Toyota's president unveiled a futuristic concept car resembling a giant smartphone to demonstrate how Japan's top automaker is trying to take the lead in technology at the upcoming Tokyo auto show.

Toyota Motor Corp. will also be showing an electric vehicle, set for launch next year, and a tiny version of the hit Prius gas-electric hybrid at the Tokyo Motor Show, which opens to the public this weekend.

The car works like a personal computer and allows drivers to connect with dealers and others with a tap of a touch-panel door, The Associated Press reported
