The Toyota i-REAL is a conceptual personal mobility vehicle created as a step towards commercial production in the future. The Toyota i-Real follows in the footsteps of the Toyota PM, i-unit, i-Foot and i-swing. The i-Real uses three wheels (two at the front and one at the back), in low-speed mode, shortening its wheelbase to allow it to maneuver naturally among pedestrians at similar eyesight height without taking up a large amount of space; in high-speed mode the wheelbase lengthens to provide a lower center of gravity and better driving performance. The Toyota i-Real uses a perimeter monitoring system to help keep the driver and those near the vehicle safe. If there is the possibility of a collision the system emits a noise and vibrates, at the same time, the i-Real alerts people around it of its movements through the use of light and sound.
