The De Lorean DMC-12 is a sports car which was manufactured by the De Lorean Motor Company from 1981 until 1983. It is most commonly known as the De Lorean, as it was the only model ever produced by the company. The DMC-12 featured gull-wing doors with a brushed stainless steel body. It was famously featured in the Back to the Future trilogy.

The first prototype was completed in 1978, and the final chassis was shared with the Lotus Esprit. Production began officially in 1981 at the DMC factory in Dunmurry, Northern Ireland. During its production, several aspects of the car were changed, such as the hood (bonnet) style, wheels and interior. About 8,583 DMC-12s were made before production ended in 1983, and as of 2006, 6,000 are estimated to be in existence.

Despite being produced in Northern Ireland, DMC-12s were primarily intended for the American market. Therefore, all of the production models were left-hand drive (designed to be driven on the right side of the road). Some of them were converted to right-hand drive by specialist mechanics in the United Kingdom, but no right-hand drive De Lorean was ever put into production, thus limiting the vehicle's popularity in the United Kingdom.

History

A 1981 De Lorean DMC-12 with the gull-wing doors closed. A De Lorean DMC-12 with the gull-wing doors open.In October 1976, the first prototype De Lorean DMC-12 was completed by William T. Collins, chief engineer and designer (formerly chief engineer at Pontiac). Originally, the car's rear-mounted power plant was to be a Citroën Wankel rotary engine, but was replaced with a French-designed and produced PRV (Peugeot-Renault-Volvo) fuel injected V-6 because of the poor fuel economy of the rotary engine, an important issue at a time of world-wide fuel shortages. Collins and De Lorean envisioned a chassis produced from a new and untested manufacturing technology known as Elastic Reservoir Moulding (ERM), which would contribute to the light-weight characteristics of the car while presumably lowering its production costs. This new technology, for which De Lorean had purchased patent rights, would eventually be found to be unsuitable for mass production.

These and other changes to the original concept led to considerable schedule pressures. The entire car was deemed to require almost complete re-engineering, which was turned over to engineer Colin Chapman, founder and owner of Lotus. Chapman replaced most of the dubious material and manufacturing techniques with those currently being employed by Lotus; specifically, the existing suspension and chassis from the Lotus Esprit were used in the DMC-12. The original Giorgetto Giugiaro body design was left mostly intact, as were the distinctive stainless steel outer skin and gull-wing doors. (Giugiaro had also designed the Lotus Esprit.)

The DMC-12 would eventually be built in a factory in Dunmurry, Northern Ireland, a neighborhood only a few miles from Belfast City Centre. Construction on the factory began in October 1978, and although production of the DMC-12 was scheduled to start in 1979, engineering issues and budget overruns delayed production until 1981. By that time, the unemployment rate was high in Northern Ireland and local residents lined up to apply for jobs at the factory. The workforce was comprised of both Protestants and Catholics who were happy to put religious differences aside and work together as a team. The production personnel were largely inexperienced, but were paid premium wages and supplied with the best equipment available. Most quality issues were solved by 1982 and the cars were sold with a five-year, 50,000-mile (80 000 km) warranty.

Although the De Lorean Motor Company went bankrupt in late 1982 following John De Lorean's October 1982 arrest, unassembled DMC-12s were completed by Consolidated Industries (now part of Kapac Co.). A total of about 9,200 DMC-12s were produced between January 1981 and December 1982. Almost a fifth of these were produced in October 1981. Very few cars were produced between February and July 1982, although serious production returned in August that year. At least one source indicates that only 8,583 DMC-12s were ever produced.

Construction The DMC-12 features a number of unusual construction details, including gull-wing doors, unpainted stainless-steel body panels, and a rear-mounted engine.

