A carbon driveshaft actually has a couple different benefits other than being able to handle more torque when compared to a steel driveshaft. One major benefit to a carbon driveshaft is that it absorbs vibrations better than a steel or even an aluminum driveshaft. For a car like the M3/M4, it was 100% a 'because race car' feature. BMW could have gotten away with a steel or even an aluminum driveshaft from the very beginning and nobody would have noticed any kind of difference. Weight savings from a carbon driveshaft and an aluminum driveshaft isn't massive.
