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. Despite apparent pace, the car was criticized for instability at high speeds and, due to mechanical and electrical failures, did not finish any of the races for which it was entered.
