By the mid-’60s the European car makers started realising that (more) money could be made with expanding their line-ups; something that US brands had been doing for years. Opel (essentially being American) saw an opportunity between the midsized Rekord C and the big Admiral.
Developing a model was easy: the Rekord line-up was cut down and six-cylinder Rekords were renamed Commodore. Apparently nobody noticed this little trick, and the Commodore became a success. .
When it was time to start working on a new Rekord, a new Commodore was developed alongside. The very handsome Rekord D-Commodore B twins were launched in January 1972. Yet again the Commodores were the six-cylinder versions of the Rekord, that could be recognised by their more impressive front grille and more chrome. The Commodore B was sold as a four-door sedan and a two-door coupé.
Opel built 140,827 Commodore B’s, 42,279 of them being coupé models. That seems quite a lot, but coupés were the type of car everybody wanted back in the ‘70s.
The Commodore B was succeeded by the Commodore C in 1977 -again Rekord based- but by then the niche between the Rekord and the Senator had become too small. The Commodore was discontinued in 1982. .
