The new BMW M6 Gran Coupe combines elegant design with luxurious appearance, complemented perfectly by the contoured roof made with Hexcel’s PrimeTex® woven carbon fabric.
PrimeTex® is Hexcel’s patented technology for carbon fabrics, in which the fibres are spread in both the warp and weft direction, increasing the closure factor by 5-8% compared to conventional weaving processes. This results in a highly uniform fabric ideal for very lightweight structures requiring aesthetic appeal combined with high mechanical performance and very low porosity.
BMW claims on their website that the contoured roof effectively lowers the weight and centre of gravity of the M6 Gran Coupe for even better driving characteristics. Read more at this link (scroll down to Carbon Roof section):
