Hyundai Motor Company and Kia Corporation have introduced an innovative snow chain technology for tires, poised to enhance winter driving safety. This new technology incorporates shape memory alloy modules located within the wheel and tire assembly. These modules can be activated to function as snow chains with a simple electrical signal, offering a seamless transition from regular to winter-ready driving.


Effortless Operation and Safety Enhancement

The main advantage of this technology lies in its ease of use. Traditional snow chains require manual installation, which can be both time-consuming and challenging. In contrast, the new system from Hyundai and Kia utilizes shape memory alloy that can be deployed or retracted at the push of a button. This not only saves time but significantly improves safety, especially during unexpected heavy snowfall.


The Technology Behind the Innovation

The design of this snow chain-integrated tire technology is quite intricate. The tire features radial grooves, similar to slices of a pizza, where modules made of shape memory alloy are inserted. When not in use, the alloy remains compressed inside the wheel, resembling the shape of an 'L'. Upon activation, an electric current causes the alloy to return to its original shape, extending out of the tire in a 'J' shape. This extension makes contact with the road surface, thereby enhancing grip and stability in snowy conditions.

Moreover, this technology offers an additional safety feature. In case of severe tire wear, the visibility of the module alerts drivers to the need for tire replacement, ensuring that tire maintenance is not overlooked.


Future Prospects and Development

Currently holding patent-pending status in South Korea and the U.S., Hyundai Motor and Kia are considering the mass production of this innovative technology. Before this can happen, further technological advancements, durability tests, performance evaluations, and regulatory reviews are necessary. This forward-thinking approach reflects Hyundai and Kia's commitment to leveraging advanced technology for real-world applications, focusing on enhancing the safety and convenience of their vehicles.

  • Ted The automotive period we are in reminds me of the malaise era of the 70s and early 80s. Government emission mandates exceeded the available engineering capabilities of most auto makers (sans Honda). Mileage, performance, and reliability all decreased. It wasn’t until both fuel injection and electronic engine control became available that all three improved again.Seems BEVs are in a similar spot; battery technology needs breakthrough improvement, charging needs to be faster and more ubiquitous. As those things happen, BEVs will make more sense.Agree the aspirational mandates are ahead of the current technology and infrastructure.
  • Golden2husky This was a common topic at work - kids learned how to drive, and now another car is needed. I was amazed at all the excuses made about how their kid must have a new car. Used cars are a "risk" for breakdown, they are not as safe, etc...which is all BS of course. How much difference in safety is there between a new car and the same model that is five years old? Maintained cars don't break down very often. I've driven cars for far, far longer than most and have been towed exactly twice in my entire driving career (about 800,000 miles). While I wouldn't put my daughter into a 15 year old car and let her drive across the country, I would be fine with a 5 year old car that was well cared for. Let's be realistic - new drivers are likely to get into a fender bender - why do that to a new car. I was thrilled to get an 8 year old car for college back in the day even though my folks could afford to buy all of us new cars if they wanted to. If you Want to buy your kid new, go ahead. Just don't freak out when they come home with a fresh dent.
  • CanadaCraig Can you eventually go to prison for driving without a licence in the US?
  • CanadaCraig To hell with the UAW.
  • CanadaCraig First I'll answer the question. YES. Toyota, Mazda and Subaru are doing the right thing. That said... If only those pushing for an all EV world would care as much about the 1 BILLION earthlings that make less than $1 a day.
