The Jaguar XJ220 was first unveiled as a prototype in 1988, and eventually saw production beginning in 1992. Born from a collaboration between Jaguar and automotive specialist Tom Walkinshaw Racing, the XJ220 holds a unique and special place in automotive history. Initially developed by a group of Jaguar employees' spare time, the XJ220 was conceived as a modern version of the successful cars raced by Jaguar at Le Mans in the 50s and 60s. During pre-production, the XJ220 ran into a number of technical and financial hurdles, which greatly altered the final specs of the production car. The most notable of changes was the engine. Originally intended to be a 6.2L V12 engine, production cars were offered instead with a twin turbo V6 engine. While not initially received as Jaguar would have wanted, the XJ220 has grown a strong following and is still Jaguar's only real supercar. This history, coupled with a production run of less than 300 cars, make the XJ220 a collector's dream. A racing version known as the XJ220C was also offered.
