As part of the development of BMW i cars, sustainability targets are established and then pursued with the same vigor as cost, weight or quality objectives. This all-embracing approach is reflected both in the selection of materials and in the construction and manufacturing processes, which differ substantially from conventional manufacturing methods in the automotive industry. The low overall weight of the BMW i8 (3,285 lbs/1,490 kilograms) can be credited primarily to a passenger cell made from CFRP. Although it lends a component at least equal rigidity, this extremely lightweight high-tech material is 50 percent lighter than steel and 30 percent lighter than aluminum. The principle of intelligent lightweight design is applied to all the car's components.
