The Commodore B was based on the Rekord D, and launched in 1972. As in the previous generation, four models were offered: 2500 S, 2500 GS, 2800 GS, and 2800 GS/E, as a four-door [[Sedan (automobile)|saloon]] and two-door [[hardtop]] [[coupé]] (although the [[fastback]] design was replaced by a more conventional [[Three-box styling|three-box design]]). Power of the 2.5-litre engine was {{cvt|115|or|130|PS|kW|0}} depending on the specifications (25S/25H), while carburetted 2.8-liters had {{cvt|130|or|142|PS|kW|0}}. The fuel injected 2.8 used in the GS/E has {{cvt|160|PS|kW|0}}.

The Rekord and Commodore were also assembled as [[Complete knock down|CKD]] kits in [[Belgium]] and [[Switzerland]] in the 1970s. These cars carried the name '''[[Ranger (car)|Ranger]]''' and differed from the originals in having different grilles and trim. These cars were exported to various countries.

In 1974, due to new regulations regarding pollutant emissions, the 2.5-litre models were dropped and the 2.8&nbsp;L models were detuned to {{cvt|129|/|140|/|155|PS|kW|0}}. Commodore B production ended in 1977.

The Commodore B series was like the A series briefly used in motorsports, and the extreme "Jumbo" Commodore raced in the 1974 "interserie". It used a [[Chevrolet big-block engine#366|6.0-litre V8 engine]] and had large wings which almost made it unrecognizable as an Opel. It never enjoyed much success despite its massive powerplant and impressive output.

===Foreign assembly===
Opel Commodores were also built in [[Iran]] between 1974 and 1976 under the name '''Chevrolet Iran''' 2800, 2500, Royal and Custom with both 2.5&nbsp;L and 2.8&nbsp;L engines by [[Pars Khodro]] (General Motors Iran).<ref>{{citation | url = https://books.google.com/books?id=KCmuCwAAQBAJ&q=chevrolet+royal+iran&pg=PA6 | title = The Economies of the Middle East | first = Rodney | last = Wilson | publisher = MacMillan Press Ltd. | location = London | date = 1979 | page = 6 | isbn = 9781349034215 }}</ref><ref name=SS03>{{cite journal | ref = SS03 | title = Katalog Samochody Świata 2003 | journal = Samochody Świata | trans-title = World Car Catalogue 2003 | editor-first = Eligiusz | editor-last = Mazur | publisher = Print Shops Prego - Polska Sp. z o.o. | location = Warsaw, Poland | page = 226 | date = 2002 | issn = 1234-8198 }}</ref> The first Royale, also the first Chevrolet car built in Iran, left the production line on 15 January 1974. The Royale sold well initially, but the car had not been re-engineered for Iranian conditions and the low ground clearance coupled with carburettor troubles led to its reputation quickly being tarnished. The car was withdrawn by early 1977, replaced by the locally-built versions of the [[Buick Skylark]], [[Chevrolet Chevy II / Nova|Chevrolet Nova]], and [[Cadillac Seville]] (American origins).<ref name=jamejam>{{cite web | archive-url = https://web.archive.org/web/20180502075010/http://jamejamonline.ir/online/2569013432729587656 | archive-date = 2018-05-02 | url = http://jamejamonline.ir/online/2569013432729587656 | date = 2016-10-05 | first = S.M. | last = Qasemi | title = شورولت رویال؛ خودرویی که از آغاز به پایان رسید! | trans-title = The Chevrolet Royale: A car that was finished from the beginning! | language = fa | work = jamejamonline }}</ref>

It was also assembled in South Africa, where it was called the [[Opel Rekord Series D#ZA|Chevrolet 2500, 3800, and 4100]], and was a top seller in that market. These received inline-four or -six engines of Chevrolet origins, built locally.
