The fourth-generation Pontiac LeMans was produced from 1973 to 1977 on General Motors' redesigned intermediate A-body architecture featuring heavy Colonnade styling with fixed B-pillars and frameless door glass. Available body styles encompassed two-door coupes with fixed quarter windows, four-door sedans, and station wagons. Standard power came from inline-six engines, while mid-to-high tiers featured Pontiac's own 5.7-liter, 6.6-liter, and 7.5-liter V8 engines mated to automatic or manual transmissions. The primary evolution from the prior generation was the adoption of bulky 5-mph energy-absorbing front bumpers, increased overall weight, and reinforced crash structures mandated by federal regulations. Suspension geometry was significantly upgraded to improve ride comfort and handling composure. Minor yearly facelifts kept the front fascia and trim modern through the mid-1970s. The primary sales market was North America, where these full-featured midsize cars appealed to buyers seeking comfort, highway stability, and classic styling.
