And in addition, BMW uses a slightly unusual technique for building the carbon fiber cloth. It is not woven (as can be seen in the close-up of the carbon fiber cloth) but rather is composed of fiber bundles running in the same direction and sewn together. BMWBLOG believes that this is one of the keys to the quick cycle times in the CFRP press. By keeping the cloth strand oriented in a single direction per layer you decrease the time required to flow resin into the cloth."
Alfa uses hand laid woven carbon fiber, which result in a more high-end product

BMW are smart, why on earth would you put a nice finish on something that will be painted and/or never seen?
