Why it matters

Chassis P/1075 won the Le Mans 24 Hours in 1968 and again in 1969 for John Wyer's Gulf team, and only one other chassis has won Le Mans twice. That makes it among the most important GT40s.

History

John Wyer Automotive Engineering (JWAE), backed by Gulf Oil, took over Ford's GT40 operation at Slough after 1966. After the FIA imposed a three-litre limit on Group 6 prototypes from 1968, JWAE turned to the Mk I GT40, which was already homologated in Group 4 with up to five litres. P/1075 was one of a small number of upgraded Mk Is built for 1968 and may have been built on a leftover Mirage M1 tub.

In 1968 it won at Watkins Glen and at Le Mans, where Pedro Rodriguez and Lucien Bianchi finished five laps ahead of the second-place Porsche 907. In 1969 Jacky Ickx and Jackie Oliver won the Sebring 12 Hours and then Le Mans with it. Gulf kept the car for promotional duty, lent it to the Indianapolis Motor Speedway Museum in 1976 and sold it in 1984 to dealer Harley Cluxton in Arizona, who kept it until the 1990s.

The two sources disagree on its other 1968 results: Supercar Nostalgia credits it with the Monza win, while the Supercars.net results list shows a Monza retirement and credits Brands Hatch and Spa instead.

06Reference

Identification guide

How to tell an original from a replica or later conversion.

Identification rests on the chassis number P/1075 and its documented race history: Le Mans 1968 (number 9, Rodriguez/Bianchi) and Le Mans 1969 (number 6, Ickx/Oliver). The Supercar Nostalgia page notes it may have used a leftover Mirage M1 tub, a point to check in the car's documentation. The Gulf livery is not unique to this car, since other JWAE chassis wore it.