Body The body of the DMC-12 was designed by Giorgetto Giugiaro and clad entirely in brushed SS304 stainless steel. Except for three cars plated in 24k gold, all DMC-12s left the factory uncovered by paint or clearcoat.[4] Painted De Loreans do exist, although these were all painted after the cars were purchased from the factory. Several hundred fiberglass-bodied "black car" DMC-12s were produced to train workers, although these were never marketed. Small scratches in the stainless steel body panels can reportedly be removed with a scouring pad.[5] The stainless steel panels are fixed to a glass-reinforced plastic (GRP, fiberglass) monocoque underbody. The underbody is affixed to a double-Y frame chassis, derived from the Lotus Esprit platform.

Another novel feature of the DMC-12 is its gull-wing doors. The common problem of supporting the weight of gull-wing doors was solved by other manufacturers with lightweight doors in the Mercedes-Benz 300SL and an air pump in the Bricklin SV-1, although these designs had structural or convenience issues. The DMC-12 features heavy doors supported by cryogenically preset torsion bars and gas-charged struts[6]. These torsion bars were manufactured by Grumman Aerospace to withstand the stresses of supporting the doors.[7] These doors only extend 11 inches (264 mm) outside the line of the car, making opening and closing the doors in crowded parking lots relatively easy. Much like the doors fitted to the Lamborghini Countach, the DMC-12 doors featured small cutout windows, because full-sized windows would not be fully retractable within the short door panels.

Engine

The Peugeot-Renault-Volvo V6 engine inside a De Lorean car.The DMC-12 is powered by the PRV V6, developed jointly by Peugeot, Renault, and Volvo. The engine is derived from the Volvo B28F, fitted with a Bosch K-Jetronic fuel injection system and modified to be mounted in reverse. The PRV is a 90-degree layout, displaces 2.849 L (91 mm bore, 73 mm stroke), and has a compression ratio of 8.8:1. The engine block and heads are cast of light alloy and the engine features single overhead camshafts driving two valves per cylinder. When new, this engine was rated for 97 kW (130 hp) at 5,500 rpm and 208 N·m (153 ft lbf) at 2750 rpm. Fuel efficiency was said to be 12 L/100 km (19 mpg US, 22.8 mpg Imperial) and unofficial tests largely support this figure.

Two transmissions were available for the DMC-12: a three-speed automatic and a five-speed manual transmission, both with a final drive ratio of 3.44:1. The manual transmission is a Renault 30 gearbox. Most cars were fitted with manual transmissions. The engine in the DMC-12 is mounted behind the rear axle, much like the VW Beetle and Porsche 911. The transaxle stretches forward between the axles.

Suspension The underbody and suspension of the DMC-12 were based largely on the Lotus Esprit, with a four-wheel independent suspension, coil springs, and telescopic shock absorbers. The front suspension used double wishbones, while the rear was a multi-link setup. In its original development stages, the car is said to have handled quite well. Considering that Lotus's reputation was built largely on the handling prowess of the cars the company produced, the DMC-12's smooth ride wasn't a surprise. Unfortunately, changing safety standards in the U.S. required modifications to the suspension system and an increase in the vehicle's factory ride height, both of which had adverse effects on the car's handling capabilities.

Steering was rack and pinion, with an overall steering ratio of 14.9:1, giving 2.65 turns lock-to-lock and a 35 ft (10.67 m) turning circle. DMC-12s were originally fitted with cast alloy wheels, measuring 14 in (356 mm) in diameter by 6 in (152 mm) wide on the front and 15 in (381 mm) in diameter by 8 in (203 mm) wide on the rear. These were fitted with Goodyear NCT steel-belted radial tires; because the engine is mounted in the very rear of the vehicle, the DMC-12 has a 35%/65% front/rear weight distribution.[14]

The DMC-12 features power-assisted disc brakes on all wheels, with 10 in (254 mm) rotors front and 10.5 in (267 mm) rear.

