The 1968 24 Hours of Le Mans was the
36th Grand Prix of Endurance, and took place on 28 and 29 September 1968
on the Circuit de la Sarthe, in Le Mans, France.
Originally scheduled for the weekend
of 15 and 16 June, the race had to be delayed until September due to
protests, strikes, and civil unrest in France during the summer of 1968.
The rescheduled race increased the chances of the Group 6 Prototypes
against the Group 4 Sports cars, as the new Prototype cars had matured
during the season. It also increased the amount of darkness that drivers
would be racing in compared to June, by about three hours: a total of 11
hours. Its new date made it the tenth and final round of the 1968 World
Sportscar Championship of a tense and close championship between Ford
and Porsche.
The winners were Pedro Rodriguez and
Lucien Bianchi, in the J.W. Automotive Gulf-Oil Ford GT40. Despite
Porsche finishing second and third, the victory was enough to give Ford
the manufacturer's title.
There were also two major accidents
during the race ending the racing careers of Willy Mairesse and Mauro
Bianchi (Lucien's younger brother), who both suffered severe burns in
the crashes.
Straight after the 1967 race, the CSI
(Commission Sportive Internationale - the FIA’s regulatory body)
convened to discuss ways to limit the increasingly dangerous speeds in
Sports car racing, mindful of what led to the 1955 disaster. It was
decided to impose a 3-litre (120-litre fuel tank) on Group 6 Prototypes
and a 5-litre limit (160-litre fuel tank) on Group 4 Sports. There
remained no engine limit on the Group 3 GTs. It effectively banned the
big-block Fords and Chaparral, as well as the big Ferraris and the new
Mirage and Lola-Aston Martin and marked the end of an era. The theory
was that manufacturers would turn to the use of 3-litre Formula One
engines to save development costs.
However, it was the immediate
implementation in the next year that caused much unrest with the
companies. The CSI cited ‘safety concerns’ justifying the rapid action.
Enzo Ferrari cancelled his Prototype program. He was not alone in
believing a 5-litre Sports car would outperform a 3-litre Prototype, and
that only the big manufacturers would be able to make the minimum 50
big-engined cars to get Group 4 homologation.
Because the race was rescheduled and
the longer period of darkness, the Automobile Club de l'Ouest (ACO)
permitted one battery change. With high speed being such a talking
point, Ford volunteered to sponsor a major road realignment on the main
straight, installing a chicane just before the pitlane. The changes
added at least 10 seconds to a lap, as well as causing greater wear on
tyres and brakes. Although the track had been widened and safety
features of the track improved in the aftermath of the 1955 disaster,
this was the first significant layout-change to the circuit since 1932.
Diverting the racing away from the pits also significantly increased the
safety of the pit-crews. Finally, in line with the global racing trend,
commercial advertising was now allowed on cars.
