Jaguar E-Type Prototype E2A
Jaguar's second E-Type concept was E2A which, unlike the E1A, was constructed from a steel chassis with an aluminium body. This car was completed as a race car as it was thought by Jaguar at the time it would provide a better testing ground. E2A used a 3-litre version of the XK engine with a Lucas fuel injection system.
After retiring from the LeMans 24 hr the car was shipped to America to be used for racing by Jaguar privateer Briggs Cunningham. In 1961 the car returned to Jaguar in England to be used as a testing mule. Ownership of E2A passed to Roger Woodley (Jaguar's customer competition car manager) who took possession on the basis the car not be used for racing. E2A had been scheduled to be scrapped. Roger's wife Penny Griffiths owned E2A until 2008 when it was offered for sale at Bonham's Quail Auction. It eventually sold for US$4,957,000.
