Penned at the company's Californian design studios with technology input from Toyota's Innovation Hub in San Francisco, the Concept-i was reportedly designed from the inside out, and will reportedly begin on-road tests "within the next few years in Japan".
The car's design is said to exemplify the philosophy of "kinetic warmth", and features seating for four people, who enter and exit via two large flip-up doors.
At the car's core is an AI system known as Yui that's able to learn the driver's schedule and travel patterns, as well as discern his or her emotional state.
Yui is able to automatically increase or decrease the amount of automated driving assistance provided depending on the conditions and the amount of driver engagement.
The AI system is able to communicate via sound, touch, and lights on the dashboard and throughout the interior. When in driving mode, expansive head-up displays provide the driver with all the necessary navigation and car status information.
The bonnet, doors and tailgate of the Concept-i are able to display messages for the benefit of both passengers and other road users. In self-driving mode, the Concept-i's bonnet lights up with the blue "Automated" message.
The tailgate display is a little more dynamic, and can indicate a lane changing manoeuvre, warn other cars about upcoming dangers, or thank another driver for letting you in.
