Yes the 919 was just that. De-restricted LMP1 car. 1200bhp and 50% more aero than they can run in WEC.
Apparently the 919 was set to go to Pikes Peak and take the record there as well. But Daddy stepped in and took the ball away. More than likely due to VW's need to rapidly rebuild its US image after the issues it's had over there for the last couple of years...
