The Jaguar E-Type (UK) or XK-E (US) is a British automobile manufactured by Jaguar between 1961 and 1974. Its combination of good looks, high performance, and competitive pricing established the marque as an icon of 1960s motoring. A great success for Jaguar, over seventy thousand E-Types were sold during its lifespan.
In March 2008, the Jaguar E-Type ranked first in Daily Telegraph list of the "100 most beautiful cars" of all time. In 2004, Sports Car International magazine placed the E-Type at number one on their list of Top Sports Cars of the 1960s.
The E-Type was initially designed and shown to the public as a grand tourer in two-seater coupé form (FHC or Fixed Head Coupé) and as convertible (OTS or Open Two Seater). The 2+2 version with a lengthened wheelbase was released several years later.
On its release Enzo Ferrari called it "The most beautiful car ever made".
The model was made in three distinct versions which are now generally referred to as "Series 1", "Series 2" and "Series 3". A transitional series between Series 1 and Series 2 is known unofficially as "Series 1½".
In addition, several limited-edition variants were produced:
• The "'Lightweight' E-Type" which was apparently intended as a sort of follow-up to the D-Type. Jaguar planned to produce 18 units but ultimately only a dozen were reportedly built. Of those, one is known to have been destroyed and two others have been converted to coupé form. These are exceedingly rare and sought after by collectors.
• The "Low Drag Coupé" was a one-off technical exercise which was ultimately sold to a Jaguar racing driver. It is presently believed to be part of the private collection of the current Viscount Cowdray.
After their success at LeMans 24 hr through the 1950s Jaguars defunct racing department were given the brief to use D-Type style construction to build a road going sports car, replacing the XK150.
It is suspected that the first prototype (E1A) was given the code based on: (E): The proposed production name E-Type (1): First Prototype (A): Aluminium construction (Production models used steel bodies)
The car featured a monocoque design, Jaguar's fully independent rear suspension and the well proved "XK" engine.
The car was used solely for factory testings and was never formally released to the public. The car was eventually scrapped by the factory
Jaguar's second E-Type concept was E2A which unlike E1A was constructed from a steel chassis and used a aluminium body. This car was completed as a race car as it was thought by Jaguar at the time it would provide a better testing ground.
E2A used a 3 litre version of the XK engine with a Lucas fuel injection system.
After retiring from the LeMans 24 hr the car was shipped to America to be used for racing by Jaguar privateer Briggs Cunningham.
In 1961 the car returned to Jaguar in England to be used as a testing mule.
Ownership of E2A passed to Roger Woodley (Jaguars customer competition car manager) who took possession on the basis the car not be used for racing. E2A had been scheduled to be scrapped.
Roger's wife Penny Griffiths owned E2A until 2008 when it was offered for sale at Bonham's Quail Auction. Sale price was US$4.5 million

The Series 1 was introduced, initially for export only, in March 1961. The domestic market launch came four months later in July 1961. The cars at this time used the triple SU carburetted 3.8 litre 6-cylinder Jaguar XK6 engine from the XK150S. The first 500 cars built had flat floors and external hood (bonnet) latches. These cars are rare and more valuable. After that, the floors were dished to provide more leg room and the twin hood latches moved to inside the car. The 3.8 litre engine was increased to 4.2 litres in October 1964.
All E-Types featured independent coil spring rear suspension with torsion bar front ends, and four wheel disc brakes, in-board at the rear, all were power-assisted. Jaguar was one of the first auto manufacturers to equip cars with disc brakes as standard from the XK150 in 1958. The Series 1 can be recognised by glass covered headlights (up to 1967), small "mouth" opening at the front, signal lights and tail-lights above bumpers and exhaust tips under the licence plate in the rear.
3.8 litre cars have leather-upholstered bucket seats, an aluminium-trimmed centre instrument panel and console (changed to vinyl and leather in 1963), and a Moss 4-speed gearbox that lacks synchromesh for 1st gear ("Moss box"). 4.2 litre cars have more comfortable seats, improved brakes and electrical systems, and an all-synchromesh 4-speed gearbox. 4.2 litre cars also have a badge on the boot proclaiming "Jaguar 4.2 Litre E-Type" (3.8 cars have a simple "Jaguar" badge). Optional extras included chrome spoked wheels and a detachable hard top for the OTS.
An original E-Type hard top is very rare, and finding one intact with all the chrome, not to mention original paint in decent condition, is rather difficult. For those who want a hardtop and aren't fussy over whether or not it is an original from Jaguar, several third parties have recreated the hardtop to almost exact specifications. The cost ranges anywhere from double to triple the cost of a canvas/vinyl soft top.
A 2+2 version of the coupé was added in 1966. The 2+2 offered the option of an automatic transmission. The body is 9 in (229 mm) longer and the roof angles are different with a more vertical windscreen. The roadster remained a strict two-seater.
There was a transitional series of cars built in 1967-68, unofficially called "Series 1½", which are externally similar to Series 1 cars. Due to American pressure the new features were open headlights, different switches, and some de-tuning (with a downgrade of twin Zenith-Stromberg carbs from the original triple SU carbs) for US models. Some Series 1½ cars also have twin cooling fans and adjustable seat backs. Series 2 features were gradually introduced into the Series 1, creating the unofficial Series 1½ cars, but always with the Series 1 body style.
Less widely known, there was also right at the end of Series 1 production and prior to the transitional "Series 1½" referred to above, a very small number of Series 1 cars produced with open headlights. These are sometimes referred to as "Series 1¼" cars. Production dates on these machines vary but in right hand drive form production has been verified as late as March 1968. It is thought that the low number of these cars produced relative to the other Series make them amongst the rarest of all production E Types.
An open 3.8 litre car, actually the first such production car to be completed, was tested by the British magazine The Motor in 1961 and had a top speed of 149.1 mph (240.0 km/h) and could accelerate from 0-60 mph (97 km/h) in 7.1 seconds. A fuel consumption of 21.3 miles per imperial gallon (13.3 L/100 km; 17.7 mpg-US) was recorded. The test car cost £2097 including taxes.

