The story of the design, development, racing achievements and production career of some of the greatest sports-racing cars of the 1950s, which have since become the stars of the historic racing scene. Powered By Jaguar, the original edition of which was published in 1980, is being brought back into print again in an extensively revised and extended edition of the author's highly regarded book. This is the story, told with Nye's renowned dedication for detail and accuracy, of the cars of four different competition car manufacturers, all of whom used the famous Jaguar XK engine in various forms to ensure their competitiveness on the race tracks of Europe and further afield. Today passionately coveted by owners and by those who crave to be such, they often change hands for vast sums and consequently their provenance is frequently the subject of discussion and argument.After a massive research effort, involving contact with past and present owners throughout the world, the author has managed to find the answer to many of the questions raised, and his extensive record of the lives of these cars over almost half a century is almost certain to become the definitive record, making this important book a 'must have' purchase by anyone associated with the motor racing scene.
