The 8 Series is built on BMW’s CLAR architecture and is lighter, sharper and more dynamic than the 8 Series Coupe it replaces. A lot of that has to do with its Carbon Core technology, which gives the 8 Series some carbonfiber in its chassis structure, keeping the weight down while also increasing structural rigidity. That will help it be sharper and more agile when the roads get twisty.
