Jackie Oliver was in charge to show the intentions that Porsche had, when in the practice sessions he managed the best lap time clocked in Le Mans to the present day: 3m13s9/10 at 250.069 km/h average speed, and reaching, during night practice, the barbaric top speed of 396.004 km/h in the Hunnadieres straight, managing to shadow his famous co driver Pedro Rodriguez -star of the race- in the pre-race prognoses.
