The 2015 Cadillac ATS Coupe Body Structure makes liberal use of aluminum, magnesium, high-strength steel, and ultra-high-strength steel.
View of a bare ATS white body’s engine compartment reveals fully braced cast-aluminum strut towers and fabricated aluminum engine cradle with beautifully cast magnesium multi-point engine mounts. The cross-car beam is a tubular aluminum fabrication.
Underbody aerodynamic shields are common place on sedans and crossover vehicles to improve fuel ecomony. Often these shields are made from plastic and can be easliy removed to provide acess for struts on a side resting vehicle. Just something to keep in mind.
