Why it matters
The Lightweight E-type was Jaguar's factory competition version of the E-type, with aluminium body and hardtop and an all-alloy, fuel-injected 3.8-litre six. Eighteen were planned but only 12 were built, making the originals among the most valuable Jaguars.
How rare is it?
Six separate kinds of rarity – never combined into one number.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionLightweight roadsters built 1963-1964 per Ultimatecarpage; earlier research has 12 factory Lightweights | 101,2 | Factory production | Registry reported |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Following an engineering memo of March 1961, building of the cars began in October 1962 and the first two were ready for Sebring in March 1963. Malcolm Sayer's revised coachwork, developed through the Low-Drag Coupé, was combined with a fuel-injected all-alloy engine. The programme ran into 1964 and stopped at 12 cars; in 2014–15 Jaguar completed the six unused chassis numbers as 'The Missing Six'.

06Reference
Identification guide
How to tell an original from a replica or later conversion.
The chassis number's only Lightweight signifier is its S prefix (e.g. S850667, the 10th of 12). Originals have aluminium body and hardtop and an all-alloy, Lucas fuel-injected 3,781 cc engine, though most survivors now run reproduction alloy blocks. The six 2014–15 'Missing Six' cars are later continuations, not originals.
