Not only that, but the headline's gone off the path quite a way. While the I3's front wheels are not driven by an axle, they do rotate on a stub axle, which I guess is technically an axle. It's really just a short metal stick (an accurately manufactured one) that locates the center of the wheel bearings. They're also using the stock steering knuckle, which is the part that actually turns. What they've invented is moving the tie rod connection closer to the stock center of rotation with hacked-up bolt-on bits. That's beer engineer level stuff.