Performance

The grey interior and manual transmission in a DMC-12.John De Lorean had originally envisioned that the car would produce somewhere around 200 horsepower, but eventually settled on a 170 horsepower output for the engine. However, stringent new US emissions regulations required that parts such as catalytic converters be added to the vehicle before it could be sold in that country. Although the new parts qualified the vehicle for sale in the US, they caused serious reductions to power output, to 130 horsepower. The 40 horsepower loss seriously impeded the DMC-12's performance, and when combined with the forced changes to the vehicle's suspension system, the US versions were regarded as disappointing. De Lorean's comparison literature noted that the DMC-12 could achieve 0–60 mph (0–96 km/h) in 8.8 s, which would have been good for the time, but Road & Track magazine clocked the car at 10.5 s. However, it's possible that the factory performance numbers were achieved using a European spec car with the 170 horsepower engine.[15]

Pricing New DMC-12s had a suggested retail price of $25,000 ($650 more when equipped with an automatic transmission); this is equivalent to approximately $56,000 in 2005 dollars. There were extensive waiting lists of people willing to pay up to $10,000 above the list price; however, after the collapse of the De Lorean Motor Company, unsold cars could be purchased for under the retail price.

The DMC-12 was only available with seven options including automatic transmission ($650), a car cover ($117), floor mats ($84), black textured accent stripes ($87), grey scotch-cal accent stripes ($55), a luggage rack ($269) and a ski-rack adapter. The standard feature list included stainless steel body panels, gull-wing doors with cryogenically treated torsion bars, leather seats/trim, air conditioning, a high-output stereo system, power windows, locks, mirrors, steering wheel adjustable for both rake and reach, tinted glass, body side moldings, intermittent windshield wipers, and an electric rear window defogger.

Prices for DMC-12s vary widely with quality and demand, which varies over time. As of early 2006, a Delorean in good to great condition can be found for around $17,000 to $20,000. Mint condition cars can fetch up to $30,000. There are an estimated 6,000 surviving DMC-12s today. A Texas-based company called the DeLorean Motor Company sells refurbished DMC-12s starting at $42,500, priced according to condition. The cars are available with modern amenities, such as performance engine upgrades, two-toned heated/cooled seats, satellite radio options, enhanced Eibach suspension, audio sound system upgrades, and high-intensity discharge (HID) headlights. This company has no affiliation with the original DeLorean Motor Company.

Production changes Although there were no typical "yearly" updates to the De Lorean, several changes were made to the De Lorean during production. John De Lorean believed that model years were primarily a gimmick used by automobile companies to sell more cars. Instead of making massive changes at the end of the model year, he implemented changes mid-production. This resulted in no clear distinction between the 1981, 1982 and 1983 model years, with subtle changes taking place almost continuously throughout the life of the De Lorean. The most visible of these changes related to the hood style.

Hood styles

Early 1981 Hood 1983 hoodThe original hood of the De Lorean had grooves running down both sides. It included a gas flap to simplify fuel filling. The gas flap was built so that the trunk could be added to the total cargo area of the De Lorean. These cars typically had a locking gas cap to prevent siphoning. In 1981, the hood flap was removed from the hood of the cars (although the hood creases stayed). This style was retained well into 1982. Based on production numbers for all three years, this hood style is probably the most common. After the supply of locking gas caps was exhausted, the company switched to a non-locking version (resulting in at least 500 cars with no gas flap, but with locking gas caps). The final styling for the hood included the addition of a De Lorean logo and the removal of the grooves, resulting in a completely flat hood. All changes to the hood were made not to alter the look of the car, but for a much more practical reason: Production was faster with the non-grooved design.

Other changes

Early pull strap Later style one-piece bolster Mid 1981 silver wheelJohn DeLorean was well over six feet (183 cm) tall, and he designed the car to comfortably fit someone of his stature. For shorter people, the addition of a pull strap made closing the doors much easier from the inside. Pull straps were manufactured as an add-on for earlier vehicles in November 1981. These attach to the existing door handle. Late-model 1981 cars, and all cars from 1982 and 1983, have doors with permanent pull straps attached.

