The
Bitter CD was originally an Opel concept displayed in 1969 and
1970. When Opel decided not to put the CD into production Erich
Bitter stepped in and purchased the project.
Production of the Bitter CD began in 1971 and was based on a
shortened Opel Diplomat chassis, the suspension was revised
to handle the lighter CD but otherwise the running gear remained
much the same.
Power for the Bitter CD came from a 5.4 litre V8 developing
230 horsepower.
