After the Kia EV6 launch, the internet brain trust is expecting a larger car (the EV7) and a smaller car (the EV4) to be the next two released. The EV4 is looking to be a mix of the Soul EV and the Kia Seltos. It's been seen in shadowed profile in official Kia photos, and it's been seen in spy photos driven on the road all camo'ed up. But using those photos, a rendering estimating what it looks like has been done:
What people are expecting is the EV4 to be a little more sloped in the back like a Seltos, but nearly identical to the Soul EV in the front, and they also expect it to be based on the E-GMP platform.
Will this replace the Soul EV? Or sit alongside it? With the Leaf on Life support, and the BMW i3 on the way out, that could soon leave only the Model S as being on the market longer than the Soul EV. Unless the EV4 replaces it, of course.