The side bolstering in the De Lorean was originally separate from the main interior pieces. There is a tendency to place pressure on this piece when entering and exiting the car. This will eventually cause the bolstering to become separated from the trim panel. To help fix this problem; cars built in and after late 1981 have one solid trim piece with the bolster permanently attached.

As an addition to later cars, a foot rest — in the form of an unusable pedal — was added to the cars to help prevent fatigue while driving. This is one of the few changes that is directly tied to a model year. These were not built in to any 1981 vehicles, and were added to all cars starting with 1982 production.

Although the styling of the De Lorean's wheels remained unchanged, the wheels of early-model 1981 vehicles were painted grey. These wheels sported matching grey centre caps with an embossed DMC logo. Early into the 1981 production run, these were changed to a polished silver look, with a contrasting black centre cap. The embossed logo on the centre caps was painted white to add contrast.

In 1981, the De Lorean came stocked with a Craig radio; this was a standard 1980s tape radio with dual knob controls. Since the Craig did not have a built-in clock, one was installed in front of the gear shift. De Lorean switched to an ASI stereo in the middle of the 1982 production run. Since the ASI radio featured an on-board clock, the standard De Lorean clock was removed at the same time.

The first 2,200 cars produced used a windshield embedded antenna. This type of antenna proved to be inadequate for most motoring needs, so a standard whip antenna was added to the outside of the front right quarter panel. While improving radio reception, this resulted in a hole in the stainless steel, and an unsightly antenna. As a result, the antenna was again moved, this time to the rear of the car. Automatic antennas were installed under the grills behind the rear driver's-side window. While giving the reception quality of a whip antenna, these completely disappear from view when not in use.

The small sun visors on the De Lorean have vinyl on one side, and headline fabric on the other side. Originally these were installed such that the vinyl side would be on the bottom when not in use. Later on in 1981, they were reversed so that the fabric side would be on the bottom.

The original alternator supplied with the early production DMC-12s could not provide enough current to supply the car when all lights and electrical options were on; as a result, the battery would gradually discharge, leaving the driver stranded on the road. This happened to De Lorean owner Johnny Carson shortly after he was presented with the vehicle.

Special DMC-12s Several special-edition DMC-12 cars have been produced over the years, including several that were used in the films of the Back to the Future trilogy. Twelve De Loreans were used and modified with props after purchase to make them look like time travel machines. At least three DMC-12s were used in pornographic films that parodied the Back to the Future trilogy.

One of several De Lorean prototypes is still in existence, and is currently undergoing a complete restoration at De Lorean Motor Company of Florida. Production of the De Lorean started at VIN 500. VINs #502 and 530 were used by Legend Industries as a proof of concept for a twin-turbo version of the standard De Lorean PRV-V6 engine. VINs 502 and 530 are undergoing restoration at PJ Grady's in New York. Only one other twin-turbo engine is known to exist: it was purchased in the late 1990s by Marc Levy of New Jersey, an enthusiast, who swapped it with his standard De Lorean.

VIN 500, notable for being the first production De Lorean to roll off the line in 1981, is on display in the Crawford Auto-Aviation Museum in Cleveland, Ohio.

Only 23 right-hand drive models were made for use in the United Kingdom, and as of 2002 these are valued at £25,000 each.

A gold plated DeLorean in Reno, NevadaA De Lorean/American Express promotion planned to sell one hundred 24k gold-plated DMC-12s for $85,000 each to its gold card members, but only two were sold. One of these was purchased by Roger Mize, president of Snyder National Bank in Snyder, Texas. VIN #4301 sat in the bank lobby for over 20 years before being loaned to the Petersen Automotive Museum of Los Angeles. It has a saddle brown interior rather than the stock black/grey interior, and an automatic transmission.

