Background

The i-unit is an ultra-compact single-seater four-wheeled Toyota concept car. It debuted at the World Expo 2005, held in Aichi Prefecture, Japan. The vehicle is a cross between a microcar, a motorcycle, and a vehicular exoskeleton. The goal of Toyota is to provide a personal mobility, which can be used on roads but also does not hinder interaction with pedestrians. For this the i-unit has two possible setups. First, there is an upright low speed setup, where the rider has a higher position and can have conversations face-to-face with pedestrians and can move among people. This upright position can be transformed while driving to a low position, where the rider sits much lower and more reclined. This high speed setup has a much lower center of gravity and is for driving at higher speeds.
