The next-generation BMW 7-series will use carbonfibre in its construction, according to R&D chief Klaus Draeger.
After the launch of the i3 and i8 in BMW's new eco sub-brand, the flagship saloon will be the first mainstream BMW model to incorporate the lightweight material, probably in 2015.
Draeger said the new 7-series’ structure would probably feature a mix of materials, with the carbonfibre parts being added to the aluminium and steel used in today’s car. It’s thought the roof, bonnet and bootlid are most likely to be made from carbonfibre.
