Is there any big improvement in manufacturing technology between the new Jetta and the old Jetta? I hope professionals will talk about it.

In terms of production technology, the new Jetta still inherits the excellent quality of Volkswagen. Precision, stability, texture and thickness are the labels of Jetta. However, this time, the new Jetta has made great efforts to build a solid body that meets the highest collision standard of C-NCAP, which can bring drivers the comprehensive safety protection of the new Jetta. In addition, the new Jetta technology is more advanced and scientific from the following aspects.

First of all, the reasonable body size ratio makes the brand-new Jetta body more elegant and improves the quality. Secondly, the new Jetta adopts strict body quality control, which ensures the safety performance of vehicle collision and creates more excellent power and fuel economy. In addition, the roof and side walls of the new Jetta body are welded by laser, which improves the rigidity of the whole vehicle. Compared with the car body with top cover sealing strip, it is not only beautiful, but also reduces wind noise. The new Jetta floor and longitudinal beam adopt laser tailor-welded steel plates, which reduces the weight of the car body and improves the collision safety of the whole car.
