Quoting Smithsonian National Air and Space Museum | Lockheed P-38J-ten-LO Lightning :


In the P-38 Lockheed engineer Clarence &quotKelly&quot Johnson and his team of designers developed a single of the most successful twin-engine fighters ever flown by any nation. From 1942 to 1945, U. S. Army Air Forces pilots flew P-38s more than Europe, the Mediterranean, and the Pacific, and from the frozen Aleutian Islands to the sun-baked deserts of North Africa. Lightning pilots in the Pacific theater downed a lot more Japanese aircraft than pilots flying any other Allied warplane.


Maj. Richard I. Bong, America’s leading fighter ace, flew this P-38J-10-LO on April 16, 1945, at Wright Field, Ohio, to evaluate an experimental technique of interconnecting the movement of the throttle and propeller handle levers. Nonetheless, his appropriate engine exploded in flight before he could conduct the experiment.

Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress &quotEnola Gay&quot:


Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Globe War II and the first bomber to home its crew in pressurized compartments. Even though developed to fight in the European theater, the B-29 discovered its niche on the other side of the globe. In the Pacific, B-29s delivered a assortment of aerial weapons: standard bombs, incendiary bombs, mines, and two nuclear weapons.


On August 6, 1945, this Martin-constructed B-29-45-MO dropped the 1st atomic weapon employed in combat on Hiroshima, Japan. 3 days later, Bockscar (on show at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Wonderful Artiste, flew as an observation aircraft on both missions.

Electronics Prototyping Methods And Benefits


Electronics Prototyping Methods And Rewards

A prototype is the first ready example for an usually larger project. Prototypes are utilised as an crucial component of a design and style method, as they enable the designers to try out theories and test attainable alternative models just before final style decisions are produced. New designs may be problematic or not performing as anticipated.


A frequent design and style approach is employing a series of prototypes to construct and test as the final style requires type. Specialists getting skills in the manufacturing techniques are utilised to interrelate with theoretical designers, ensuring the practicality of the style. Moreover, prototypes act as a preliminary but detailed instance for relevant persons so that they can greater understand the scope and targets of a style project.


Electronic prototypes are sometimes constructed on a breadboard and show no resemblance to the size or appearance of the final solution. These prototypes aid to recognize which choices will operate and show areas exactly where much more study and testing are needed. They enable interaction with the finish user, generating confident specifications are being met.


The solder-less breadboard is a widespread technique that works effectively with ICs and is fast and straightforward to create and to make modifications. Its use is limited to smaller circuits and high capacitance values can be experienced among the rows. With Wire Wrap it is feasible to make complex circuits speedily in a compact style. Wire is wrapped tightly about the square pins of particular IC sockets. The resulting circuit is trustworthy and affordable but only tends to make a excellent connection to a square lead. Elements like resistors and capacitors are soldered to a header that will match an IC socket or to individual wire pins.


Perforated board is another approach. Leads are just twisted and soldered with each other and connecting wires are run wherever necessary. This is a dependable procedure and can handle any size of component. It does not function nicely with ICs and is slow to make, requiring talent to construct.


A PCB with a pattern of holes and connections is accessible and this is easier than making use of a plain perforated board, particularly when working with ICs. A plain board with a copper surface can also be employed. Identified as a Dead Bug, ICs are glued to the board upside down with the leads sticking out, enabling other elements to be soldered to them. This can result in a higher performance circuit that is economical and dependable. These do need a higher level of ability at soldering and can take time to create.


Components are surface mounted in most modern designs. This is an easier board layout and results in a much more compact board. Surface mount styles can be laid out and designed utilizing specialist application. They are very reputable, but it is hard to make adjustments. Acquiring a board fabricated can take time and be pricey but after the style is set it can be reproduced very easily and cheaply.


An benefit to building an electronics prototype is that a theoretical design and style becomes obtainable to verify for right function and gives a physical platform for tweaking and debugging. Due to the fact these goods are built making use of strategies like wire wrap and bread boarding the prototype has small resemblance to the finished item.

Prototyping Solutions for Item Design and Improvement

Prototyping Services for Product Style and Improvement


Prototyping is an integral element of product design and style and development. There are numerous companies which strive tough to achieve good results in the field of engineering. But success does not come only with knowledge the way to implement those expertise in a sensible way is what defines achievement.


Item design and improvement is what every company delivers, but in order to succeed what matters is the high quality or the finishing that you add to that distinct product style or improvement.


1 of the profitable ways of succeeding in this extremely stream is building a prototype of the item. The protype is required to define the early sample of the solution so that any changes to be made can be decided ahead of the sensible implementation of the solution.


The output of the item aids the organization to function on their item so that there ought to not be any bug once the product is in the development mode.  The newest prototyping approach that is employed is Rapid Prototyping, which is the automatic execution of the whole building process. This kind of prototyping is performed employing numerous softwares such as Autodesk, 3D Method, AutoCAD and so on.


