Being a Cadillac means superior refinement over lesser makes and models, with better design and engineering. And with the Cadillac ATS and new 2014 CTS — both members of the GM Alpha Platform family — those expectations are ensured by design, with clever usage of structural adhesive and aluminum.
In the case of structure adhesive, the all-new 2014 Cadillac CTS uses 387 feet of it — more than the length of a football field. In effect, the material provides a damping effect of sorts, which in turn reduces the amount of vibration through the body structure of the vehicle, thus resulting in fewer vibration and harshness for the vehicle’s driver and occupants. The adhesive (and usage of high-strength steel) also contributes to a 40 percent stiffer chassis for the new CTS compared to the outgoing model.
Meanwhile, the use of aluminum contributes to a relatively light base curb weight of 3,600 pounds — 200 pounds lighter than a BMW 528i, making the 2014 CTS the lightest car in the midsize luxury sedan segment.
Compared to the 2013 CTS, the all-new 2014 CTS saves weight in the following categories:
- 13.1 pounds by utilizing aluminum over steel bumpers
- 55 pounds by replacing the steel door panels with aluminum panels
- 14 pounds by making front strut towers of cast aluminum compared with steel used in 2013 CTS
- 7.2 pounds from the IP structure, where extruded and stamped aluminum replaced cast magnesium
- 36.5 pounds by using extruded and cast aluminum vs. a steel powertrain cradle on the current model
