1977 Buick Electra Park Avenue: Buick’s Big Downsizing Gamble Pays Off Handsomely (But Oh, That Interior!)

Take one full-size American near-luxury car, lop a foot off its overall length, subtract over 100 cubic inches of engine displacement, and raise the price by hundreds of dollars. It sounds like a recipe for disaster, but in 1977, it became one of Buick’s biggest success stories. The downsized Buick Electra hit a late ’70s sweet spot, packing ample interior space and crushed velour extravagance into a more rationally sized but still very profitable package.

If you’re reading Curbside Classic, you’re probably at least somewhat familiar with GM’s first big wave of downsizing. In the ’70s, General Motors kicked off a $15 billion program (the equivalent of over $250 billion in 2026 dollars) to shrink most of its cars, beginning with the full-size lines. As Paul has previously explained, the market share of full-size cars had been on the decline for quite a while, but the bigger models were still GM’s bread and butter. In the 1979 book On a Clear Day You Can See General Motors, former GM executive John DeLorean explained it like this:

General Motors’ forte historically has been selling big cars. Its large profits have come from bigger, more expensive cars. It is in the intermediate and full-sized car markets that GM has dominated. This has been a corporate objective. American car customers, historically, have been willing to pay hundreds of dollars more for a few extra pounds and inches in their cars. The returns to the company are obvious. When I was with GM, a $300 to $400 difference between the building costs of a Chevrolet Caprice and a Cadillac DeVille, a bigger car, was small compared to a $3,800 difference in the sticker price. The difference in profit to General Motors on the two cars is over $2,000. Within the Chevrolet itself, the Caprice, a full-sized car, generated about $200 more profit per car on the average than the Chevelle, an intermediate, and about $400 more than the Nova, a compact.

It wasn’t that GM didn’t make money on compacts, intermediates, and pony cars — they did — but they didn’t make as much money. Those smaller models filled certain important niches, and dealers sometimes insisted on them so they’d always have something to sell if the economy shifted abruptly. Nonetheless, selling a given number of full-size cars was almost always worth more than selling the same number of midsize or compact cars. So, GM had a lot of incentive to keep its full-size cars, and to keep them commercially viable for as long as possible.

There’s a common misconception that the 1977–1978 downsizing program was motivated by federal Corporate Average Fuel Economy (CAFE) requirements, which first took effect for the 1978 model year. In fact, GM had begun what they called “Project 77” in June 1973, and it was well under way by the time GM officials went before Congress in the summer of 1975 to argue that their multi-billion-dollar downsizing program would make the CAFE rules unnecessary. (Congress disagreed.) Whether the downsizing would have gone ahead if not for the 1973–1974 oil embargo is anybody’s guess, but the embargo made it a necessity, particularly for the mid-price brands.

You might assume that buyers of big Oldsmobiles and Buicks wouldn’t care that much about gas mileage or gas prices, and in the past, they mostly hadn’t. However, sales of full-size Olds and Buick models had tumbled by about 50 percent in the 1974 model year, and they weren’t any better for 1975. The intermediate Cutlass and Century kept this from being a complete disaster, but even in 1976, sales of the very lucrative full-size models still lagged way behind their 1973 levels. Nobody was crying about Olds selling half a million Cutlasses and Buick selling 300,000 Century/Regal intermediates, but they knew they would have been making more money if those buyers had bought big cars instead.

So, the downsized 1977 full-size cars were both a huge risk and a great opportunity: They might either resuscitate GM’s mid-priced cash cows or wound them beyond recovery.

As I’ve said before, I don’t think the 1977 GM C-body cars were particularly graceful-looking. The slightly smaller B-body models had more flair, with the Chevrolet Caprice/Impala a particular highlight, but to my eyes, the C-body was squarish and a bit stodgy even in two-door form.

Personally, I think the 1977 Olds Ninety-Eight four-door pulled off the new C-body best, but you can judge for yourself.

However, whatever the new models may have lacked in looks, they made up in space efficiency. Buick boasted that some of the downsized cars actually had more room in back and in the trunk than their predecessors, but for the big Electra 225/Limited four-door sedan, it was really more of a draw: Front and rear headroom and legroom were almost identical to the ’76, although the ’77 car’s narrower width did cost it a small but perceptible amount of hip and shoulder room.

Trunk space improved by a mere 0.1 cubic feet, but considering that the Electra had shrunk by 12.2 inches in overall length, 8.1 inches in wheelbase, and around 700 lb of curb weight, maintaining the same passenger and luggage space was still an admirable achievement.

The big theme of Buick marketing for 1977 was reassurance. Sure, the cars were a bit smaller, Buick told buyers, but they “offer a trimness in exterior design while maintaining the spacious comfort of traditional full-size cars within.” Yes, they were a trifle firmer, but “that great Buick ride is there, and there is also a new feeling of tautness.”

The familiar 455 was also gone, replaced by the Buick 350, with 155 hp, and the optional Olds 403, with 185 hp. “Both are trusty sources of power like the old 7.5 litre V-8,” Buick said, “but work with significantly less displacement. Which means there are fewer cc’s to feed.” (They also had fewer pounds to haul, although Buick didn’t stress that point as much as some of its fellow divisions did.) In truth, even the 350 was still not that economical in the real world, but the gas mileage of previous full-size Buicks had gotten so grim that the 1977 car’s 15–16 mpg represented an improvement of better than 50 percent.

Then, of course, there was the interior, which was as lavish as ever.

Some of the magazine reviewers would have preferred if Buick and Oldsmobile had taken this opportunity to tone down the gingerbread, but neither division had any intention of doing that. The crushed velour/shag carpeting/woodgrain look was popular, it was profitable, and it helped to dispel any sense of sacrifice that might accompany the revised exterior dimensions.

This was an important point because these cars were actually more expensive than their predecessors — the base price of an Electra Limited four-door was up a significant $374 from 1976, around 5 percent. The simulated wood trim and brushed aluminum instrument faces were further reassurance that you were still getting what you were paying for.

Nowhere was this more pronounced than in the Electra Park Avenue. First introduced for 1975, the Park Avenue was an interior option for the Electra Limited ($325 in 1977), with extra-plush seating.

The interior of the regular Electra Limited was already pretty extravagant, but the Park Avenue went full bordello, like the outgoing Cadillac Fleetwood Talisman.

Whether you loved or loathed this sort of thing, it emphasized that the new Electra was still as indulgent as ever, even though it now had fewer calories and lower cholesterol.

All this had the desired effect, and then some. Surprisingly, the downsized big cars did no harm at all to Oldsmobile and Buick intermediates, which sold even better for 1977. However, sales of the full-size cars picked up very smartly: Oldsmobile and Buick each sold about 100,000 MORE full-size cars than they had in 1976.

Moreover, a lot of that growth was in the C-body lines — the Electra Limited picked up more than 40,000 additional sales. That made Buick a lot more money: An Electra Limited listed for $1,844 more than the B-body LeSabre Custom, and I would be surprised if the difference in production cost amounted to more than one-third of that. It was also a clear sign that even very affluent buyers had accepted the downsized models.

In the long run, full-size cars were still on an inexorable decline (and by the late ’70s, I’m pretty sure GM knew that). However, in the short term, downsizing gave these big Buicks and Oldsmobiles a shot of adrenaline, and gave GM a few more very profitable years. It had been a huge gamble, but it had a huge payoff: GM posted a $3.3 billion profit in 1977 and a record-setting $3.5 billion in 1978. Numbers like that aren’t nearly as exciting to most enthusiasts as lap times and quarter-mile ETs, but to automakers, they’re the name of the game.
