Toyota unveiled 15 futuristic concept cars at the Tokyo motor show to promote environmentally friendlier vehicles and technology. One of these 15 cars is called the Concept-i, which appears sleek and silent like the other vehicles, but with a difference. The car's exterior communicates with its driver and passengers, making "empathetic communication possible on a completely new level." Toyota has released 15 concept cars that it says could become production models shortly. They include a full-size electric sedan, a hybrid minivan, a 4-door sports car, and a pickup truck with an extended cab and cargo bed that can be separated into two sections. The company also announced plans to add hybrid versions of its popular Camry and Prius sedans and its RAV4 SUV to its lineup.
