New Hyundai Sonata based on third-generation vehicle platform

Hyundai Motor announced that the new generation Sonata, scheduled to go on sale later this month, is based on the new third-generation vehicle platform. Hyundai says that the new platform will improve the market competitiveness of Hyundai’s newest Sonata and future vehicle models with greater flexibility for vehicle development—which enhances overall design, safety, efficiency, power and driving performance.

The new generation Sonata offers reduced weight and improved fuel efficiency while also achieving stronger durability with the new platform. The platform builds on the former platform’s core advantages, enabling a stable design with a lower center of gravity. The third-generation platform also allows Hyundai to implement sporty and stylish design elements to the new Sonata.

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 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.

Smartstream Powertrain. The all-new Sonata equipped with the new platform is also expected to improve power and driving performance. It has been developed for possible application of Hyundai’s next-generation engine called the Smartstream Powertrain. (Earlier post.)

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 improved 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.

Through implementation of the third-generation platform, the new generation Sonata is expected to provide world-class value in overall vehicle performance. Starting with the new Sonata model, Hyundai will gradually expand the use of new platform in order to provide joy of driving and comfort to the customers.
