By 1974, 5,000-plus-pound family cars were suddenly as impractical as the ol’ muscle car had been to newlyweds holding a freshly printed mortgage and a newborn baby just a few years earlier. Detuned as they were, the large-displacement—still a prevalent means of motivation within the market segment-remained incredibly thirsty. As a result, Pontiac’s full-size output fell to just under 145,500 cars in 1975, and only 137,216 were sold a year later.
Suffice it to say, Detroit needed a diet, and the automakers knew it well in advance thanks in large part to looming federal mandates. At GM, the first to be first slimmed down were the 1977 model-year full-size cars. Among them was Pontiac’s flagship station wagon—the Grand Safari.
The downsized wagon’s chassis was reduced from 127 inches to a svelte 115.9 inches. Much of the basic architecture, however, carried over from the previous generation: independent coil spring front suspension, rear leaf-sprung suspension, power steering, and power front disc brakes. Also included as a standard were FR78-15 radial tires that provided sure-footed control in all driving conditions.
The redesigned chassis cradled an equally new 5.0-liter (301-cu.in.) V-8 engine. It was more than the division’s new “economy” powerplant; rated for a rather capable 135 horsepower, the block, crankshaft, cylinder heads, and intake manifold—collectively—weighed 136 pounds less than the 350-cu.in. V-8. Factory literature touted the availability of a “new 6.6 litre (400/403 CID) V-8” on the Grand Safari’s option chart—technically a carryover engine revamped for ’77—that was rated for 180 or 200 hp. Californians could have opted for the 170-hp 350. A Turbo Hydra-Matic automatic was the only transmission available.
