London never disappoints the car spotter !

This DeLorean appeared out of nowhere in a small street close to Soho in the night.

The DeLorean DMC-12 (commonly referred to simply as the DeLorean as it was the only model ever produced by the company) is a sports car manufactured by John DeLorean's DeLorean Motor Company for the American market from 1981–83. The car features gull-wing doors and an innovative fiberglass chassis and underbody structure, along with a brushed stainless steel body. The car became widely known and iconic for its appearance and was modified as a time machine in the Back to the Future film trilogy.

HYSTORY

The first prototype appeared in October 1976. Production officially began in 1981 in Dunmurry, a suburb of southwest Belfast, Northern Ireland, where the first DMC-12 rolled off the production line on January 21. Over the course of production, several features of the car were changed, such as the hood style, wheels and interior. About 9,000 DMC-12s were made before production halted in early 1983.

The DMC-12 was the only model produced by the company, which was later liquidated as the US car market went through its largest slump since the 1930s. In 2007, about 6,500 DeLorean Motor cars were believed still to exist.

BODY

The body design of the DMC-12 was a product of Giorgetto Giugiaro of Ital Design and is panelled in brushed SS304 stainless steel. Except for three cars plated in 24-carat gold, all DMC-12s left the factory uncovered by paint or clearcoat. Painted DeLoreans do exist, although these were all painted after the cars were purchased from the factory. Several hundred DMCs were produced without stainless panels, for training workers, and are referred to as "black cars" or "mules", in reference to their black fiberglass panels instead of stainless, though these were never marketed. Small scratches in the stainless steel body panels can be removed with a non-metallic scouring pad (since metal pads can leave iron particles embedded in the stainless steel which can give the appearance of the stainless "rusting"), or even sandpaper. The stainless steel panels are fixed to a fiberglass, monocoque underbody. The underbody is affixed to a double-Y frame chassis, derived from the Lotus Esprit platform.

The unpainted stainless body creates challenges during restoration of the cars. In traditional automotive body repair, the panel is repaired to be as original ("straight") as possible and imperfections are sculpted back to form with body filler like Bondo or lead (body solder). This poses no problem (aside from originality) with most cars, as the filler will be hidden by the car's paint (for example, most new cars have filler hiding the seam where the roof meets the quarter panel). With an unpainted stainless body, the stainless steel must be reworked to exactly the original shape, contour, and grain—which is a tremendously difficult job on regular steel (a dented or bent panel is stretched and a shrinking hammer or other techniques must be used to unstretch the metal) and even more difficult with stainless due to its tendency to work-harden. Furthermore, it is exceedingly difficult to paint stainless steel due to difficulties with paint adhesion. DeLorean envisioned that damaged panels would simply be replaced rather than repaired; each DeLorean service center today has at least one experienced body repair person on staff, and there are decades worth of new stainless panels still available in most instances.

Another unusual 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 a hydraulic pump in the Bricklin SV-1, although these designs had structural or convenience disadvantages. The DMC-12 features heavy doors supported by cryogenically preset torsion bars and gas-charged struts. These torsion bars were developed by Grumman Aerospace (and built by Unbrako in the UK, a division of SPS Technologies of Jenkintown, PA) to withstand the stresses of supporting the doors. A popular misconception of the DMC-12's gull-wing doors is that they require far more side clearance to open relative to ordinary side-hinge doors, such as when parked in a parking lot. In fact, the opposite is true: the DMC-12 requires far less clearance than side-hinge doors, and this can be physically demonstrated. This misconception of side clearance may stem from a misunderstood location of the hinge point of the doors by persons unfamiliar with DMC-12s. These doors, when opening, only require 11 inches (28 cm) clearance outside the line of the car, making opening and closing the doors in crowded spaces 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. Additionally, the doors featured red and amber "safety" lights around the perimeter. These lights illuminated when the door was open and could be seen from the front, rear or side of the vehicle at night or low light situations.

ENGINE AND DRIVE TRAIN

The engine is a Peugeot-Renault-Volvo (PRV) 2.85 litre V6 which was designed and built under special contract with the DMC Company. These PRV engines were a development of the 2.7 litre V6 in the Renault 30, and were built in the PRV Factory in Douvrin, Northern France. The gearbox, also designed by PRV, was built at the Renault facility near Caen in Normandy. The engines and gearboxes were shipped weekly by sea from the PRV Factories to the DMC Factory in Dunmurry, Northern Ireland.

PERFORMANCE

DeLorean's comparison literature noted that the DMC-12 could achieve 0–60 miles per hour (0–97 km/h) in 8.8 seconds, when equipped with a manual transmission. When equipped with an automatic transmission, the DeLorean would accelerate from 0–60 miles per hour (0–97 km/h) in 10.5 seconds as tested by Road & Track magazine.