This kind of prototyping not only defines the final outcome of the item but also defines a simple protocol for developers which even make their operate easier and therefore adds efficiency to their function. Effective solution development is the only issue on which the organization focuses on, because its not only about establishing the solution but about establishing the item with an edge more than other folks since no matter how huge an organization you have, you will usually discover fine competing competitors. Hence, to sustain in the industry you require to give your products one thing above other people. Speaking about item improvement, it does not matter a lot that “What is your solution?” as an alternative what matters is “How is your product?”


There are numbers of item improvement organizations in the marketplace, but really handful of who can serve up to the expectation of the customers.

Injection Molding Procedure

Injection Molding Procedure


What is Injection Molding?


Injection molding is a manufacturing procedure that forms plastic (each thermoplastic and thermosetting) into usable shaped parts, such as a toothbrush.


How does injection molding perform?


Prior to any melting of plastic can take place, a mold have to 1st be manufactured. Molds are normally composed of steel or aluminum and comes in two components, the injection mold and the ejector mold. The design and style of the solution is precision machined among the two pieces of the mold.


Following the mold is complete, it is installed into an injection molding machine. Plastic resin is poured into the hopper for heating and mixing at higher temperatures. The molten plastic is then forced or “injected” into the mold cavity. As the mold remains cool, the injected plastic speedily solidifies and is formed into the shape of the cavity.


What is the injection molding method?


Step 1

Plastic resin is stored and feed into the injection molding machine via the hopper. Plastic resin can be in the type of beads, granules, or flakes.

Step two

For most injection molding machines, the hopper feeds into the injection barrel via gravity. There are also vacuum loading systems offered in the marketplace. The injection barrel melts the plastic and prepares it for injection into the mold cavity. Any coloring is typically added at this stage.

Step 3

The molten plastic is driven by means of the injection barrel via a single of two distinct approaches. Either a reciprocating screw drives the plastic forward, or a hydraulic ram is employed. The reciprocating screw is more precise and is for that reason more commonly employed.

Step 4

As soon as the molten plastic is injected into the empty mold cavity, it is permitted to cool and solidify. As the mold consists of two parts, they separate to enable the part to fall out.

Step 5

Some elements do not basically fall out, instead an extra ejector pin is added to knock the component out of the mold when it solidifies.


What varieties of products can injection molding create?


Injection molding is the most common strategy of plastic component manufacturing. It is swift, accurate, requires low labor price and scrap loss, and can be used with numerous polymer sorts. The concern with injection molding is its higher initial price for creating the mold, which can variety from hundreds to thousands of dollars (depending on size, sophistication, surface finishes, etc…).


Some examples of injection molded components include: tiny plastic components, bottle caps, pocket combs, model kits (model plane, model automobiles, and so forth), CD &amp DVD situations, automotive dashboards, Lego pieces, etc…

Quoting from Wikipedia: Jaguar E-Type:


• • • • •


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.[2] In 2004, Sports Car International magazine placed the E-Type at number one on their list of Top Sports Cars of the 1960s.

Overview


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.


Concept versions


E1A (1957)


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


E2A (1960)


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.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.[7] 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.[7]


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.[8] These are sometimes referred to as "Series 1¼" cars.[9] Production dates on these machines vary but in right hand drive form production has been verified as late as March 1968.[10] 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.[11]

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[12] 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.[15]


Graham[12] lists production at 15,290.


Series 3 production numbers from xkedata.com[13]: [omitted — Flickr doesn’t allow tables]


Limited edtions


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.


The cars were entered in various races but, unlike the C-Type and D-Type racing cars, they did not win at Le Mans or Sebring.


Motor Sport


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.

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.[2] In 2004, Sports Car International magazine placed the E-Type at number one on their list of Top Sports Cars of the 1960s.

Overview


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.


Concept versions


E1A (1957)


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


E2A (1960)


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.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.[7] 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.[7]


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.[8] These are sometimes referred to as "Series 1¼" cars.[9] Production dates on these machines vary but in right hand drive form production has been verified as late as March 1968.[10] 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.[11]

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[12] 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.[15]


Graham[12] lists production at 15,290.


Series 3 production numbers from xkedata.com[13]: [omitted — Flickr doesn’t allow tables]


Limited edtions


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.


The cars were entered in various races but, unlike the C-Type and D-Type racing cars, they did not win at Le Mans or Sebring.


Motor Sport


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.

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[12] 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.[15]


Graham[12] lists production at 15,290.

Limited edtions


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.


The cars were entered in various races but, unlike the C-Type and D-Type racing cars, they did not win at Le Mans or Sebring.


Motor Sport


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.