The second gold-plated American Express DMC-12 is located at the William F. Harrah Foundation/National Automobile Museum in Reno, Nevada. This car, VIN #4300, is the only one of the three existing gold-plated examples to be equipped with a manual transmission. Like its golden siblings, it is a low-mileage vehicle with only 1,442 miles (2,307 km) on the odometer.

A third gold-plated car exists with 636 miles (1,018 km) clocked up; it carries the VIN plate for the last production De Lorean, #20105.[24] This car was assembled with spare parts that were acquired by American Express. All necessary gold-plated parts were on hand, with the exception of one door. The car was assembled after another door was gold-plated, though the added door does not precisely match the rest of the car in color and grain. The car was first acquired by the winner of a department store raffle. Consolidated International, which owned the department store, had purchased 1,374 DMC-12s during the De Lorean Company's financial troubles, acquiring the remaining stock after the company went into receivership. Now held by a private owner in La Vale, Maryland, the third and last gold-plated De Lorean is currently for sale at the price of $250,000. Both this car and the example in Reno have saddle-brown leather interiors, a color scheme which was intended to become an option on later production cars. However, these two cars were the only ones to be thus equipped from the factory.

Insurance costs on the gold vehicles were approximately $1,000 a month (in 1981 dollars) and a small dent in the car body could cost as much as $24,000 to repair.

De Lorean today

De Loreans lined up for the 2004 Delorean Car Show. De Lorean culture lives on through the existing owners and their passion for the car. Children of the 80s are now able to afford the car that captured their imagination in "Back To The Future". A surge in De Lorean interest is evidenced by the cars' eBay availability, and pop-culture references abound. As of early 2006, a Delorean in good to great condition can be found for around $17,000 to $20,000. Mint condition cars can fetch up to $30,000.

Gatherings and communications Most notably in the United States, owners have gathered bi-annually for the De Lorean Car Show which draws people from all over the world to a different location each time. "Back to the Future" stars and writers have made appearances, and even John De Lorean was known to attend before he died. Besides this main event, local clubs hold events throughout the year featuring driving tours, road rally scavenger hunts, tech sessions and more. Online, the De Lorean owner base keeps in contact using a mailing list called the De Lorean Mailing List or the DML.

A De lorean at a car show in 2005.The group is home to thousands of De Lorean owners and enthusiasts across the world and features active conversations all the time. The DML is moderated on a rotating basis. After some members became upset with what was seen as too much moderation by not allowing off-topic posts a separate mailing list was created to be an alternative place for De Lorean fans to speak without moderation. The DMC Forum has less moderation and is generally an outlet for people to speak freely about anything delorean or sometimes non-De Lorean related. Both groups are highly active and are part of the Yahoo Groups service.

Repair shops Keeping the cars on the road are the specialties of the four remaining De Lorean repair shops: DeLorean Motor Company, PJ Grady DeLorean, DeLorean Motor Center, and DeLorean 1. These specialty shops service the De Loreans still on the road. The Delorean Motor Company bought the largest remaining stock of original parts from the Kapac corporation. The new DMC (commonly known as "Delorean Houston", "Houston" or "DMC Texas") is the only place to find some rare parts, though they also sell through the other full service DeLorean shops. Their resources have also allowed some unavailable parts to be produced again, so that replacements for minor parts (such as switches) can now be had for a reasonable price. Overall, obtaining parts is neither difficult nor expensive.

Magazines Along with the resurging interest in the car, new magazine publications have begun to be produced. The De Lorean Car Show has its own magazine that is currently seen as the main publication in the community. Delorean Car Show Magazine (Known just as DCS) is published quarterly by Ken Koncelik. Along with DCS there is Gullwing Magazine and Deloreans, which is published by the new DMC in Texas. While these publications at times can be costly to purchase, the content is provided by the owner base, which generates more interest.

