Narrative:

[We were] in cruise; at 6;500 ft; [with] auto-pilot on; 300 degree ground track. I was giving dual cross-country transition instruction to a private pilot in the left seat. I was scanning for traffic and looking for landmarks. My scan went to the 7-8 o'clock position; behind the flying pilots head; and observed a single-engine retractable gear aircraft overtaking and coming directly at us. Estimated the aircraft to be at 50-100 ft away when I saw it. I grabbed the control stick in anticipation of impact. There was not time for evasive action. In the next two seconds; I observed the conflicting aircraft in a straight-level flight attitude; at the 5 o'clock position diverging away at about a 30 degree angle. No radio contact was made with the aircraft.
