Renault will show four new electric vehicle concepts at next week’s Frankfurt Motor Show, previewing what is expected to become a new Zero Emission product range from the French manufacturer. No details of the four cars have been made available, but sketches of the four vehicles have been released showing them from above, and the most exciting concept appears to be a very small and narrow single seat four-wheeled personal transport concept (pictured). Check out the from-above images of all four vehicles inside.
