The Ford P68, also commonly known as the Ford 3L GT or F3L, is a sports prototype racing car model introduced in March 1968. It was designed by Len Bailey, a Ford research engineer, funded by Ford Europe and built by Alan Mann Racing at Weybridge, Surrey, UK. The first competition appearance of a Ford 3L prototype was at the BOAC 500 race at Brands Hatch in Kent. It delivered a good pace, but was criticized for instability at high speeds. It did not finish any of the races in which it was entered, due to mechanical and electrical failures.

Alan Mann Racing was a British motor racing team organised by Alan Mann, who was a part-time racing driver and team manager. The team ran a substantial part of the Ford works racing effort in Europe from 1964 to 1969, when it ceased operations. It was based in Byfleet, Surrey, near the Brooklands race circuit.
