During the '70s the Hockenheimring was a frequent venue for the European Formula II Championship. The Formula II series was generally viewed as the last step on the climb to a Formula I drive. The track was an odd layout and spectators had limited viewing opportunities. Most of the circuit was the long run through the forest out to the Ostkurve and then back to the stadium. The Sachs Curve was a 180 degree turn that afforded reasonably close view of the action and passing.
Sachs Curve captures the essence of Formula II in the era. The ground-effect era when aerodynamics played supreme was still in the future. In this long-gone time spectators could cheer a group of cars closely grouped up and drivers fighting for position.
