Great Designs in Steel 2016 Presentations: A Closer Look - 2016 Chevrolet Malibu and 2017 Buick LaCrosse
In case you missed it Terry A. Swartzell from General Motors Company presented “Lightweighting and steel technologies in the all-new 2016 Chevrolet Malibu and the 2017Buick LaCrosse” at Great Designs in Steel 2016.
“One underbody fits all” is no more. While the ’16 Malibu and the ’17 LaCrosse share a common “platform”, each has certain areas of the structure that are unique to each vehicle. So a repair that may be possible on one vehicle may not apply to the other even though they share a common “platform”.
MIG brazing has also surfaced in these models. The MIG brazing allows for single sided joining and allows for smaller, stiffer sub-assemblies. Per the 2016 Chevrolet Malibu body repair manual, “Note: MIG Brazing Welds equivalent to the factory brazing welds are recommended.”
The right steel grades in the right areas! GM has increased the usage of HSLA, dual phase and multi-phase, bake hardenable, and PHS and martensite. In addition to the continued use of scalloping most of the mating flanges.
