Shortly after the introduction of the E-Type, Jaguar management wanted to investigate the possibility of building a car more in the spirit of the D-Type racer from which elements of the E-Type’s styling and design were derived. One car was built to test the concept designed as a coupé. Unlike the steel production E-Types, the LDC used lightweight aluminium.
Malcolm Sayer retained the original tub with lighter outer panels riveted and glued to it. The front steel sub frame remained intact, the windshield was given a more pronounced slope, and the rear hatch was welded shut. Rear brake cooling ducts appeared next to the rear windows, and the interior trim was discarded, with only insulation around the transmission tunnel. With the exception of the windscreen, all cockpit glass was perspex. A tuned version of Jaguar’s 3.8-litre engine with a wide-angle cylinder head design tested on the D-Type racers was used.
