In a recent interview, BMW's head of research and development revealed the next-generation 7-Series will feature carbon fiber construction.

Speaking with Autocar, Klaus Draeger said the car would likely feature carbon fiber, aluminum and steel. This means we can expect the lightweight material to be used in the roof, hood and trunk lid.

These changes could enable the 2015 7-Series to be significantly lighter than the current model, so expect improved fuel efficiency and reduced emissions.
