2014 Corvette Stingray: new design videos

Two new official videos on the 2014 Corvette Stingray, documenting the design process behind the interior and the use of lightweight, shape memory alloys.

Smart materials

Weighing 99 pounds less than its predecessor, the 2014 Corvette Stingray uses a General Motors’-developed lightweight shape memory alloy wire in place of a heavier motorized actuator to open and close the hatch vent that releases air from the trunk. This allows the trunk lid to close more easily than on the previous models where trapped air could make the lid harder to close.

Considering there are about 200 motorized movable parts on the typical vehicle that could be replaced with lightweight smart materials, GM is looking at significant mass reduction going forward.

Shape memory alloys – typically made of copper-aluminum-nickel or nickel-titanium – are smart materials that can change their shape, strength, and/or stiffness when activated by heat, stress, a magnetic field or electrical voltage. Shape memory alloys “remember” their original shape and return to it when de-activated.

In the new Corvette, a shape memory alloy wire opens the hatch vent whenever the deck lid is opened, using heat from an electrical current in a similar manner to the trunk lights. When activated, the wire contracts and moves a lever arm to open the vent, allowing the trunk lid to close. Once the trunk lid is closed, the electrical current switches off, allowing the wire to cool and return to its normal shape, which closes the vent to maintain cabin temperature.

“Smart materials like shape memory alloys offer new possibilities for many movable vehicle features,” said Jon Lauckner, GM’s chief technology officer. “These new materials enable innovative designs and new and improved features at a lower cost than traditional motors and actuators.”

Shape memory alloy also helps remove unwanted mass, which can help improve vehicle performance and fuel economy. The wire actuator used on the new Corvette is approximately 1.1 pound (.5 kilogram) lighter than a conventional motorized system.

“The shape memory alloy used on the new Corvette represents nearly five years of research and development work on smart materials for which GM has earned 247 patents,” said Paul Alexander, GM smart materials and structures researcher.
