While the 2001 chassis modifications were subtle, there was one announcement post-Le Mans that was very significant.  Audi revealed that their 2001 Le Mans winning engine was utilizing direct fuel injection.  This system injects fuel directly into each cylinder and offers benefits in increased power as well as decreased fuel consumption (on the order of 8% according to Audi).  This makes the Audi R8 the first race car to incorporate this technology.  The fact they won Le Mans with it makes it even more significant.
