The i3 is built by BMW. The "i" line is BMW's line of alternative energy vehicles, with the i3 being a small electric hatchback. While electic motors and batteries tend to be quite heavy, the engineers at BMW managed to keep the vehicle's weight relatively low by using carbon fiber in the cabin and a lot of aluminum in the chassis.
An "ECO PRO" mode would use various power saving tricks to extend the range by over 20%.
The production of the i3 began in 2012 and concluded in 2022.
