|Jaguar has announced the new handcrafted Lightweight E-type, a recreational variant from the Heritage division of Jaguar Land Rover. There are only six lightweight E-types available, each with a unique chassis number.|
At a glance, the Jaguar Lightweight E-type which is slated for debut at the Pebble Beach’s Concours d’Elegance features an aluminium bodyshell all around; the doors, trunklid, hardtop and bonnet. The aluminium bodyshell replaced the steel of the production E-type in the quest to shed weight, some 114 kilograms (250lb) were saved compared with the standard version.
The Jaguar Lightweight E-type Heritage is a step-up of the 1964 E-type
Based on the 1964 version, the new lightweight E-type is slated to be sold as period competition vehicles, and even adheres to FIA homologation for historic motorsport purposes. The <300 bhp powerplant developed for the Lightweight E-type is based on the 3,868cc engine which, in the D-type, had won Le Mans in 1957. Torque values are 379 Nm (280lb ft) at 4500 rpm. Needless to say, the lightweight is endowed with rapid acceleration from comparatively low engine revs. The power is transferred to the road via a lightweight, low inertia flywheel, a single-plate clutch and a Jaguar close-ratio, manual four-speed all-synchromesh gearbox as used by the Lightweight E-type in period. A variety of final drive ratios are available, all with the Powr-Lok limited-slip differential, but a 3.31:1 ratio is supplied as standard.
A similar big valve ‘wide angle’ cylinder head is used, but in place of the D-type’s cast iron block, Jaguar introduced an aluminium block for the Lightweight E-type which substantially reduced the amount of weight over the front wheels. This is also featured in the present-day car, with pressed-in steel liners.
Another major feature transferred from the D-type is the dry sump lubrication system. This uses a scavenge pump to collect oil from the sump and return it to a separate oil tank in the underbonnet area. The compression ratio is 10:1 and today’s car is supplied with three 45DCO3 Weber carburettors. These were homologated by Jaguar for the Lightweight E-type in addition to a Lucas mechanical fuel injection system, which is being offered to customers as a cost-option. Additionally, the exhaust manifold is a steel fabrication and leads the exhaust gasses into twin pipes which take them through a center silencer box to the rear of the car, where the exhaust system ends in twin polished tail pipes. Other highlights include a 12 volt negative earth electrical system, a inertia-type starter motor, aluminium alloyed water & oil radiators and a mesh-filled fuel tank.
The Jaguar Lightweight E-type is offered in six ‘heritage’ paint colors: Carmine red, opalescent grey metallic, silver metallic, opalescent blue metallic, British racing green, Old English white. However, various color and trim alternatives are available, as each car is built to the personal specification of each individual customer.
