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 by Buick, Pontiac, and Oldsmobile appeared around the same time as the competing Ford Granada and Plymouth Volare.

1968–1974 GM X-bodies positioned the steering linkage behind the steering gear ("rear steer" - also shared with the 1967-69 F platform), whereas 1975–1979 models had the steering linkage forward of the steering gear ("front steer" - shared with the second generation (1970-81) F platform including the 1973-77 A platform and 1977-96 B platform (control arms, steering knuckle assembly except steering linkage and front sway bar).
In the early 1970s, it was noticed that the first letter of each X-body model name (Nova, Omega, Ventura, Apollo) spelled out "NOVA", the cheapest model of the quartet.
