[[American Motors Corporation]] (AMC) was so convinced "...&nbsp;that the rotary engine will play an important role as a powerplant for cars and trucks of the future&nbsp;...", that the chairman, [[Roy D. Chapin Jr.]], signed an agreement in February 1973 after a year's negotiations, to build rotary engines for both passenger cars and military vehicles, and the right to sell any rotary engines it produced to other companies.<ref name="D1JXj">{{cite magazine |url= http://wardsautoworld.com/ar/auto_rearview_mirror_15/ |title=Rearview mirror |magazine=Ward's Auto World |date=2000-02-01 |access-date=2013-04-10 |archive-url= https://web.archive.org/web/20111105205047/http://wardsautoworld.com/ar/auto_rearview_mirror_15/ |archive-date=2011-11-05 |url-status=dead}}</ref><ref name="4aVPu">{{cite book |last1=Faith |first1=Nicholas |title=Wankel: The Curious Story Behind the Revolutionary Rotary Engine |publisher=Stein and Day |year=1975 |page= [https://archive.org/details/wankelcurioussto00fait/page/219 219] |isbn=978-0-8128-1719-5 |url-access=registration |url=https://archive.org/details/wankelcurioussto00fait/page/219}}</ref> AMC's president, William Luneburg, did not expect dramatic development through to 1980, but [[Gerald C. Meyers]], AMC's vice president of the engineering product group, suggested that AMC should buy the engines from Curtiss-Wright before developing its own rotary engines, and predicted a total transition to rotary power by 1984.<ref name="EylYW">{{cite book|url= https://books.google.com/books?id=IB2lMFqTTl8C&q=American+Motors+president+1980+Wankel+engine&pg=PA115 |title=The Wankel Rotary Engine: A History |first1=John B. |last1=Hege |date=24 August 2017 |publisher=McFarland |via=Google Books |access-date=2018-05-04|isbn=9780786486588}}</ref>

Plans called for the engine to be used in the [[AMC Pacer]], but development was pushed back.<ref name="N9680">{{cite magazine |first1=Robert |last1=Lund |title=Detroit Listening Post |page=26 |magazine=Popular Mechanics |date=May 1973 |volume=139 |issue=5 |url= https://books.google.com/books?id=htQDAAAAMBAJ&q=AMC+Gremlin+Wankel+engine&pg=PA26 |access-date=2012-08-14}}</ref><ref name="AyqBG">{{cite magazine|url= https://books.google.com/books?id=bOU8TD_BxwMC&q=AMC+Gremlin+Wankel+engine&pg=PA32 |first1=Jim |last1=Dunne |title=Detroit Report |magazine=Popular Science |page=32 |date=April 1973 |volume=201 |issue=4 |access-date=2011-12-11}}</ref> American Motors designed the unique Pacer around the engine.

The [[1973 oil crisis]] played a part in frustrating the use of the rotary engine. Rising fuel prices and speculation about proposed US emission standards legislation also increased concerns.
