The quest for better, faster, stronger, and lighter is a continual game in the automotive arena these days and Cadillac has worked some engineering magic into the new ATS and upcoming CTS sedans.
Materials like aluminum, magnesium, high-strength steel, and structural adhesives help comprise the cars’ structures. The technology was used so extensively in the upcoming CTS that Cadillac managed to shave 200 pounds from the curb weight, despite it growing 4.2 inches in overall length from the outgoing car.
Items like the doors, bumper supports, instrument panel structure, and powertrain cradle are all cast from aluminum. Even the front strut towers are aluminum. Over 36 pounds was cut from the powertrain cradle alone, and an impressive 55 pounds from just from the doors – all by swapping out materials.
The new CTS’ base curb weight is now the lightest in its class at 3,600 pounds.
“Reducing overall weight is a key element in producing a car that delivers agile handling dynamics,” said John Plonka, CTS program engineering manager. “By rethinking very traditional elements, such as such as materials used for bumpers and doors, we are able to save precious weight and stay true to delivering a vehicle that is fun to drive.”
The CTS also boasts some 387 feet of structural adhesive that bond together and stiffen many load-bearing components. The football field-length of glue also provides a damping effect that reduces any squeaks, rattles, or harsh noises from entering the cabin.
With all the advancements in lighter-weight materials, the CTS is said to be 40 percent stiffer than the current model, which should pay dividends at the track. We look forward to experiencing the performance of the new materials within a quiet cabin and sharp handling once we get behind the wheel of both sedans.
