The first four generations of the Monte Carlo (1970–1972, 1973–1977, 1978–1980, and 1981–1988) were of a rear-wheel-drive, V8-powered (a V6 engine from 1978) coupe design, using body-on-frame construction. The later rear-wheel-drive generations did not incorporate the trend of uni-body construction that became more prevalent in the early 1980s as automakers downsized their vehicle lines to satisfy increasing demand for fuel-economy after the 1973 oil crisis and the early 1980s recession.
