What is Hyundai’s SuperStructure?Aug 2nd, 2017
The Holy Grail of automotive engineers is to develop the stiffest possible structure at the lowest possible weight. The advantages of doing so are numerous: steering response and handling are improved, along with ride comfort and nuisances like road noise can be mitigated. In the past these goals could only be achieved by very expensive cars.
Now Hyundai has developed a Superstructure for its Elantra family that actually delivers on the goals of automotive engineers. And it’s not through expensive solutions but rather through clever engineering and an interesting partnership that developed the Advanced High Strength Steel that’s the key to the Hyundai Elantra Superstructure. In fact, the Elantra is comprised of 53% Advanced High Strength Steel, one of the largest percentages in the automotive industry.
Hyundai’s partner in developing the Advanced High Strength Steel was Hyundai. You see, while on division of the company build cars, another manufactures steel for 1.2 mm welding wire right up to 400 meter ocean-going container ships – the perfect partners to help develop the required raw materials for the Hyundai Elantra family SuperStructure.
Advanced High Strength Steel is not a phrase that came out of a marketing brain-storming session. In fact, it’s a recognized form of steel with specific grades and compositional requirements. Advance High-Strength Steel is the latest in a series of developments of High Strength Steel, a complex, sophisticated material, with carefully selected chemical compositions and microstructures that result from precisely controlled heating and cooling processes. Specific mechanisms are employed to achieve strength, ductility, toughness, and anti-fatigue properties. In fact, AHSS is twice as strong as the steel from which cars and trucks had been built for years.
Calling this ultra-rigid and lightweight base upon which the whole car rides on the Hyundai SuperStructure, and it’s a safety cage, race car chassis, and luxury car all rolled into one. By having such a rigid chassis enables a number of key improvements to a vehicle’s capabilities.
First, AHSS improves the safety of the Hyundai Elantra by helping to protect occupants inside the vehicle by absorbing harmful energy and redirecting it away from the passenger compartment in the event of a collision. In fact, the SuperStructure based Elantra, when equipped with Autonomous Emergency Braking with Pedestrian Detection, earns a Top Safety Pick+ rating from the U.S. Insurance Institute for Highway Safety – the institute’s highest level of award.
Second, AHSS allows for better handling and steering response because its more rigid structure allows for more precise tuning of suspension components, which in turn improves cornering stability and enhances driver confidence at higher speeds.
And third, a quieter cabin through structural design, AHSS, and the additional application of soundproofing.

At the decommissioned Hearn Generating Station in Toronto, the SuperStructure of the 2017 Hyundai Elantra was put to the ultimate stress test. Seven fully-equipped Hyundai Elantra were stacked upon it, with a combined weight of 12.6 metric tonnes. To provide that these were real cars stacked upon the SuperStructure, as the crane removed the cars one-by-one, they were driven away. Now that’s testing is a very real world sense.
Along with its advanced platform, the 2017 Hyundai Elantra family also comes with a host of safety features including blind spot detection, rear cross traffic alert, lane departure warning, adaptive cruise control, and HID headlights with active cornering.
