Toyota has partnered with European industrial designer Jean-Marie Massaud to create the Me.We, a concept it describes as four cars in one.
The carmaker says the driving goal behind the concept was to embrace individual freedom (Me), and to demonstrate "responsibility to society" (We).
In simple terms, the Me.We represents a "no frills" response to the environmental effects of mass production, focusing on recyclable materials and renewable resources.
The Yaris-sized Me.We's construction includes a tubular aluminium chassis and expanded polypropylene panels, the latter familiar as a packaging material.
The body panels weigh just 14kg - a saving of around 180kg compared with the use of steel.
To boost the use of renewable materials and to keep weight down to just 750kg, the team also used strong bamboo to make not only the dashboard, but also the entire floor.
Toyota says the polypropylene panels are interchangeable, allowing owners to easily change the colour of their Me.We. There's also removeable rear seats, which can be used outside of the car as handy picnic seats.
Toyota says the Me.We can be configured as a small city car, off-roader, ute and convertible, making it adaptable to a variety of lifestyles.
"Our lives and needs require more adaptability, simplicity and lightness," Massaud said. "The car of today should be seen as a personal mobility solution that can deliver more."
Power for the five-seat Me.We is provided by the same electric system that drives the recent i-Road concept, offering two- and all-wheel driving modes.
Toyota plans to display the Me.We at its Le Rendez-vous Toyota experience center on the Champs Elysées in Paris, but a production debut is not planned.
