DeLorean. When Citroën learned of DMC plans to turbocharge the engine, Citroën suggested that DMC find another engine. Eventually the fuel-injected V6 PRV engine (Peugeot-Renault-Volvo) was selected. As a result, the engine location had to be moved from the mid-engined location in Prototype 1 to a rear-engined location in Prototype 2, a configuration which would be retained in the production vehicle. The chassis was initially planned to use elastic reservoir moulding (ERM), which would lighten the car and lower its production costs. DeLorean had purchased patent rights to the essentially untested ERM technology, and it was eventually found unsuitable. Prototype 1's interior was significantly different from the production vehicle's. Prototype 1 had a prominent full-width knee bar, as it was intended to be a safety car. A medium brown leather covered the seats, but they were much flatter and did not have the comfort and support of the production seats. A black steering wheel with a fat center was intended to hold an airbag and the driver had a full set of Stewart-Warner gauges. A central warning system would check various fluid levels and even warn of low brake pad thickness though, even at this time, it was suspected that production cars would not have this feature. These and other changes to the original concept led to considerable schedule pressures. The design was deemed to require almost complete re-engineering, which was turned over to English engineer Colin Chapman, founder of Lotus Cars. Chapman replaced most of the unproven material and manufacturing techniques with those then employed by Lotus, including a steel backbone chassis. In order to train the workforce, a small number of pre-production DeLoreans were produced with fiberglass bodies and are referred to as "black cars" or mules. After several delays and cost overruns, production at the Dunmurry factory, located a few miles from Belfast City Centre, finally began in late 1980. Around this time DMC officially dropped the name DMC-12 on its now $25,000 car in favor of the model name DeLorean. The DeLorean sports car, as it was described in advertisements, began production in December 1980 with the first production car rolling off the assembly line on January 21, 1981. The DeLorean Motor Company was placed into receivership in February 1982 and filed bankruptcy on October 26 of that year, just a few days after the arrest of its founder, John DeLorean, on drug trafficking charges.
