong.
