Hyundai Third Generation Platform for New Sonata Dramatically Improves Collision Safety
Hyundai has implemented its third-generation vehicle platform to the new generation Sonata scheduled to go on sale later this month. The new generation of 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 third-generation vehicle platform 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. It has been developed for possible application of Hyundai’s next-generation engine called the Smartstream Powertrain. Noise reduction is also improved with enhanced noise, vibration and harshness (NVH) performance through reinforced sound-absorbing systems in vibration-sensitive parts.
The new platform will improve the market competitiveness of Hyundai’s newest Sonata and future vehicle models with greater flexibility for vehicle development, which dramatically enhances overall design, safety, efficiency, power and driving performance.
