Nearly 250,000 1973 Pontiac LeMans/Grand Am were built, some 16% over the previous (1970) reshape.  This was below its GM siblings, and probably due to its jelly bean shape at the rear, which apparently wasn’t appropriate to be fitted with the formal roof that boosted sales for the Buick and Oldsmobile intermediates.  Besides, it had the Grand Prix.  Pontiac then inserted a formal-look window in its semi-fastback roof for the Luxury LeMans the next year, which was optional for the Sport Coupe and by 1975 also for the sporty Grand Am.  By 1976 it became standard in the base LeMans.  However, in 1977 the production was down to a mere 80,000 units. 

The 1975 Grand LeMans had a hood ornament and the full line received rectangular headlights by 1976, when the relatively slow selling Grand Am was deleted.  The Grand Prix, on the 4-door wheelbase, and with a real formal roof, of course was the true favorite of Pontiac’s intermediate line, selling a whopping 8 times as much as the other Pontiac intermediate coupes in 1977.  It is ironical that the 4 inches extra length of the wheelbase was granted to the longer hood, rather than the interior room, which was equal to the LeMans coupes.

Under the skin:

At first, nine engines were offered, ranging from the 250 Chevy 6-cylinder-in-line to the Pontiac V8 455, expanded to eleven in 1974, when 4-barrel 350s were added.  This is without 2 Chevrolet 350 engines which were sold in Canada.  Then in 1975 the total number was down to six when the catalytic converter restricted the use of dual exhausts, but the usual four engine sizes remained.  A 260 Oldsmobile engine with available 5-speed came in for 1976, but was replaced the next year by a 350-derived Pontiac 301 (5-liter).   A next Oldsmobile 403 engine replaced the Pontiac 455 as top choice, but for 200 hp you had to opt for the Pontiac Can Am (sic).  In 1977 as well, Pontiac chose to replace their Chevrolet six by the more economical Buick V6.  Including California and Canada, V8 350 engines were available from three manufacturers (Pontiac, Oldsmobile and Chevrolet).

Power brakes and power steering remained optional for the lesser models through 1977.  15-inch wheels with radial tires replaced the 14-inch wheels by 1975, but Canada held the 14” wheels for another year in the basic LeMans models.
