From 1970, the Rebel and Ambassador were identical from the A-pillar back. The Ambassador continued as AMC's upmarket model with higher trim, more equipment, and air conditioning as standard. From the A-pillar forward, the Ambassador was redesigned and stretched {{convert|7|in|mm|0}} to become the biggest ever, just as the 1973 [[1973 oil crisis|Arab Oil Embargo]] sparked gasoline rationing across the nation. The additional length was due to a new front-end design and more substantial energy-absorbing bumpers required of all automobiles sold in the U.S.<ref>{{cite magazine|first=Jan P. |last=Norbye |title=New bumpers have uniform height, take angle impacts|magazine=Popular Science |pages=90–91|date=October 1973 |url= https://books.google.com/books?id=lpiMSzja6W4C&pg=PA90 |volume=203 |issue=4 |access-date=January 16, 2011}}</ref> Sales of all large cars fell due to economic problems and rising gasoline prices. The Ambassador became a full-sized car in 1974 and was discontinued after the 1974 model year, leaving only the Matador as American Motors' full-size offering. Nash and American Motors made Ambassadors from 1927 through 1974, the longest use of the same model name for any American Motors product and, at the time, the longest continuously used nameplate in the industry.
