BMWs i8 - Aluminum and carbonfiber reinforced plastic oh my!

With its combination of the aluminum Drive module and the CFRP passenger cell (Life module), the BMW i8 is also an excellent example of intelligent lightweight design – one of the guiding principles of the Efficient Dynamics strategy. Use of the lightweight high-tech material CFRP, which also offers excellent crash performance, brings weight savings of 50 percent over steel and around 30 percent over aluminum, with equivalent or improved strength.

This video gives more information about the idea of the intelligent lightweight construction of BMW's i8, to reduce weight on the one hand and to achieve an extremely robust passenger cell on the other.

The weight of that is the same weight of a E90 330i, thats not very sports car weight. But I guess with the battery its still light. Interesting concept though, must be very expensive to have so much carbon fiber
