About Jaguar E1A
Inspired by the company's success at the Le Mans 24 hr through the 1950s, Jaguar's racing department was given the brief to use D-Type style construction to build a road-going sports car, replacing the XK150. The first prototype known as E1A stood for E-Type car number 1 and the A reffed to it’s aluminum monocoque body. The E1A, featured a monocoque design designed in 1957 by William Heynes Technical Director and Chief Engineer, Jaguar's fully independent rear suspension and the well proven "XK" engine. The car was used solely for factory testing and was never formally released to the public.
