The Bitter SC was the second model of the German manufacturer Bitter . It replaced the Bitter CD and was also based on mass production technology from Opel. The official presentation of the Bitter SC Coupé took place in the spring of 1980 on the occasion of the Grand Prix of the Formula 1 of Monaco , where it was used as a safety car .

The SC was produced from the beginning of 1981 and was available over the years in three body versions. In addition to the coupe, the volume model of the series, from the spring of 1983, a convertible and from late summer 1985, a four-door sedan sedan called SC Sedan offered.

Until the discontinuation of production in the late autumn of 1989, a total of 488 copies of the Bitter SC series were produced. The indirect successor should be the prototype Type 3.

History 

The concept 

In the SC Erich Bitter repeated the conceptual approach of the CD. Again, he created an elegantly designed vehicle with Italian-style body and unproblematic mass production technology. Erich Bitter explained his preference for mass production technology with the following words: "I want my car to start without problems even after five days in the mountains after I have parked it in the mountains and gone skiing. What is the point of having a car that does not drive in difficult conditions? " 

In the case of the SC withdrew a resort to the sovereign motorized Diplomat technology: Opel had ceased production of the great diplomat in the summer of 1977. Although Bitter still had a number of diplomatic parts, due to which the continuation of the production of the CD was secured for another year; after that, however, the idea of ​​a new Bitter model was inevitable. Back in the spring of 1977, Bitter was able to secure the right to use Opel Senator A , which had not even been presented at the time, as the technical basis for a new coupé. The advantage of this technique was its reliability and easy availability.

In terms of sportiness and exclusivity, she remained well behind the diplomat's eight-cylinder. Some observers considered the technique downright bourgeois and saw it as a major reason for the low prevalence of SC  .

Unlike the CD, Bitter received no significant support from Opel except for the provision of the technical components. Bitter therefore had to carry out the development work on his own; It lasted two years and cost about 8 million German marks . Bitter was only able to do this by investing externally, namely by a Swiss industrialist.

Body 

Erich Bitter initially thought, as in the case of the CD only a coupe variant. The first draft of the body came from Erich Bitter himself. Unlike the CD of the new SC had no hatchback, but a saloon with a distinctive trapezoid line clear in the by Pininfarina -designed Ferrari 400 remembered and a similar elegance in appearance and in detail had. Like this, the Bitter SC had folding headlights. Bitter's design was then revised by Opel designers Henry Haga and Georges Gallion. The details of the design and the bodywork were finally by Giovanni Michelotti executed in Turin. All in all, the new car used many Opel parts, which were certainly not readily apparent on the exterior. Attachments such as lights and door handles came from mass producers, the rear lights, for example, were taken over by the Lancia Beta Montecarlo (and not, as often suspected, the Fiat X1 / 9 ), the front light units of the Ferrari Mondial .

RUST PROTECTION: Body surface cataphoresed as well as manually primer coated and painted—underbody protected by p, V.C. coating, including wheel arches and at sides of floor panels.
LIGHTING: Four halogen headlamps with low/ high beam. Integrated direction indicators combined with warning lamps—variable intensity instrument lighting—door courtesy switch controlled interior lighting with additional switch on instrument panel; two additional lamps in the rear passenger compartment.

Technology 

In the early development phase, there were plans to equip the SC with an eight-cylinder engine as before. As drive sources engines of Lamborghini - here the 3.5-liter eight-cylinder engine from the Urraco - and Holden were considered and certainly tested on test benches. However, this idea failed because of the noise and emissions performance of large engines  . Instead, Bitter made extensive use of the drive technology of the Opel Senator and the Opel Monza . The car was initially with a not significantly changed six-cylinder in- line engine equipped with a capacity of 2968 cc from the Senator. In the last model years, he was also equipped with a 3848 cc in-line six-cylinder Tuner Mantzel. Individual vehicles eventually received a four-wheel drive from Ferguson.

The production

As with the Bitter CD, the production of the SC was largely outsourced. According to the common concept for small series manufacturers, the body was to be manufactured in an external factory before being transported to Bitter in Schwelm and assembled there with drive technology. At the CD the body had been made by Baur .

However, this path was eliminated for the SC. After the last CD had left the band at Baur at the end of 1979, Baur had found an alternative with the production of the BMW M1 , which was so exhausted that there was no capacity left to build the new Bitter. Erich Bitter therefore deviated to northern Italy, where for decades there were a large number of small, independent bodyworks, which made for other vehicle manufacturers either by hand or in small series superstructures. First, the choice fell on the Carrozzeria OCRA in Turin , a relatively young company with little experience. Between early 1981 and early 1982, OCRA introducedA total of 79 bodies ago, the overall were of poor quality. Given the use of Soviet recycled sheet metal, the cars were extremely rust-prone; Some vehicles began rusting just a few months after delivery.

In the spring of 1982, Bitter terminated the contract with OCRA . The production was then relocated to the also based in Turin Carrozzeria Maggiora , a company as experienced as well as renowned, which at that time also produced bodies for Maserati and Bristol . Individual vehicles are said to have been completed at Zagato  . The leather for the interior was sourced from SALT in Turin . By the end of 1983, the vehicles were completed at Bitter in Schwelm. However, the small plant soon came to its limits, because there usually only one car per week could be completed.

In view of the planning for an expansion of production, Bitter finally found the opportunity to complete the cars at Steyr Daimler Puch in Graz . There, about three to four cars were produced weekly by the end of 1989 .

Body versions 

Coupe 

The SC Coupe came in spring 1981 as the first version on the market and thus represented the volume model of the series dar. With 461 manufactured copies, it was also the most common variant.

Cabriolet

In the spring of 1983, the series was supplemented by the SC Cabriolet. The hood was based on a design that had developed the supplier Keinath for a limited series of 144 convertibles based on the Opel Monza.

By the end of 1989, only 22 convertibles.

Sedan 

The Sedan supplemented from late summer 1985, the model range. This was a four-door limousine sedan, which was designed primarily for sale in the US . The vehicle was based on an extended chassis.

The first prototype was created in 1984. The SC Sedan was an extended version of the coupe dar. Drive technology and roof height remained unchanged. The prototype was powered by the 3.0-liter six-cylinder Opel Senator and had a manual five-speed gearbox. The production cars, which were manufactured from mid-1985, deviated in some details from this prototype. All production vehicles had a higher roof. They were powered by the 3.9-liter mantzel engine and all had an automatic transmission.From SC Sedan until the middle of 1988, only four production vehicles were produced. Three of them still exist; they are in the USA. The prototype today belongs to a Dutch collector .
