Chassis Construction
Static and Dynamic Rigidity
The new Jetta sets new standards for static
and dynamic rigidity by the application of
lightweight design principles.
Fenders, doors and side panels are all made
of high strength steel.
Laser Weld Technology
The assembly plant in Puebla, Mexico
makes extensive use of laser welding
technology to produce the new Jetta
chassis. The increased use of laser welds
has resulted in significant improvements in
chassis strength and rigidity.
Laser weld technology not only improves
manufacturing efficiency, it also improves
the quality of the chassis by increasing the
welded surface while reducing the
deformation of the sheet metal caused by
the necessary heat and pressure of
previous welding methods.
The chart below provides a comparison of
increased manufacturing technology on the
new Jetta A5 compared to the previous
Jetta A4.
