Jaguar XJ13
In 1964, after nearly a decade away from international sports car racing, Jaguar's Competition Department began work on a new race car. Dubbed XJ13, it was conceived with the ultimate goal of competing against the likes of Ford and Ferrari for outright victory at Le Mans. With the green light given for construction in late 1965, XJ13 was completed in 1966 and finally took to the track for testing in the spring of 1967.
