Hyundai Introduces New Platform That's Safer, Sportier, and More Efficient

Hyundai is trickling information about the all-new 2020 Sonata which marks its start of sale (in the U.S., at least) at the end of the month.

After showing off its design and partnership with Bose, Hyundai has now revealed more details about its platform. The 2020 Sonata is the first vehicle to be underpinned by what the Korean carmaker calls its “third-generation vehicle platform.”

The new platform is said to improve the competitiveness of not just the newest Sonata, but all future vehicle models offering greater flexibility for development while enhancing design, safety, efficiency, power, and driving performance.

Thanks to the new platform, the Sonata has reduced weight, while achieving stronger durability. This new platform builds on the former’s core advantages, enabling a stable design with a lower center of gravity. It also enables Hyundai to implement a sportier design to their vehicles moving forward.

The platform also delivers a significant improvement in collision safety through the adoption of a multi-load path structure, ‘Hot Stamping,’ and super-high tensile steel plate.

The sophisticated multi-load path structure increases the energy absorbed by the vehicle in a collision, improving safety with minimization of collision impact into the passenger cabin.

The platform is designed so that the tires move outward during a small overlap collision to maximize customer safety. Such technology inhibits vehicle from spinning and prevents possible secondary collisions.

The extended application of Hot Stamping also prevents deformation of the passenger room, thereby further improving vehicle safety.

The all-new Sonata equipped with the new platform is also expected to improve power and driving performance. Furthermore, it’s been developed to accommodate the next-generation powertrain family called Smartstream Powertrain.

Featuring a system that controls the flow of air, the new platform improves air movement to the engine bay and heat dissipation, which enhances stability in the lower part of the vehicle and minimizes air resistance to deliver excellent efficiency and power performance.

Stability is enhanced by lowering the position of heavy equipment in the platform, which reduces weight and lowers the center of gravity. In addition, it enables agile handling by dramatically expanding lateral stiffness and positioning the steering closer to the wheel center while also providing stable and balanced driving performance by implementing tire-optimization technology. Noise reduction is also improved with enhanced noise, vibration and harshness (NVH) performance through reinforced sound-absorbing systems in vibration-sensitive parts.
