Back in 2013, Nissan unveiled the IDx concept, getting everyone excited about a competitor for the Toyota 86 and a revival of the iconic Datsun 510. But that didn’t happen as of 2017, with Nissan going back and forth with the idea. Four years have passed, and the Japanese firm returned with a new concept car using a similar nameplate. the IMx. But, while it sports a similar badge, the new concept, which made its debut at the 2017 Tokyo Motor Show, is actually entirely different in terms of layout and technology.
