This book details the origin and history of the Mirage sports cars which the British John Wyer Automotive firm designed and built to contest the various versions of the World Sports Car Championship between 1967 and 1975, funded by the Gulf Oil Corporation. The cars began as developments of the Ford GT40 but soon assumed their own identity. After 1975, the Mirage was no longer in John Wyer hands but the name continued in other hands. This book includes the developmental and race history, with a full list of all events and individual chassis numbers.
