1977 Pontiac LeMans

The year 1977 was the finale for the LeMans and Grand LeMans built off the 1973-vintage Colonnade body. Appearance changes were limited to revised grilles and tailight lenses. Engine offerings were revised with Buick's 231 cubic-inch V6 replacing the Chevy inline six as the base powerplant in sedans and coupes.

The base V8 (standard on Safari wagons and optional on other models) was Pontiac's new 301 cubic-inch engine based on the same V8 engine block as other Pontiac V8s but utilized many lightweight components. Optional V8s were pared down to Pontiac-built 350 and 400 four-barrel powerplants. The three-speed manual was the standard transmission on V6 models, while the Turbo Hydra-matic was optional and the only transmission available with the V8 engines. Those drivetrain offerings were available in 49 states.

In California, Pontiac V8s were not offered for 1977 due to the inability to meet that state's more stringent regulations. In the Golden State, the Buick V6 was standard on most models but the V8 engines offered there were Oldsmobile's 350 and 403 four-barrel engines. Turbo Hydra-matic was the only transmission offered in California.

A sporty/performance model based on the LeMans Sport Coupe called the Pontiac Can Am was a one-year only offering for 1977. The Can Am came standard with the 400 four-barrel V8 in 49 states or the Olds 403 four-barrel in California, along with Turbo Hydra-matic transmission, a Grand Prix instrument panel and console, along with Strato bucket seats, and rear spoiler.

For the final year of the Colonnade LeMans models, they were joined by newly downsized B-body Catalina and Bonneville full-sized cars, which weighed a few pounds less than the "intermediates" and rode on the same 116-inch wheelbase length as the LeMans sedans and Safari wagons and also had similar dimensions as far as length and width were concerned. The downsized big cars of 1977, would be followed up with downsized intermediates for 1978 including the LeMans/Grand LeMans and the personal-luxury Grand Prix coupe.

  1. I had a 1977 Pontiac Grand Lemans Coupe. I could kick myself for not keeping it.
