GM X platform (1962)


The rear-wheel drive X-body underpinned the Chevrolet Nova and similar cars of the 1960s and 1970s. It was also the basis for the Cadillac Seville's K platform and many components were shared with the contemporary F platform. Entry level badge engineered luxury coupes and sedans offered in the 1970s by Buick, Pontiac, and Oldsmobile appeared around the same time as the competing Ford Granada and Plymouth Volare.
Applications:
Model year 1968–1974 GM X-bodies positioned the steering linkage behind the steering gear, whereas 1975–1979 models had the steering linkage forward of the steering gear F platform including the 1973–1977 A platform and 1977–1996 B platform.
In the early 1970s, it was noticed that the first letter of each X-body model name spelled out "NOVA", the cheapest model of the quartet.
