"Index of Performance"

Emulating the LeMans 24 hour race, the two six hour enduros held at Torrey Pines on Oct. 25, 1955 and Jan. 14, 1956 featured an "Index of Performance" award.  This used a handicap formula to theoretically equalize the performance differential between the larger and smaller engined cars.
 
 

"This photo shows one of the nice looking DB Panhards coming out of turn 3 (or 5?), driven by Francois Crouzet. I believe he won the Index of Performance in the January '56 enduro."

(In the 1950s and early 1960s, 750cc. opposed-twin Panhard powered DB (Deutsch- Bonnet) cars like this one dominated the "Index of Performance" contest at LeMans.   TM)

(Crouzet won the "Index of Performance at both the October enduro, where he finished 11th o.a, and in the January event where he placed 14th o.a.  He drove both races "iron man" without a relief driver.   Info from Bob Norton's scans of "MotoRacing" Volume 1 #2  #8)

 
 
"A sorry photo of the Moretti (750cc) owned and driven by John Biehl, a long time early San Diego SCCA driver. He went in too deep going into turn 9 and went off towards the electrical transformers that were protected by a high, and evidently very strong, fence. John was OK but the car was not. He later used the pieces to run an "H mod" car. John is the fellow who brought back the Veritas from Europe that eventually went to La Jollan Walter Roach and is now restored and in Germany."
 
 
"This car ia an Abarth 207A, the very car that Fred Puhn bought some 30 years later and restored. It was one of about 12 of the Fiat engined cars and while they were beautiful to look at, they were underpowered and heavy and no match for the Lotus Mk IX in competition. I took the photo early in the morning as cars were going to tech. You can see the fog.  (I can still smell the eucalyptus and damp haybales.)"
