Tetra represents the blend of a foldable uni-personal vehicle and an executive class car. It is designed as a mobility solution for people living in residential areas that use a 4 door car as a daily way to go to the city.
A lot of cities like Barcelona present the same issue: most of the surrounding residential areas are poorly or non connected to the city and workers are forced to use the car as a way to move, creating huge traffic jams at rush hours. Moreover the city isn't prepared to absorb such amount of cars that are not registered and available parking space isn't enough. This creates huge traffic problems that turn into tons of air pollution every year.
Tetra is born to solve space and pollution problems in the 21st century city, with elegance, agility and comfort.
