Seoul, South Korea - Hyundai Motor Company and Kia Corporation have unveiled a new electric vehicle (EV) drive system called "Uni Wheel." 

The system, unveiled at an event in Seoul, South Korea, features the placement of crucial drivetrain components inside the wheel hub. 

This design choice aims to increase the interior space of EVs significantly.

Why It Matters:

Introducing the "Uni Wheel" system represents a potential shift in EV design, focusing on maximizing interior space.

This technology could influence the future design of EVs, emphasizing adaptable and spacious interiors.

The Key Points

  • The Uni Wheel system integrates the reduction gear and a compact electric motor into the wheel, eliminating the need for traditional driveshafts and other significant mechanical components.
  • The technology includes a unique gear configuration and a powered multi-link suspension that allows each wheel to move independently. This maintains drivetrain efficiency and provides a smoother ride over uneven terrain.
  • The system's adaptability makes it suitable for various vehicle sizes and types, extending its potential use to smaller mobility devices such as wheelchairs and robots.

What They Say:

Jongsool Park, a senior executive at Hyundai's R&D center, commented on the system's ability to optimize space and influence future vehicle designs.

Industry analysts highlight the system's potential to reshape the design and functionality of future EVs.

What Comes Next:

Hyundai and Kia are actively working to refine the Uni Wheel system.

Their goal is to improve its efficiency and durability and to explore its application in various types of vehicles, including passenger cars, commercial vehicles, and other mobility devices. 

According to industry observers, if the Uni Wheel system achieves its expected potential, it could set new standards in electric mobility, especially regarding versatility and space. 

This development could give Hyundai and Kia a competitive edge in various sectors, especially where customization and space optimization is essential, such as ride-sharing and last-mile delivery services.
