Hyundai Elantra and Adhesives
November 19, 2015
The reveal of the 2017 Hyundai Elantra at the LA Auto Show yesterday included an emphasis on something that isnât ordinarily spoken of in such settings:
Yet during his portion of the introduction of the sixth-generation Elantra, Mike OâBrien, vice president of corporate and product planning for Hyundai Motor America, said that he happens to be a pilot and so is greatly appreciative of technologies that can be strong, safe and light, and that airframes are transitioning from riveting to bonding.
Similarly, the engineers who developed this new car were also keenly interested in strength, safety and low mass, so this new car makes extensive use of structural adhesives.
And âextensiveâ means âextensive.â Theyâve increased the amount of bonding on stress points of the chassis and in other places where they determined that the spot welds needed reinforcement by 40 times compared to the fifth-generation model.
The amount of advanced high-strength steel in the car is also increased. The outgoing model: 21%. The 2017 Elantra: 53%, including hot-stamped grades in the A- and B-pillars.
A consequence is that the new car has a 29.5% stiffer torsional rigidity and 25.3% greater bending strength.
Weâll learn more about the Elantraâwhich is the sixth best-selling car on the planetâearly next year. But clearly, when theyâre looking at a car right down to the bonding, it probably has some impressive ride and handling and NVH characteristics.
