For many enthusiasts the Jaguar D-Type and E-Type are household names. The former is the three times Le Mans winner, while the latter is one of the sexiest road cars ever constructed. Few though realize just how closely these two seemingly completely different machines are related. The similarities are not immediately visible, but the semi-monocoque chassis used in both cars is virtually identical in design. During the transformation of the D-Type racing car into the E-Type production car, Jaguar built various prototypes. The most famous and sole survivor is dubbed E2A. Underlining its competition heritage, E2A was extensively raced in 1960 by the likes of Jack Brabham, Dan Gurney, Walt Hansgen and Bruce McLaren. After its testing and racing duties, the unique machine was destined to be scrapped like all other Jaguar pre-production prototypes. Fortunately the current owner stepped in and managed to pry the fabulous machine away from Jaguar before it was destroyed. This Friday and for the first time ever the ‘missing link’ between the D-Type and E-Type will be offered to the public. Auctioneer Bonhams will offer the very original machine during their Quail Lodge auction in Monterey, California. Considered one of the most important Jaguar’s in existence, it is expected to sell for over $7 million, which would mean a new record for Jaguar motor car.
