Above: This is the track, with full facilities; it would use a small part of the original Nurburgring - the section from Hatzenbach (running backwards) then straight down towards the new Nordschlief turn, which is in approximately the same place if not a little further left, than the current final turn.
Above: This is the circuit complete with corner names
Above: This is the overlay of the two circuits.