Open headlights without glass covers, a wrap-around rear bumper, re-positioned and larger front indicators and taillights below the bumpers, better cooling aided by an enlarged "mouth" and twin electric fans, and uprated brakes are hallmarks of Series 2 cars. De-tuned in US, but still with triple SUs in the UK, the engine is easily identified visually by the change from smooth polished cam covers to a more industrial 'ribbed' appearance. Late Series 1½ cars also had ribbed cam covers. The interior and dashboard were also redesigned, with rocker switches that met U.S health and safety regulations being substituted for toggle switches. The dashboard switches also lost their symmetrical layout. New seats were fitted, which purists claim lacked the style of the originals but were certainly more comfortable. Air conditioning and power steering were available as factory options.
Production according to Graham is 13,490 of all types.

A new 5.3 L 12-cylinder Jaguar V12 engine was introduced, with uprated brakes and standard power steering. The short wheelbase FHC body style was discontinued and the V12 was available only as a convertible and 2+2 coupé. The convertible used the longer-wheelbase 2+2 floorplan. It is easily identifiable by the large cross-slatted front grille, flared wheel arches and a badge on the rear that proclaims it to be a V12. There were also a very limited number of 4.2 litre six-cylinder Series 3 E-Types built. These were featured in the initial sales literature. It is believed these are the rarest of all E-Types of any remaining.
In 2008 a British classic car enthusiast assembled what is surely the last ever E-Type from parts bought from the end-of-production surplus in 1974.
Graham lists production at 15,290.

Two limited production E-Type variants were made as test beds, the Low Drag Coupe and Lightweight E-Type, both of which were raced:
Low Drag Coupé (1962)
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 as its monocoque design could only be made rigid enough for racing by using the "stressed skin" principle. Previous Jaguar racers were built as open-top cars because they were based on ladder frame designs with independent chassis and bodies. Unlike the steel production E-Types the LDC used lightweight aluminium. 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 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 plexi. 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. Air management became a major problem and, although much sexier looking and certainly faster than a production E-Type, the car was never competitive: the faster it went, the more it wanted to do what its design dictated: take off.
The one and only test bed car was completed in summer of 1962 but was sold a year later to Jaguar racing driver Dick Protheroe who raced it extensively and eventually sold it. Since then it has passed through the hands of several collectors on both sides of the Atlantic and now is believed to reside in the private collection of the current Viscount Cowdray.
Lightweight E-Type (1963-1964)
In some ways, this was an evolution of the Low Drag Coupé. It made extensive use of aluminium alloy in the body panels and other components. However, with at least one exception, it remained an open-top car in the spirit of the D-Type to which this car is a more direct successor than the production E-Type which is more of a GT than a sports car. The cars used a tuned version of the production 3.8 litre Jaguar engine with 300 bhp (224 kW) output rather than the 265 bhp (198 kW) produced by the "ordinary" version. At least one car is known to have been fitted with fuel-injection.
Bob Jane won the 1963 Australian GT Championship at the wheel of an E-Type.
The Jaguar E-Type was very successful in SCCA Production sports car racing with Group44 and Bob Tullius taking the B-Production championship with a Series-3 V12 racer in 1975. A few years later, Gran-Turismo Jaguar from Cleveland Ohio campaigned a 4.2 L 6 cylinder FHC racer in SCCA production series and in 1980, won the National Championship in the SCCA C-Production Class defeating a fully funded factory Nissan Z-car team with Paul Newman.
