After a successful decade of racing, Jaguar created a E2A, a new prototype that would lend its development to future racing and production cars. Essentially, E2A became an interim model bridging the gap between the iconic E-Type and the victorious D-Type.
The release of E2A marked Jaguar’s possible intention to continue their motor sports program which ended in 1956. E2A was designed to accommodate the new 1960 sports car regulations which included minimum heights for both the car and windscreen. It was these same restrictions which forced Bizzarrini to raise the windscreen angle on his Ferrari GTO, effectively ruining his initial form.
E2A borrowed much from the D-Type it effectively replaced. The body and chassis formed a single aluminum monocoque. Compared to the long-nose D-Type, E2A was stretched six inches to maintain proper aerodynamics with the large windscreen. Having a high windscreen also necessitated the need for window wipers instead of having the driver just look over the window.
Similar to the D-Type, E2A used an XK-based engine having the same DOHC cylinder head. Different materials were used in the engine, such as an aluminum block and titanium connecting rods. Lucas Fuel Injection was also installed.
As a significant change from the D-Type, E2A used an independent rear suspension with inboard rear brakes. Two ducts just behind the doors provided cooling for the brakes. E2A marks the first Jaguar to have an independent rear suspension.
E2A was initially ordered by Brigs Cunningham for a private assault on LeMans. The car was never given a model designation, but is known for its chassis stamping, E2A. It raced in the 1960 LeMans 24 Hour Race with drivers Dan Gurney and Walt Hansgen. Unfortunately the car retired due to head gasket failure caused by faulty fuel injection.
After LeMans, the windscreen on the car was reduced and a 3.8-litre engine with triple Webers was installed. It continued racing in America for some time until it was shipped back to England for brake testing.
