1968 Ford GT40 Mark I ‘Gulf Oil’

In 1967, the CSI changed regulations such that a three-litre capacity limit was imposed on prototypes which eliminated the 427 Fords. Fortunately, J. W. Automotive Engineering Ltd. (JW) & Gulf Oil, under the capable direction of John Wyer, saw more potential in the GT40 platform as a Group 4 sports car and extended their GT40 program.

JW modified two of their lightweight GT40s from the 1967 season known as the Mirage M1s. These kept their lightweight chassis, but used carbon-fiber reinforced bodywork that outwardly mimicked the original GT40 Mk I.

In 1968 competition came from the Porsche 908 which was the first prototype built for the 3-liter Group 6.

The result of the 1968 was resounding success at the 24 Hours of Le Mans with Pedro Rodriguez and Lucien Bianchi having a clear lead over the Porsches. The season began slowly for JW, losing at Sebring and Daytona before taking their first win at the BOAC International 500 at Brands Hatch. Later victories included the Grand Prix de Spa, 21st Annual Watkins Glen Sports Car Road Race and the 1000 km di Monza.

A late Le Mans was run in August and was the decider for the International Championship for Makes. With the GT40 win, Ford was again at the top. The winning car, chassis P/1075 repeated history in 1969 by winning Le Mans again.

Featured above is Ford GT40 Chassis P/1075. This is the most important GT40 as it won both the 1968 and 1969 Le Mans 24 hour races. Only 2 cars in history have ever achieved that goal.