Previously the only magazine on the market was Delorean World, which was published by the Delorean Owners Association (DOA). This magazine was seen by all owners as an essential part of ownership. The quality of the magazine was always high while the content was useful. The Winter 2002 issue of Delorean World would be the last issue in the classic form. At this point the DOA was changing hands with their officers. With this change the magazine was reborn as DW Magazine. The publication had a completely different feel and look to it. Inital response to the magazine was mixed with many people saying it looked like a travel magazine. The biggest fault of the publication's early editions were pictures that were obviousally photoshopped or doctored to put a delorean in the picture. In general, DW Magazine has fallen out of favor with most De Lorean owners.

DMC-12 on film The DMC-12 is today primarily known outside automotive circles for serving as the time machine designed by Dr. Emmett Brown in the Back to the Future trilogy. Brown gives a flattering rationale for choosing the DeLorean: "The way I see it, if you're gonna build a time machine into a car, why not do it with some style?" He also indicates that the stainless steel construction of the automobile is advantageous for a time machine (possibly due to the side effect of freezing during time travel, as indicated by the car being covered in frost after reaching its destination). In addition to elaborate enhancements for time travel, the fictional car was later modified with a fusion reactor and flying capabilities.

Six DMC-12s were co-opted for use in the making of the films. For the second and third films, producers replaced the underpowered stock engines in their production cars with Porsche engines.

In large part due to the popularity of Back to the Future, the DeLorean has been seen in many other contexts as well.

Actor Troy McClure drives a DMC-12 in The Simpsons season 7 episode "A Fish Called Selma". Glenn Gulia drives a DMC-12 in 1998's The Wedding Singer. A crew on The Discovery Channel show Monster Garage attempted to convert a DMC-12 into a hovercraft, but failed. The car was subsequently crushed under an APC. Cledus T. Judd drove a red DMC-12 in his music video "How Do You Milk a Cow?" spoofing Toby Keith's song "How Do You Like Me Now?" Peter Griffin drives a DMC-12 (appearing as the famous time machine) into a wall in the Family Guy episode "The Perfect Castaway". Another DMC-12 is seen in the Family Guy episode "One If by Clam, Two If by Sea". A DMC-12 can be also seen in the 2002 Polish film Haker. A DeLorean DMC 12 (Appearing as the BTTF time machine incarnation) can be seen briefly in the Fairly Odd Parents special "The Secret Origin of Denzel Crocker" as Timmy travels back in time to the 1980s. A DMC-12 can be seen in an episode of Get a Life. It is one among many possible time machines considered for use by Chris (as an obvious homage to Back to the Future), who ultimately rejects the DMC since a blinker light is out. In Rocky III, Rocky Balboa is seen posing with a DeLorean for a magazine during a scene which illustrates Balboa's success as a boxer and an American hero. Wooldoor Sockbat takes a "WoolDeLorean" in the Drawn Together episode "Captain Girl" in order to get to the city to stop the Mad Libber from blowing up the town's dam. The DMC-12 is the car used in The Last Starfighter to fly into space. In the Matlock episode "The Lemon", Les "Ace" Calhoun is talked into buying a DMC-12. In the Stargate Atlantis episode "Before I Sleep", Major Sheppard jokes that you would need a "really cool DeLorean" to travel back in time, (an obvious reference to Back to the Future). Another scene from this episode has a charactar explaining how a space ship has a time travel device. Sheppard blurts out "flux capacitor". In an episode of Eerie, Indiana one of the programme's stars is see to drive a DMC-12.

In the movie Donnie Darko, Dr. Monnitoff is explaining time travel. The dialogue goes: "So you have the vessel and the portal. And the vessel can be anything. Most likely a spacecraft." Donnie then says "Like a DeLorean". Sean Bean is seen in one in Moby's "We Are All Made of Stars" music video. In an episode of the animated TV show Harvey Birdman, the Jetsons return to the future in a Delorean, in a direct parody of Back to the Future.
