Hyundai affiliate technology supplier Hyundai Mobis has demonstrated its e-Corner modular steering and propulsion system for EVs in real-world testing, and just released a little more about what the system dynamically enables.
Simply put, it could dramatically change the maneuverability of electrified urban vehicles, driven or not.
The company has garnered attention earlier this year with the system showcased on the Ioniq 5. With steering, braking and propulsion consolidated into a modular unit that can be mounted in all four corners of the vehicle, this has the potential to allow for a new type of skateboarding platform with even more packaging freedom , because the system will turn all four wheels up to 90 degrees individually or separately.
Now the company is testing the technology on public roads adjacent to its test site in South Korea, en route to mass production of the system as early as 2025. And a series of sample scenarios underscores that it goes far beyond the relative gimmick of CrabWalk on the GMC Hummer EV.
Following previous demonstrations from the company, we now see the e-Corner system moving laterally. This is a completely sideways movement of the vehicle, with all four wheels turning 90 degrees. Also featured is what the company calls “zero spin,” turning the front and rear wheels in opposite directions to turn the vehicle in a very small space.
In something called “diagonal driving,” all four wheels turn in the same direction at 45 degrees. There is also a “pivot turn”, which allows the driver to select any point as the center while positioning the wheels to guide the vehicle in a circle around that point.
With this more detailed release, Hyundai Mobis outlines the role of the wheeled motor with the system. That is something that the company has not mentioned or clarified before. And in another view, the company demonstrated the integration of brake-by-wire and steer-by-wire systems, with inclined strut dampers acting as part or all of the vehicle’s suspension.

Hyundai Mobis first revealed the e-Corner in 2021, then translated the idea into the Ioniq 5 on closed circuits this January. It says this is a key mobility technology for electrification and autonomous driving, and shows that such technology has never been mass-produced anywhere in the world.
It’s a similar concept to that used by REE Israel, which has shown several versions of the platform skateboard with modular units across all four wheels. So far, the system has been offered for use in commercial vehicles.

Mobis says that the convergence of steering and braking components with connectivity and electrification, internally, will provide benefits. And from the looks of it, the system managed to pull it off. Now, which Hyundai, Kia or Genesis EV will get to it first?
