Is the E2 a pure electric platform? Is it worth buying compared to the Dolphin and Qin?

I've heard it's not the e3.0 platform. The Dolphin you mentioned is on the e3.0 platform, but the Qin Plus EV isn't on the e3.0 platform. It's not exactly a pure electric platform, so technically calling it an oil-to-electric conversion isn't wrong. I'm not sure what platform this generation of e2 is on. I'm actually considering getting one too, since the 400 km range is quite appealing and other models are much pricier. [I want to be alone][I want to be alone][I want to be alone]

I'm also interested in this car and planning to go for it.
