The Bitter CD was a vehicle manufactured by Erich Bitter Automobil GmbH between the years of 1973 an 1979. This specific version was considered to be one of the most popular (if not short-lived) models. One of the aspects which made the Bitter CD rather different from other innovative vehicles is that it was essentially a re-bodied version of previously produced cars. This was the very same concept that founder and former racer Erich Bitter employed in general. The Bitter CD was designed as a three-door hatchback and this unit was first displayed as a prototype at the Frankfurt Auto Show in 1969. “CD” was an acronym for “Opel Coupe Diplomat”. Designers included Charles M. Gordon (the future vice president of General Motors), George A. Gallion, Herbert Kilmer and Erhard Fast. The prototype proved to be so popular that Opel began contemplating production models.
