The 1972 models saw the first wave of emissions reduction and safety equipment and updates. GTO was a now sub-series of the LeMans series. The Tempest was dropped, after being renamed 'T-37' and 'GT-37' for 1971. The base 1972 mid-sized Pontiac was now called LeMans. James MacDonald left the post of general manager to be replaced by Martin J. Caserio in late 1972. Caserio was the first manager in over a decade to be more focused on marketing and sales than on performance.
