BMW i3 & CFRP, Perfect Together

One of the main goals BMW had with the development of the Megacity car now known as the i3, was to reduce the weight as much as possible while providing a strong, safe passenger cell. The extensive use of carbon fiber reinforced plastics or CFRP, has allowed them to do just that. While the use of CFRP isn't a new idea in the automotive industry, using it as extensively as BMW is on the i3 is groundbreaking. It's been written that by using CFRP as extensively as they are, it has cut the weight of the vehicle by as much as 700lbs. This will allow BMW to use less of the expensive batteries and still hit their target 100 mile range. That will also reduce cost and further reduce weight since the batteries are also heavy. The above video talks about how BMW is using CFRP and references the i3 a couple times.
